There might be another way to solve my problem, so if there is please advise. Currently I have a Blazor application with a WASM frontend and a server hosting with my API endpoints on the backend. Seeing as these are in the same VS solution, I have created a Endpoints class to maintain all of my base routes.
For example:

public static class Endpoints 
{
    public const string Route1 = "/api/v1/MyRoute";
    public const string Route2 = "/api/v1/MyOtherRoute";
}

These base endpoints are then used as the base to defining my routes within Refit and the endpoints on the server. However, I would like to use Api Versioning which as far as I can tell, the route needs to have v1 replaced with v{version:apiVersion}. While this works for the serve routes, Refit complains about not having a matching parameter in its argument list.

If my approach is incorrect let me know. If this approach is valid, then it would be nice to be able to specify a setting in Refit that prevents the runtime from throwing when a parameter does not match in the argument list. This way I can replace the unused parameter myself inside a delegating handler.

Alternatively, it would also work if I could specify a parameter in the route, and have it replaced by an attribute, as opposed to an argument.

I think the easiest solution would be to add a setting to the RefitSettings, that prevents an exception from being thrown when not all parameters are matched.
