This might be obvious and stupid but can I use JWT authorizer with my custom jwt implementation? Like I have my custom signup / signin endpoint that generates the token. Could someone verify if this will work or will I need to use Lambda authorizers to implement this?

This should 100% work. You can use Lambda authorizers to intercept requests on an ApiGateway and validate your JWTs: https://docs.aws.amazon.com/apigateway/latest/developerguide/apigateway-use-lambda-authorizer.html Here's a blog post that might be of interest if you're looking for more detail about how to decode/validate tokens. It uses Auth0 as the token broker but it breaks down the overview flow well enough to roll your own: https://levelup.gitconnected.com/creating-a-simple-serverless-application-using-typescript-and-aws-part-2-2f9192717015

@Ashishkumar Pandey i haven’t done this, but I’m assuming the JWTAuthorizer just makes an api call to a endpoint under the JWT domain to validate the token behind the scene.

yes, working on it, creating a custom jwks, will update here. if this works, this would be a much better solution than lambda authorizers.
