[keycloak-user] Using Keycloak to secure AWS API Gateway Lambda endpoints

Hello everyone, We'd like to use Keycloak in our new API managed by AWS Lambda / API Gateway. Unfortunatly, we didn't find an adapter for AWS API Gateway / Lambda. So we decided to write an adapter that consists of 2 lambdas : 1/ A Lambda that validates the JWT, and in case of a new public key, requests the Keycloak to get the new public key. This lambda is used as an Authorizer. 2/ A Lambda that deals with revocations. It exposes an endpoint (k_push_not_before) in order to receive Admin Not Before Policy Pushes. What do you think of this solution, your feedback and experiences on Keyckoak and AWS Gateway / Lambda are welcome. Regards, Youcef
