Classes

Api

Api is a light-weight descriptor for an API Interface. Interfaces are also described as "protocol buffer services" in some contexts, such as by the "service" keyword in a .proto file, but they are different from API Services, which represent a concrete implementation of an interface as opposed to simply a description of methods and bindings. They are also sometimes simply referred to as "APIs" in other contexts, such as the name of this message itself. See https://cloud.google.com/apis/design/glossary for detailed terminology.

AuthProvider

Configuration for an authentication provider, including support for JSON Web Token (JWT).

AuthRequirement

User-defined authentication requirements, including support for JSON Web Token (JWT).

Authentication

Authentication defines the authentication configuration for API methods provided by an API service. Example: name: calendar.googleapis.com authentication: providers: - id: google_calendar_auth jwks_uri: https://www.googleapis.com/oauth2/v1/certs issuer: https://securetoken.google.com rules: - selector: "*" requirements: provider_id: google_calendar_auth - selector: google.calendar.Delegate oauth: canonical_scopes: https://www.googleapis.com/auth/calendar.read

AuthenticationRule

Authentication rules for the service. By default, if a method has any authentication requirements, every request must include a valid credential matching one of the requirements. It's an error to include more than one kind of credential in a single request. If a method doesn't have any auth requirements, request credentials will be ignored.

Backend

Backend defines the backend configuration for a service.

BackendRule

A backend rule provides configuration for an individual API element.

Billing

Billing related configuration of the service. The following example shows how to configure monitored resources and metrics for billing, consumer_destinations is the only supported destination and the monitored resources need at least one label key cloud.googleapis.com/location to indicate the location of the billing usage, using different monitored resources between monitoring and billing is recommended so they can be evolved independently: monitored_resources: - type: library.googleapis.com/billing_branch labels: - key: cloud.googleapis.com/location description: | Predefined label to support billing location restriction. - key: city description: | Custom label to define the city where the library branch is located in. - key: name description: Custom label to define the name of the library branch. metrics: - name: library.googleapis.com/book/borrowed_count metric_kind: DELTA value_type: INT64 unit: "1" billing: consumer_destinations: - monitored_resource: library.googleapis.com/billing_branch metrics: - library.googleapis.com/book/borrowed_count

BillingDestination

Configuration of a specific billing destination (Currently only support bill against consumer project).

ClientLibrarySettings

Details about how and where to publish client libraries.

CommonLanguageSettings

Required information for every language.

Context

Context defines which contexts an API requests. Example: context: rules: - selector: "*" requested: - google.rpc.context.ProjectContext - google.rpc.context.OriginContext The above specifies that all methods in the API request google.rpc.context.ProjectContext and google.rpc.context.OriginContext. Available context types are defined in package google.rpc.context. This also provides mechanism to allowlist any protobuf message extension that can be sent in grpc metadata using “x-goog-ext--bin” and “x-goog-ext--jspb” format. For example, list any service specific protobuf types that can appear in grpc metadata as follows in your yaml file: Example: context: rules: - selector: "google.example.library.v1.LibraryService.CreateBook" allowed_request_extensions: - google.foo.v1.NewExtension allowed_response_extensions: - google.foo.v1.NewExtension You can also specify extension ID instead of fully qualified extension name here.

ContextRule

A context rule provides information about the context for an individual API element.

Control

Selects and configures the service controller used by the service. Example: control: environment: servicecontrol.googleapis.com

CppSettings

Settings for C++ client libraries.

CustomError

Customize service error responses. For example, list any service specific protobuf types that can appear in error detail lists of error responses. Example: custom_error: types: - google.foo.v1.CustomError - google.foo.v1.AnotherError

CustomErrorRule

A custom error rule.

CustomHttpPattern

A custom pattern is used for defining custom HTTP verb.

