Public Method Authorizer()

Properties

NameTypeDescription
Public Property AuthorizerCredentials System.String

Gets and sets the property AuthorizerCredentials.

Specifies the required credentials as an IAM role for Amazon API Gateway to invoke the authorizer. To specify an IAM role for Amazon API Gateway to assume, use the role's Amazon Resource Name (ARN). To use resource-based permissions on the Lambda function, specify null.

Public Property AuthorizerResultTtlInSeconds System.Int32

Gets and sets the property AuthorizerResultTtlInSeconds.

The TTL in seconds of cached authorizer results. If it equals 0, authorization caching is disabled. If it is greater than 0, API Gateway will cache authorizer responses. If this field is not set, the default value is 300. The maximum value is 3600, or 1 hour.

Public Property AuthorizerUri System.String

Gets and sets the property AuthorizerUri.

Specifies the authorizer's Uniform Resource Identifier (URI). For TOKEN or 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:{account_id}:function:{lambda_function_name}/invocations. In general, the URI has this form arn:aws:apigateway:{region}:lambda:path/{service_api}, 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.

Public Property AuthType System.String

Gets and sets the property AuthType.

Optional customer-defined field, used in Swagger imports and exports without functional impact.

Public Property Id System.String

Gets and sets the property Id.

The identifier for the authorizer resource.

Public Property IdentitySource System.String

Gets and sets the property IdentitySource.

The identity source for which authorization is requested.

  • For a TOKEN authorizer, this is required and specifies the request header mapping expression for the custom header holding the authorization token submitted by the client. For example, if the token header name is Auth, the header mapping expression is method.request.header.Auth.
  • For the REQUEST authorizer, this is required when authorization caching is enabled. The value is a comma-separated string of one or more mapping expressions of the specified request parameters. For example, if an Auth header, a Name query string parameter are defined as identity sources, this value is method.request.header.Auth, method.request.querystring.Name. These parameters will be used to derive the authorization caching key and to perform runtime validation of the REQUEST authorizer by verifying all of the identity-related request parameters are present, not null and non-empty. Only when this is true does the authorizer invoke the authorizer Lambda function, otherwise, it returns a 401 Unauthorized response without calling the Lambda function. The valid value is a string of comma-separated mapping expressions of the specified request parameters. When the authorization caching is not enabled, this property is optional.
  • For a COGNITO_USER_POOLS authorizer, this property is not used.

Public Property IdentityValidationExpression System.String

Gets and sets the property IdentityValidationExpression.

A validation expression for the incoming identity token. For TOKEN authorizers, this value is a regular expression. Amazon API Gateway will match the incoming token from the client against the specified regular expression. It will invoke the authorizer's Lambda function there is a match. Otherwise, it will return a 401 Unauthorized response without calling the Lambda function. The validation expression does not apply to the REQUEST authorizer.

Public Property Name System.String

Gets and sets the property Name.

[Required] The name of the authorizer.

Public Property ProviderARNs System.Collections.Generic.List<System.String>

Gets and sets the property ProviderARNs.

A list of the Amazon Cognito user pool ARNs for the COGNITO_USER_POOLS authorizer. Each element is of this format: arn:aws:cognito-idp:{region}:{account_id}:userpool/{user_pool_id}. For a TOKEN or REQUEST authorizer, this is not defined.

Public Property Type Amazon.APIGateway.AuthorizerType

Gets and sets the property Type.

[Required] The authorizer type. Valid values are TOKEN for a Lambda function using a single authorization token submitted in a custom header, REQUEST for a Lambda function using incoming request parameters, and COGNITO_USER_POOLS for using an Amazon Cognito user pool.
