(AppSync): Add support for custom authorization with AWS Lambda for GraphQL APIs

[ohnu]

Description

Since July 2021 there is a new authorization type introduced for GraphQL APIs https://aws.amazon.com/about-aws/whats-new/2021/07/aws-appsync-supports-custom-authorization-with-aws-lambda-graphsql-apis/
and is not exposed by the latest CDK release v1.126.0 https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-appsync.AuthorizationType.html

Use Case

We want to create our own authorization lambda (that we already use in the REST api) but is not available in the GraphQL API.

Proposed Solution

general Idea:

Include an authorization type LAMBDA in AuthorizationType
also include a lambdaConfig property in AuthorizationMode in order to provide the lambda arn
