Verify a user using SMS PIN with ASP.NET Core 6.0

This guide shows how to verify a user in an ASP.NET Core 6.0 application using the Verification API to make an SMS PIN verification.

The following diagram demonstrates the flow that happens to verify a user:

1. The end user visits your website or service and tries to log in.
2. Your backend then makes a request to the Sinch platform and initiates an SMS PIN verification request.
3. The Sinch platform sends an SMS message with a one time PIN code to the phone number of the user.
4. The user enters the code they received.
5. Your backend makes a report verification request using the code the user entered.
6. If the code matches, your backend will receive a success result from Sinch.
7. The user, now verified, can proceed to log in to your site or service.