Documentation

Documentation provides the information for describing a service. Example: documentation: summary: > The Google Calendar API gives access to most calendar features. pages: - name: Overview content: (== include google/foo/overview.md ==) - name: Tutorial content: (== include google/foo/tutorial.md ==) subpages: - name: Java content: (== include google/foo/tutorial_java.md ==) rules: - selector: google.calendar.Calendar.Get description: > ... - selector: google.calendar.Calendar.Put description: > ... Documentation is provided in markdown syntax. In addition to standard markdown features, definition lists, tables and fenced code blocks are supported. Section headers can be provided and are interpreted relative to the section nesting of the context where a documentation fragment is embedded. Documentation from the IDL is merged with documentation defined via the config at normalization time, where documentation provided by config rules overrides IDL provided. A number of constructs specific to the API platform are supported in documentation text. In order to reference a proto element, the following notation can be used: [fully.qualified.proto.name][] To override the display text used for the link, this can be used: [display text][fully.qualified.proto.name] Text can be excluded from doc using the following notation: (-- internal comment --) A few directives are available in documentation. Note that directives must appear on a single line to be properly identified. The include directive includes a markdown file from an external source: (== include path/to/file ==) The resource_for directive marks a message to be the resource of a collection in REST view. If it is not specified, tools attempt to infer the resource from the operations in a collection: (== resource_for v1.shelves.books ==) The directive suppress_warning does not directly affect documentation and is documented together with service config validation.

DocumentationRule

A documentation rule provides information about individual API elements.

DotnetSettings

Settings for Dotnet client libraries.

Empty

A generic empty message that you can re-use to avoid defining duplicated empty messages in your APIs. A typical example is to use it as the request or the response type of an API method. For instance: service Foo { rpc Bar(google.protobuf.Empty) returns (google.protobuf.Empty); }

Endpoint

Endpoint describes a network address of a service that serves a set of APIs. It is commonly known as a service endpoint. A service may expose any number of service endpoints, and all service endpoints share the same service definition, such as quota limits and monitoring metrics. Example: type: google.api.Service name: library-example.googleapis.com endpoints: # Declares network address https://library-example.googleapis.com # for service library-example.googleapis.com. The https scheme # is implicit for all service endpoints. Other schemes may be # supported in the future. - name: library-example.googleapis.com allow_cors: false - name: content-staging-library-example.googleapis.com # Allows HTTP OPTIONS calls to be passed to the API frontend, for it # to decide whether the subsequent cross-origin request is allowed # to proceed. allow_cors: true

Enum

Enum type definition.

EnumValue

Enum value definition.

ExperimentalFeatures

Experimental features to be included during client library generation. These fields will be deprecated once the feature graduates and is enabled by default.

Field

A single field of a message type.

FieldPolicy

Google API Policy Annotation This message defines a simple API policy annotation that can be used to annotate API request and response message fields with applicable policies. One field may have multiple applicable policies that must all be satisfied before a request can be processed. This policy annotation is used to generate the overall policy that will be used for automatic runtime policy enforcement and documentation generation.

GoSettings

Settings for Go client libraries.

Http

Defines the HTTP configuration for an API service. It contains a list of HttpRule, each specifying the mapping of an RPC method to one or more HTTP REST API methods.

