How the Verify API works
Verify uses two API endpoints to seamlessly check that a user is the owner of the phone number they provide.
The start API endpoint
When the user is validating their phone number, Verify sends the user a 4-10 digit verification code via SMS or Voice and waits for their response.
The check API endpoint
Verify checks the user’s input matches the code. If they match, Verify registers the phone number as approved.
Integration was extremely fast, it was a nice surprise. We aren't used to being able to integrate with a third-party so easily.
