Properties

Name Type Description

Name	Type	Description
AuthorizerResultTtlInSeconds	System.Int32	Gets and sets the property AuthorizerResultTtlInSeconds. The number of seconds a response should be cached for. The default is 0 seconds, which disables caching. If you don't specify a value for `authorizerResultTtlInSeconds`, the default value is used. The maximum value is one hour (3600 seconds). The Lambda function can override this by returning a `ttlOverride` key in its response.
AuthorizerUri	System.String	Gets and sets the property AuthorizerUri. The Amazon Resource Name (ARN) of the Lambda function to be called for authorization. This can be a standard Lambda ARN, a version ARN (`.../v3`), or an alias ARN. Note: This Lambda function must have the following resource-based policy assigned to it. When configuring Lambda authorizers in the console, this is done for you. To use the Command Line Interface (CLI), run the following: `aws lambda add-permission --function-name "arn:aws:lambda:us-east-2:111122223333:function:my-function" --statement-id "appsync" --principal appsync.amazonaws.com --action lambda:InvokeFunction`
IdentityValidationExpression	System.String	Gets and sets the property IdentityValidationExpression. A regular expression for validation of tokens before the Lambda function is called.
