AWS::ApiGateway::RestApi

The AWS::ApiGateway::RestApi resource creates a REST API. For more information, see restapi:create in the Amazon API Gateway REST API Reference.

Note

On January 1, 2016, the Swagger Specification was donated to the OpenAPI initiative, becoming the foundation of the OpenAPI Specification.

Properties

ApiKeySourceType

The source of the API key for metering requests according to a usage plan. Valid values are: HEADER to read the API key from the X-API-Key header of a request. AUTHORIZER to read the API key from the UsageIdentifierKey from a custom authorizer.

Required: No

Type: String

Update requires: No interruption

BinaryMediaTypes

The list of binary media types supported by the RestApi. By default, the RestApi supports only UTF-8-encoded text payloads.

Required: No

Type: Array of String

Update requires: No interruption

Body

An OpenAPI specification that defines a set of RESTful APIs in JSON format. For YAML templates, you can also provide the specification in YAML format.

Required: No

Type: Json

Update requires: No interruption

BodyS3Location

The Amazon Simple Storage Service (Amazon S3) location that points to an OpenAPI file, which defines a set of RESTful APIs in JSON or YAML format.

Required: No

Type: S3Location

Update requires: No interruption

CloneFrom

The ID of the RestApi that you want to clone from.

Required: No

Type: String

Update requires: No interruption

Description

The description of the RestApi.

Required: No

Type: String

Update requires: No interruption

DisableExecuteApiEndpoint

Specifies whether clients can invoke your API by using the default execute-api endpoint. By default, clients can invoke your API with the default https://{api_id}.execute-api.{region}.amazonaws.com endpoint. To require that clients use a custom domain name to invoke your API, disable the default endpoint

Required: No

Type: Boolean

Update requires: No interruption

EndpointConfiguration

A list of the endpoint types of the API. Use this property when creating an API. When importing an existing API, specify the endpoint configuration types using the Parameters property.

Required: No

Type: EndpointConfiguration

Update requires: No interruption

FailOnWarnings

A query parameter to indicate whether to rollback the API update (true) or not (false) when a warning is encountered. The default value is false.

Required: No

Type: Boolean

Update requires: No interruption

MinimumCompressionSize

A nullable integer that is used to enable compression (with non-negative between 0 and 10485760 (10M) bytes, inclusive) or disable compression (with a null value) on an API. When compression is enabled, compression or decompression is not applied on the payload if the payload size is smaller than this value. Setting it to zero allows compression for any payload size.

Required: No

Type: Integer

Update requires: No interruption

Mode

This property applies only when you use OpenAPI to define your REST API. The Mode determines how API Gateway handles resource updates.

Valid values are overwrite or merge.

For overwrite, the new API definition replaces the existing one. The existing API identifier remains unchanged.

For merge, the new API definition is merged with the existing API.

If you don't specify this property, a default value is chosen. For REST APIs created before March 29, 2021, the default is overwrite. For REST APIs created after March 29, 2021, the new API definition takes precedence, but any container types such as endpoint configurations and binary media types are merged with the existing API.

Use the default mode to define top-level RestApi properties in addition to using OpenAPI. Generally, it's preferred to use API Gateway's OpenAPI extensions to model these properties.

Required: No

Type: String

Update requires: No interruption

Name

The name of the RestApi. A name is required if the REST API is not based on an OpenAPI specification.

Required: Conditional

Type: String

Update requires: No interruption

Parameters

Custom header parameters as part of the request. For example, to exclude DocumentationParts from an imported API, set ignore=documentation as a parameters value, as in the AWS CLI command of aws apigateway import-rest-api --parameters ignore=documentation --body 'file:///path/to/imported-api-body.json'.

Required: No

Type: Object of String

Pattern: [a-zA-Z0-9]+

Update requires: No interruption

Policy

A policy document that contains the permissions for the RestApi resource. To set the ARN for the policy, use the !Join intrinsic function with "" as delimiter and values of "execute-api:/" and "*".

Required: No

Type: Json

Update requires: No interruption

Tags

The key-value map of strings. The valid character set is [a-zA-Z+-=._:/]. The tag key can be up to 128 characters and must not start with aws:. The tag value can be up to 256 characters.

Required: No

Type: Array of Tag

Update requires: No interruption

Return values

Ref

When you pass the logical ID of this resource to the intrinsic Ref function, Ref returns the RestApi ID, such as a1bcdef2gh.

For more information about using the Ref function, see Ref.

Fn::GetAtt

The Fn::GetAtt intrinsic function returns a value for a specified attribute of this type. The following are the available attributes and sample return values.

For more information about using the Fn::GetAtt intrinsic function, see Fn::GetAtt.

RestApiId

The string identifier of the associated RestApi.

RootResourceId

The root resource ID for a RestApi resource, such as a0bc123d4e.