HttpRule

gRPC Transcoding gRPC Transcoding is a feature for mapping between a gRPC method and one or more HTTP REST endpoints. It allows developers to build a single API service that supports both gRPC APIs and REST APIs. Many systems, including Google APIs, Cloud Endpoints, gRPC Gateway, and Envoy proxy support this feature and use it for large scale production services. HttpRule defines the schema of the gRPC/REST mapping. The mapping specifies how different portions of the gRPC request message are mapped to the URL path, URL query parameters, and HTTP request body. It also controls how the gRPC response message is mapped to the HTTP response body. HttpRule is typically specified as an google.api.http annotation on the gRPC method. Each mapping specifies a URL path template and an HTTP method. The path template may refer to one or more fields in the gRPC request message, as long as each field is a non-repeated field with a primitive (non-message) type. The path template controls how fields of the request message are mapped to the URL path. Example: service Messaging { rpc GetMessage(GetMessageRequest) returns (Message) { option (google.api.http) = { get: "/v1/{name=messages/}" }; } } message GetMessageRequest { string name = 1; // Mapped to URL path. } message Message { string text = 1; // The resource content. } This enables an HTTP REST to gRPC mapping as below: - HTTP: GET /v1/messages/123456 - gRPC: GetMessage(name: "messages/123456") Any fields in the request message which are not bound by the path template automatically become HTTP query parameters if there is no HTTP request body. For example: service Messaging { rpc GetMessage(GetMessageRequest) returns (Message) { option (google.api.http) = { get:"/v1/messages/{message_id}" }; } } message GetMessageRequest { message SubMessage { string subfield = 1; } string message_id = 1; // Mapped to URL path. int64 revision = 2; // Mapped to URL query parameter revision. SubMessage sub = 3; // Mapped to URL query parameter sub.subfield. } This enables a HTTP JSON to RPC mapping as below: - HTTP: GET /v1/messages/123456?revision=2&sub.subfield=foo - gRPC: GetMessage(message_id: "123456" revision: 2 sub: SubMessage(subfield: "foo")) Note that fields which are mapped to URL query parameters must have a primitive type or a repeated primitive type or a non-repeated message type. In the case of a repeated type, the parameter can be repeated in the URL as ...?param=A&param=B. In the case of a message type, each field of the message is mapped to a separate parameter, such as ...?foo.a=A&foo.b=B&foo.c=C. For HTTP methods that allow a request body, the body field specifies the mapping. Consider a REST update method on the message resource collection: service Messaging { rpc UpdateMessage(UpdateMessageRequest) returns (Message) { option (google.api.http) = { patch: "/v1/messages/{message_id}" body: "message" }; } } message UpdateMessageRequest { string message_id = 1; // mapped to the URL Message message = 2; // mapped to the body } The following HTTP JSON to RPC mapping is enabled, where the representation of the JSON in the request body is determined by protos JSON encoding: - HTTP: PATCH /v1/messages/123456 { "text": "Hi!" } - gRPC: UpdateMessage(message_id: "123456" message { text: "Hi!" }) The special name * can be used in the body mapping to define that every field not bound by the path template should be mapped to the request body. This enables the following alternative definition of the update method: service Messaging { rpc UpdateMessage(Message) returns (Message) { option (google.api.http) = { patch: "/v1/messages/{message_id}" body: "" }; } } message Message { string message_id = 1; string text = 2; } The following HTTP JSON to RPC mapping is enabled: - HTTP: PATCH /v1/messages/123456 { "text": "Hi!" } - gRPC: UpdateMessage(message_id: "123456" text: "Hi!") Note that when using * in the body mapping, it is not possible to have HTTP parameters, as all fields not bound by the path end in the body. This makes this option more rarely used in practice when defining REST APIs. The common usage of * is in custom methods which don't use the URL at all for transferring data. It is possible to define multiple HTTP methods for one RPC by using the additional_bindings option. Example: service Messaging { rpc GetMessage(GetMessageRequest) returns (Message) { option (google.api.http) = { get: "/v1/messages/{message_id}" additional_bindings { get: "/v1/users/{user_id}/messages/{message_id}" } }; } } message GetMessageRequest { string message_id = 1; string user_id = 2; } This enables the following two alternative HTTP JSON to RPC mappings: - HTTP: GET /v1/messages/123456 - gRPC: GetMessage(message_id: "123456") - HTTP: GET /v1/users/me/messages/123456 - gRPC: GetMessage(user_id: "me" message_id: "123456") Rules for HTTP mapping 1. Leaf request fields (recursive expansion nested messages in the request message) are classified into three categories: - Fields referred by the path template. They are passed via the URL path. - Fields referred by the HttpRule.body. They are passed via the HTTP request body. - All other fields are passed via the URL query parameters, and the parameter name is the field path in the request message. A repeated field can be represented as multiple query parameters under the same name. 2. If HttpRule.body is "", there is no URL query parameter, all fields are passed via URL path and HTTP request body. 3. If HttpRule.body is omitted, there is no HTTP request body, all fields are passed via URL path and URL query parameters. Path template syntax Template = "/" Segments [ Verb ] ; Segments = Segment { "/" Segment } ; Segment = "" | "**" | LITERAL | Variable ; Variable = "{" FieldPath [ "=" Segments ] "}" ; FieldPath = IDENT { "." IDENT } ; Verb = ":" LITERAL ; The syntax * matches a single URL path segment. The syntax ** matches zero or more URL path segments, which must be the last part of the URL path except the Verb. The syntax Variable matches part of the URL path as specified by its template. A variable template must not contain other variables. If a variable matches a single path segment, its template may be omitted, e.g. {var} is equivalent to {var=*}. The syntax LITERAL matches literal text in the URL path. If the LITERAL contains any reserved character, such characters should be percent-encoded before the matching. If a variable contains exactly one path segment, such as "{var}" or "{var=*}", when such a variable is expanded into a URL path on the client side, all characters except [-_.~0-9a-zA-Z] are percent-encoded. The server side does the reverse decoding. Such variables show up in the Discovery Document as {var}. If a variable contains multiple path segments, such as "{var=foo/*}" or "{var=**}", when such a variable is expanded into a URL path on the client side, all characters except [-_.~/0-9a-zA-Z] are percent-encoded. The server side does the reverse decoding, except "%2F" and "%2f" are left unchanged. Such variables show up in the Discovery Document as {+var}. Using gRPC API Service Configuration gRPC API Service Configuration (service config) is a configuration language for configuring a gRPC service to become a user-facing product. The service config is simply the YAML representation of the google.api.Service proto message. As an alternative to annotating your proto file, you can configure gRPC transcoding in your service config YAML files. You do this by specifying a HttpRule that maps the gRPC method to a REST endpoint, achieving the same effect as the proto annotation. This can be particularly useful if you have a proto that is reused in multiple services. Note that any transcoding specified in the service config will override any matching transcoding configuration in the proto. The following example selects a gRPC method and applies an HttpRule to it: http: rules: - selector: example.v1.Messaging.GetMessage get: /v1/messages/{message_id}/{sub.subfield} Special notes When gRPC Transcoding is used to map a gRPC to JSON REST endpoints, the proto to JSON conversion must follow the proto3 specification. While the single segment variable follows the semantics of RFC 6570 Section 3.2.2 Simple String Expansion, the multi segment variable does not follow RFC 6570 Section 3.2.3 Reserved Expansion. The reason is that the Reserved Expansion does not expand special characters like ? and #, which would lead to invalid URLs. As the result, gRPC Transcoding uses a custom encoding for multi segment variables. The path variables must not refer to any repeated or mapped field, because client libraries are not capable of handling such variable expansion. The path variables must not capture the leading "/" character. The reason is that the most common use case "{var}" does not capture the leading "/" character. For consistency, all path variables must share the same behavior. Repeated message fields must not be mapped to URL query parameters, because no client library can support such complicated mapping. If an API needs to use a JSON array for request or response body, it can map the request or response body to a repeated field. However, some gRPC Transcoding implementations may not support this feature.

