Verification API Documentation

The API has been deprecated. Looking to build a one-time phone verification? Use our Number Verification API instead for a more flexible solution

You can use Messente's HTTP SMS API to verify your client's phone number

Messente has lots of ready-made libraries for easy integration - go and check out Messente API Libraries.

How to Verify client's phone number with Messente
