LambdaAuthorizerConfig

A LambdaAuthorizerConfig specifies how to authorize AWS AppSync API access when using the AWS_LAMBDA authorizer mode. Be aware that an AWS AppSync API can have only one AWS Lambda authorizer configured at a time.

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 AWS Command Line Interface (AWS 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

Type: String

Required: Yes

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.

Type: Integer

Valid Range: Minimum value of 0. Maximum value of 3600.

Required: No

identityValidationExpression

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

Type: String

Required: No
