The Verify API allows you to send a PIN by SMS and phone to prove a user can be contacted at a specific phone number.

This is useful for:

  1. Spam protection - prevent spammers from mass-creating new accounts (etc.)
  2. Hack protection - if you detect suspicious or significant activities, validate that the person using a phone number owns it
  3. Two-factor authentication
  4. Reaching users - ensuring you have the correct phone number makes it easy to contact users when you need to

By default, the PIN is first sent via text message (SMS). If there is no reply the Verify API will then try a voice call using text-to-speech (TTS).
