Method Detail

id

public final String id()

The identifier for the authorizer resource.

Returns:

The identifier for the authorizer resource.

name

public final String name()

The name of the authorizer.

Returns:

The name of the authorizer.

type

public final AuthorizerType type()

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.

If the service returns an enum value that is not available in the current SDK version, type will return AuthorizerType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from typeAsString().

Returns:

hasProviderARNs

public final boolean hasProviderARNs()

For responses, this returns true if the service returned a value for the ProviderARNs property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

providerARNs

public final List<String> 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.

Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasProviderARNs() method.

Returns:

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.

authType

public final String authType()

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

Returns:

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

authorizerUri

public final String 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.

Returns:

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.

authorizerCredentials

public final String authorizerCredentials()

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.

Returns:

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.

identitySource

public final String identitySource()

The identity source for which authorization is requested. For a TOKEN or COGNITO_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 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.

Returns:

The identity source for which authorization is requested. For a TOKEN or COGNITO_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 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.

identityValidationExpression

public final String identityValidationExpression()

A validation expression for the incoming identity token. For TOKEN authorizers, this value is a regular expression. For COGNITO_USER_POOLS authorizers, API Gateway will match the aud 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 the REQUEST authorizer.

Returns:

A validation expression for the incoming identity token. For TOKEN authorizers, this value is a regular expression. For COGNITO_USER_POOLS authorizers, API Gateway will match the aud 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 the REQUEST authorizer.

authorizerResultTtlInSeconds

public final Integer 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.

Returns:

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.