JavaSettings

Settings for Java client libraries.

JwtLocation

Specifies a location to extract JWT from an API request.

LabelDescriptor

A description of a label.

LogDescriptor

A description of a log type. Example in YAML format: - name: library.googleapis.com/activity_history description: The history of borrowing and returning library items. display_name: Activity labels: - key: /customer_id description: Identifier of a library customer

Logging

Logging configuration of the service. The following example shows how to configure logs to be sent to the producer and consumer projects. In the example, the activity_history log is sent to both the producer and consumer projects, whereas the purchase_history log is only sent to the producer project. monitored_resources:

type: library.googleapis.com/branch labels: - key: /city description: The city where the library branch is located in. - key: /name description: The name of the branch. logs: - name: activity_history labels: - key: /customer_id - name: purchase_history logging: producer_destinations: - monitored_resource: library.googleapis.com/branch logs: - activity_history - purchase_history consumer_destinations: - monitored_resource: library.googleapis.com/branch logs: - activity_history

LoggingDestination

Configuration of a specific logging destination (the producer project or the consumer project).

LongRunning

Describes settings to use when generating API methods that use the long-running operation pattern. All default values below are from those used in the client library generators (e.g. Java).

Method

Method represents a method of an API interface.

MethodPolicy

Defines policies applying to an RPC method.

MethodSettings

Describes the generator configuration for a method.

MetricDescriptor

Defines a metric type and its schema. Once a metric descriptor is created, deleting or altering it stops data collection and makes the metric type's existing data unusable.

MetricDescriptorMetadata

Additional annotations that can be used to guide the usage of a metric.

MetricRule

Bind API methods to metrics. Binding a method to a metric causes that metric's configured quota behaviors to apply to the method call.

