Question

The documentation is unclear how InvokeRESTAPI authenticates to the server it's sending a request to. Generic service credentials have separate username and password fields, but neither the credential nor InvokeRESTAPI specify whether they will always be used with HTTP Basic authentication, or if there's any way to use the Bearer scheme, or something else.

I looked up the InvokeRESTAPI task but found there's no actual code here, just a HttpRequest block since it's a server side task. Then I found the server side task authoring documentation, but it says only:

EndpointId: - EndpointId that should be used to generate the authentication header.

The documentation should specify exactly how authentication is handled, even if the answer is, "Only HTTP Basic authentication is supported".
