LambdaAuthorizerConfig

import type { LambdaAuthorizerConfig } from "https://aws-api.deno.dev/v0.3/services/appsync.ts?docs=full";

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

interface LambdaAuthorizerConfig {

authorizerResultTtlInSeconds?: number | null;

authorizerUri: string;

identityValidationExpression?: string | null;

}

§Properties

authorizerResultTtlInSeconds?: number | null

[src]

The number of seconds a response should be cached for. The default is 5 minutes (300 seconds). The Lambda function can override this by returning a ttlOverride key in its response. A value of 0 disables caching of responses.

authorizerUri: string

[src]

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?: string | null

[src]

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