I am using an AWS proxy ApiGateway that is mapped to a lambda function that is hosting a REST Api. Everything is wired up and functioning, except I see that responses from the server are remapping my 'Authorization' header to 'x-amzn-remapped-authorization', which is causing problems for web clients that are looking for the 'Authorization' key in the response headers.

I picked a proxy integration setup because I don't want Amazon to do anything special, just serve requests. I realize that I could tell the clients to read the remapped key, but that is bending to accomidate Amazon's 'decision'. I think I have correctly set CORS to properly expose the Authorization header, and I have the 'Lambda proxy integration' option turned on in the Api gateway. Is something I am missing to disable this remapping?

    Authorization is a request header, you shouldn't have it in your responses anyway? Commented Apr 10 at 0:22
  • Authorization is indeed a header that should appear in responses, as I explicitly add it in code with a bearer token as a value. However, when it apprives at the client, it has been renamed 'x-amzn-remapped-authorization'. That is the problem that I am trying to fix. Commented Apr 10 at 0:53
  • So you're aware that you're using it in a non-standard way? Commented Apr 10 at 8:31
  • How is this non-standard? Authorization headers are a very common method to pass tokens around. I am trying to do this in the most standard way possible. Commented Apr 10 at 17:30

    Authorization headers on requests, yes. On responses, no. Commented Apr 10 at 17:31
