Pass a header paramter / value for each vector tiles request

Hi,

I am adding vector tiles support using your maps in MAUI app. What I can't pass through is that each request to our server requires additional header value with our token in order to get response.

For that I was using different map provider and I had interceptor service that was adding for each call from my BE endpoint header as:

request.Headers.Add(_tokenHeader, _token);

Now I was thinking about using

AuthenticationManager.Current.ChallengeHandler = new ChallengeHandler(ChallengeMethod);
but I am worried there's no option to setup it like that.

Can you suggest solution or it's not possible to inject header into request?

You can use the ArcGISHttpClientHandler.HttpRequestBegin event to listen for and modify requests.

ArcGISHttpClientHandler.HttpRequestBegin += (sender, message) => { if (message.RequestUri.Host == "www.myhost.com") { message.Headers.Add("MyTokenHeader", "MyToken"); } };

So that's what I did. Handler seems to trigger correct url.
This is still my result:

[0:] Accessing https://myurl.com requires authorization. Set a ChallengeHandler to provide credentials.
