Responses

🟢200Success

application/json

Body

AuthorizerCredentialsArn

string

optional

Specifies the required credentials as an IAM role for API Gateway to invoke the authorizer. To specify an IAM role for API Gateway to assume, use the role's Amazon Resource Name (ARN). To use resource-based permissions on the Lambda function, don't specify this parameter. Supported only for REQUEST authorizers.

AuthorizerId

string

optional

The authorizer identifier.

AuthorizerPayloadFormatVersion

string

optional

Specifies the format of the payload sent to an HTTP API Lambda authorizer. Required for HTTP API Lambda authorizers. Supported values are 1.0 and 2.0. To learn more, see Working with AWS Lambda authorizers for HTTP APIs.

AuthorizerResultTtlInSeconds

integer

optional

The time to live (TTL) for cached authorizer results, in seconds. If it equals 0, authorization caching is disabled. If it is greater than 0, API Gateway caches authorizer responses. The maximum value is 3600, or 1 hour. Supported only for HTTP API Lambda authorizers.

>= 0<= 3600

AuthorizerType

enum<string>

optional

The authorizer type. Specify REQUEST for a Lambda function using incoming request parameters. Specify JWT to use JSON Web Tokens (supported only for HTTP APIs).

Allowed values:

REQUESTJWT

AuthorizerUri

string

optional

The authorizer's Uniform Resource Identifier (URI). For REQUEST authorizers, this must be a well-formed Lambda function URI, for example, arn:aws:apigateway:us-west-2:lambda:path/2015-03-31/functions/arn:aws:lambda:us-west-2::function:/invocations. In general, the URI has this form: arn:aws:apigateway::lambda:path/
, where {region} is the same as the region hosting the Lambda function, path indicates that the remaining substring in the URI should be treated as the path to the resource, including the initial /. For Lambda functions, this is usually of the form /2015-03-31/functions/[FunctionARN]/invocations. Supported only for REQUEST authorizers.

EnableSimpleResponses

boolean

optional

Specifies whether a Lambda authorizer returns a response in a simple format. If enabled, the Lambda authorizer can return a boolean value instead of an IAM policy. Supported only for HTTP APIs. To learn more, see Working with AWS Lambda authorizers for HTTP APIs

IdentitySource

object

optional

The identity source for which authorization is requested.

For a REQUEST authorizer, this is optional. The value is a set of one or more mapping expressions of the specified request parameters. The identity source can be headers, query string parameters, stage variables, and context parameters. For example, if an Auth header and a Name query string parameter are defined as identity sources, this value is route.request.header.Auth, route.request.querystring.Name for WebSocket APIs. For HTTP APIs, use selection expressions prefixed with

, f ore x am pl e,

request.header.Auth,
