Creating a Request
Creates a value of GetAuthorizer
with the minimum fields required to make a request.
Use one of the following lenses to modify other fields as desired:
gaaRestAPIId
- [Required] The string identifier of the associatedRestApi
.gaaAuthorizerId
- [Required] The identifier of theAuthorizer
resource.
data GetAuthorizer Source #
Request to describe an existing Authorizer
resource.
See: getAuthorizer
smart constructor.
Request Lenses
gaaRestAPIId :: Lens' GetAuthorizer Text Source #
- Required
- The string identifier of the associated
RestApi
.
gaaAuthorizerId :: Lens' GetAuthorizer Text Source #
- Required
- The identifier of the
Authorizer
resource.
Destructuring the Response
authorizer :: Authorizer Source #
Creates a value of Authorizer
with the minimum fields required to make a request.
Use one of the following lenses to modify other fields as desired:
aAuthorizerURI
- Specifies the authorizer's Uniform Resource Identifier (URI). ForTOKEN
orREQUEST
authorizers, this must be a well-formed Lambda function URI, for example,arn:aws:apigateway:us-west-2:lambda:path2015-03-31functionsarn:aws:lambda:us-west-2:{account_id}:function:{lambda_function_name}invocations
. In general, the URI has this formarn: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 form2015-03-31functions[FunctionARN]invocations
.aIdentityValidationExpression
- A validation expression for the incoming identity token. ForTOKEN
authorizers, this value is a regular expression. API Gateway will match theaud
field of the incoming token from the client against the specified regular expression. It will invoke the authorizer's Lambda function when there is a match. Otherwise, it will return a 401 Unauthorized response without calling the Lambda function. The validation expression does not apply to theREQUEST
authorizer.aProviderARNs
- A list of the Amazon Cognito user pool ARNs for theCOGNITO_USER_POOLS
authorizer. Each element is of this format:arn:aws:cognito-idp:{region}:{account_id}:userpool/{user_pool_id}
. For aTOKEN
orREQUEST
authorizer, this is not defined.aName
- [Required] The name of the authorizer.aId
- The identifier for the authorizer resource.aAuthorizerResultTtlInSeconds
- 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.aAuthType
- Optional customer-defined field, used in Swagger imports and exports without functional impact.aType
- The authorizer type. Valid values areTOKEN
for a Lambda function using a single authorization token submitted in a custom header,REQUEST
for a Lambda function using incoming request parameters, andCOGNITO_USER_POOLS
for using an Amazon Cognito user pool.aIdentitySource
- The identity source for which authorization is requested. * For aTOKEN
orCOGNITO_USER_POOLS
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 isAuth
, the header mapping expression ismethod.request.header.Auth
. * For theREQUEST
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 anAuth
header, aName
query string parameter are defined as identity sources, this value ismethod.request.header.Auth, method.request.querystring.Name
. These parameters will be used to derive the authorization caching key and to perform runtime validation of theREQUEST
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.aAuthorizerCredentials
- 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, specify null.
data Authorizer Source #
Represents an authorization layer for methods. If enabled on a method, API Gateway will activate the authorizer when a client calls the method.
See: authorizer
smart constructor.
Response Lenses
aAuthorizerURI :: Lens' Authorizer (Maybe Text) Source #
Specifies the authorizer's Uniform Resource Identifier (URI). For TOKEN

The authorizer type. Valid values are TOKEN
