I'm using xamarin forms to develop my android app. I'm done with sending data as POST requests now.
I'm currently using GSM Modem (SMS) as a placeholder for other SMS APIs for OTPs in the future. This is the URL that the app gives me:
Received URL
As you can see, there are parameters available. Using my browser/PHP, I can easily refresh the page with new values in the parameters. However, in C# I'm quite unfamiliar with filling up these parameters.
I just want my app to send a signal or something to the URL with a dynamic phone and message parameters.