Mixin

Declares an API Interface to be included in this interface. The including interface must redeclare all the methods from the included interface, but documentation and options are inherited as follows: - If after comment and whitespace stripping, the documentation string of the redeclared method is empty, it will be inherited from the original method. - Each annotation belonging to the service config (http, visibility) which is not set in the redeclared method will be inherited. - If an http annotation is inherited, the path pattern will be modified as follows. Any version prefix will be replaced by the version of the including interface plus the root path if specified. Example of a simple mixin: package google.acl.v1; service AccessControl { // Get the underlying ACL object. rpc GetAcl(GetAclRequest) returns (Acl) { option (google.api.http).get = "/v1/{resource=}:getAcl"; } } package google.storage.v2; service Storage { // rpc GetAcl(GetAclRequest) returns (Acl); // Get a data record. rpc GetData(GetDataRequest) returns (Data) { option (google.api.http).get = "/v2/{resource=}"; } } Example of a mixin configuration: apis: - name: google.storage.v2.Storage mixins: - name: google.acl.v1.AccessControl The mixin construct implies that all methods in AccessControl are also declared with same name and request/response types in Storage. A documentation generator or annotation processor will see the effective Storage.GetAcl method after inheriting documentation and annotations as follows: service Storage { // Get the underlying ACL object. rpc GetAcl(GetAclRequest) returns (Acl) { option (google.api.http).get = "/v2/{resource=}:getAcl"; } ... } Note how the version in the path pattern changed from v1 to v2. If the root field in the mixin is specified, it should be a relative path under which inherited HTTP paths are placed. Example: apis: - name: google.storage.v2.Storage mixins: - name: google.acl.v1.AccessControl root: acls This implies the following inherited HTTP annotation: service Storage { // Get the underlying ACL object. rpc GetAcl(GetAclRequest) returns (Acl) { option (google.api.http).get = "/v2/acls/{resource=}:getAcl"; } ... }

MonitoredResourceDescriptor

An object that describes the schema of a MonitoredResource object using a type name and a set of labels. For example, the monitored resource descriptor for Google Compute Engine VM instances has a type of "gce_instance" and specifies the use of the labels "instance_id" and "zone" to identify particular VM instances. Different APIs can support different monitored resource types. APIs generally provide a list method that returns the monitored resource descriptors used by the API.

Monitoring

Monitoring configuration of the service. The example below shows how to configure monitored resources and metrics for monitoring. In the example, a monitored resource and two metrics are defined. The library.googleapis.com/book/returned_count metric is sent to both producer and consumer projects, whereas the library.googleapis.com/book/num_overdue metric is only sent to the consumer project. monitored_resources: - type: library.googleapis.com/Branch display_name: "Library Branch" description: "A branch of a library." launch_stage: GA labels: - key: resource_container description: "The Cloud container (ie. project id) for the Branch." - key: location description: "The location of the library branch." - key: branch_id description: "The id of the branch." metrics: - name: library.googleapis.com/book/returned_count display_name: "Books Returned" description: "The count of books that have been returned." launch_stage: GA metric_kind: DELTA value_type: INT64 unit: "1" labels: - key: customer_id description: "The id of the customer." - name: library.googleapis.com/book/num_overdue display_name: "Books Overdue" description: "The current number of overdue books." launch_stage: GA metric_kind: GAUGE value_type: INT64 unit: "1" labels: - key: customer_id description: "The id of the customer." monitoring: producer_destinations: - monitored_resource: library.googleapis.com/Branch metrics: - library.googleapis.com/book/returned_count consumer_destinations: - monitored_resource: library.googleapis.com/Branch metrics: - library.googleapis.com/book/returned_count - library.googleapis.com/book/num_overdue

MonitoringDestination

Configuration of a specific monitoring destination (the producer project or the consumer project).

NodeSettings

Settings for Node client libraries.

OAuthRequirements

OAuth scopes are a way to define data and permissions on data. For example, there are scopes defined for "Read-only access to Google Calendar" and "Access to Cloud Platform". Users can consent to a scope for an application, giving it permission to access that data on their behalf. OAuth scope specifications should be fairly coarse grained; a user will need to see and understand the text description of what your scope means. In most cases: use one or at most two OAuth scopes for an entire family of products. If your product has multiple APIs, you should probably be sharing the OAuth scope across all of those APIs. When you need finer grained OAuth consent screens: talk with your product management about how developers will use them in practice. Please note that even though each of the canonical scopes is enough for a request to be accepted and passed to the backend, a request can still fail due to the backend requiring additional scopes or permissions.

