There are three API calls :
- Verification Request : provide the number to be verified and Nexmo will send back a Verification Request ID for future reference. Some requests might be rejected outright (e.g. invalid numbers or parameters).
- Verification Check : provide the PIN code obtained from your end user along with the Request ID in order to know whether it matches the PIN code Nexmo Verify sent to the end user.
- Verification Search : look up one or multiple requests in order to know their status (In progress, Successful, Failed or Expired) and many other attributes.
