AuthorizerResultTtlInSeconds = 123,

};
Synopsis
Properties
AuthorizerResultTtlInSeconds | The number of seconds a response should be cached for. |
AuthorizerUri | The ARN of the Lambda function to be called for authorization. |
IdentityValidationExpression | A regular expression for validation of tokens before the Lambda function is called. |
Properties
AuthorizerResultTtlInSeconds
The number of seconds a response should be cached for.
virtual Nullable<double> AuthorizerResultTtlInSeconds { get; }
Property Value
System.Nullable<System.Double>
Remarks
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
The ARN of the Lambda function to be called for authorization.
virtual string AuthorizerUri { get; }
Property Value
System.String
Remarks
This may be a standard Lambda ARN, a version ARN ( .../v3
) or 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 do so with the 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
IdentityValidationExpression
A regular expression for validation of tokens before the Lambda function is called.
virtual string IdentityValidationExpression { get; }
Property Value
System.String