Operation

This resource represents a long-running operation that is the result of a network API call.

Option

A protocol buffer option, which can be attached to a message, field, enumeration, etc.

Page

Represents a documentation page. A page can contain subpages to represent nested documentation set structure.

PhpSettings

Publishing

This message configures the settings for publishing Google Cloud Client libraries generated from the service config.

PythonSettings

Settings for Python client libraries.

Quota

Quota configuration helps to achieve fairness and budgeting in service usage. The metric based quota configuration works this way: - The service configuration defines a set of metrics. - For API calls, the quota.metric_rules maps methods to metrics with corresponding costs. - The quota.limits defines limits on the metrics, which will be used for quota checks at runtime. An example quota configuration in yaml format: quota: limits: - name: apiWriteQpsPerProject metric: library.googleapis.com/write_calls unit: "1/min/{project}" # rate limit for consumer projects values: STANDARD: 10000 (The metric rules bind all methods to the read_calls metric, except for the UpdateBook and DeleteBook methods. These two methods are mapped to the write_calls metric, with the UpdateBook method consuming at twice rate as the DeleteBook method.) metric_rules: - selector: "*" metric_costs: library.googleapis.com/read_calls: 1 - selector: google.example.library.v1.LibraryService.UpdateBook metric_costs: library.googleapis.com/write_calls: 2 - selector: google.example.library.v1.LibraryService.DeleteBook metric_costs: library.googleapis.com/write_calls: 1 Corresponding Metric definition: metrics: - name: library.googleapis.com/read_calls display_name: Read requests metric_kind: DELTA value_type: INT64 - name: library.googleapis.com/write_calls display_name: Write requests metric_kind: DELTA value_type: INT64

QuotaLimit

QuotaLimit defines a specific limit that applies over a specified duration for a limit type. There can be at most one limit for a duration and limit type combination defined within a QuotaGroup.

RubySettings

SelectiveGapicGeneration

This message is used to configure the generation of a subset of the RPCs in a service for client libraries.

Service

Service is the root object of Google API service configuration (service config). It describes the basic information about a logical service, such as the service name and the user-facing title, and delegates other aspects to sub-sections. Each sub-section is either a proto message or a repeated proto message that configures a specific aspect, such as auth. For more information, see each proto message definition. Example: type: google.api.Service name: calendar.googleapis.com title: Google Calendar API apis: - name: google.calendar.v3.Calendar visibility: rules: - selector: "google.calendar.v3." restriction: PREVIEW backend: rules: - selector: "google.calendar.v3." address: calendar.example.com authentication: providers: - id: google_calendar_auth jwks_uri: https://www.googleapis.com/oauth2/v1/certs issuer: https://securetoken.google.com rules: - selector: "*" requirements: provider_id: google_calendar_auth

SourceContext

SourceContext represents information about the source of a protobuf element, like the file in which it is defined.

SourceInfo

Source information used to create a Service Config

Status

The Status type defines a logical error model that is suitable for different programming environments, including REST APIs and RPC APIs. It is used by gRPC. Each Status message contains three pieces of data: error code, error message, and error details. You can find out more about this error model and how to work with it in the API Design Guide.

SystemParameter

Define a parameter's name and location. The parameter may be passed as either an HTTP header or a URL query parameter, and if both are passed the behavior is implementation-dependent.

SystemParameterRule

Define a system parameter rule mapping system parameter definitions to methods.

SystemParameters

System parameter configuration A system parameter is a special kind of parameter defined by the API system,

not by an individual API. It is typically mapped to an HTTP header and/or a URL query parameter. This configuration specifies which methods change the names of the system parameters.

Type

A protocol buffer message type.

Usage

Configuration controlling usage of a service.

UsageRule

Usage configuration rules for the service. NOTE: Under development. Use this rule to configure unregistered calls for the service. Unregistered calls are calls that do not contain consumer project identity. (Example: calls that do not contain an API key). By default, API methods do not allow unregistered calls, and each method call must be identified by a consumer project identity. Use this rule to allow/disallow unregistered calls. Example of an API that wants to allow unregistered calls for entire service. usage: rules: - selector: "*" allow_unregistered_calls: true Example of a method that wants to allow unregistered calls. usage: rules: - selector: "google.example.library.v1.LibraryService.CreateBook" allow_unregistered_calls: true
