How does the Verify API work for SMS?

It sends time-sensitive codes via SMS to authenticate users during login, registration, or transactions using our secure text SMS API.

Integrate Seamlessly

The user initiates SMS verification within your app by providing a phone number or opting for SMS verification.

Request to TopMessage:

Your app sends a request to TopMessage to verify the user's phone number.

OTP Generation:

TopMessage generates a one-time password (OTP) upon successfully validating the phone number.

SMS Sent:

TopMessage sends an SMS to the user's registered phone number containing a one-time code. The user inputs this code back to TopMessage for verification.

TopMessage verifies that the entered OTP matches the one generated by their system. If the codes do not match, the verification process is incomplete, ensuring secure and accurate user authentication through SMS.
