Communication between app and service

[josenunes]

Hello, greetings to all.

I have a question about how can communication between different entities be done.
So, I would have a button in my app that uses Application.OpenExternalURL - this would work well in any of my supported platforms - windows, mac, webgl, ios and android.

This external URL would be some kind of Single Sign On that would give an auth token back to the app. I know that in windows it is possible to implement some command arguments, but on app initialization.

I’ve also considered embedding a web browser in the app but that wouldn’t work I think.
Is there a way to achieve this with some kind of external / internal notification / communication system?
Thanks in advance

I think it would just be a series of REST calls to get the token(s) you need.

There are also some OAuth2 packages on the asset store that might be helpful.

Whatever it is, if you run into issues, this approach may be useful:

Networking, UnityWebRequest, WWW, Postman, curl, WebAPI, etc:

As with all network code, get it working with Postman or curl first. That makes it NOT a Unity problem. Solve the networking first. You must solve that or anything else is irrelevant. Once you have that working, then try and port it to UnityWebRequest. If it still doesn't work, one handy debug solution is to hook up a proxy like Charles and compare the functioning output from Postman / curl to the output from Unity, and from that reason about where your issues are.

Unity web request acting stupid.

Always get network stuff working outside of Unity in either curl or PostMan, then connect a proxy such as Charles and start trying to replicate the traffic shape with UnityWebRequest. Any other way risks wasting a lot of your time for trivial issues that only the above way will instantly reveal.

And setting up a proxy can be very helpful too, in order to compare traffic:
