Description

Description

Looking at the endpoints generated from the api.mustache template, there doesn't seem to be a way of passing custom HTTP headers as part of a request. The plan is to modify the mustache template by adding an optional parameter for specifying custom headers when making an API call.

Additional context

Adding this functionality to the C# API template will bring it in line with other language client generators, e.g. the python-legacy one, which already has this feature.

Research direction

Start with the api.mustache template used for generated C# endpoints and compare the existing custom-header support in the linked python-legacy change. Define the optional custom-headers parameter for API calls, then verify that generated C# clients can pass those headers without affecting calls that omit it.
