API Authentication

Hi,

together with one of our customers we want to share data from Microsoft NAV to MS CRM (both on-premise).

Now we're struggling with the authentication. From an C# application this part is no problem, using the Microsoft SDK and tooling classes, and is as easy as:

using (var client = new CrmServiceClient(new NetworkCredential(/<Username>/, /<Password>/, /<Domain>/), /<Base-Url>/, //, /<Org>/, useSsl: true)){    if (client.IsReady)    {        var who = client.Execute(new WhoAmIRequest());    }}

How would we go about it without SDK/tooling? Let's say if we tried with HttpClient or from JS or something else, would that be possible?

We're using ADFS, so I guess Basic Authentication (as described here: Authenticate to Dynamics 365 Customer Engagement with the Web API (Developer Guide for Dynamics 365 Customer Engagement) | Microsoft Learn) is not possible? At least our tests were not successful.

Most examples I come about are mentioning a clientId, but the SDK-example doesn't use one either, so I think I'm missing something?

If anyone has an idea or working example, please let me know.
