How is a user provided apiKey sent to a custom endpoint

[keviddles]

I've set up a custom endpoint that contains a hard coded API key.

I've now updated the API key to be user provided:

      apiKey: "user_provided"

Which displays the UI correctly. However, I don't see the key being passed in librechat's requests to my custom endpoint, nor can I find any documentation (i.e., here) about how it's forwarded.

Specific questions:

• How is a user provided API key passed to the custom endpoint? Does it come in the header or in the body?
• What's the name of the key? apiKey?

Thanks!

The answer is that it is passed as a header under Authorization.

I'm using FastAPI, and to get it from the Request I can do:

authorization = request.headers.get('Authorization')
