Properties
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.
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
A regular expression for validation of tokens before the Lambda function is called.
