This guide shows how to verify a user in a PHP application using the Verification API to make an SMS PIN verification.
The following diagram demonstrates the flow that happens to verify a user:
- The end user visits your website or service and tries to log in.
- Your backend then makes a request to the Sinch platform and initiates an SMS PIN verification request.
- The Sinch platform sends an SMS message with a one time PIN code to the phone number of the user.
- The user enters the code they received.
- Your backend makes a report verification request using the code the user entered.
- If the code matches, your backend will receive a success result from Sinch.
- The user, now verified, can proceed to log in to your site or service.
Now you're ready to get started by initiating a verification request.
