What is the difference between Verify and other Nexmo APIs such as SMS and TTS?


Nexmo Verify enables you to establish whether one of your end users has access to a specific phone number through testing with a PIN code to enter into their application or website. That PIN code is sent by Nexmo via SMS and/or TTS (Text-To-Speech call).

Nexmo Verify hides all the complexity and takes care of :

  • Delivering verification messages and calls
  • Failover management using the optimal workflow (sequence and timing of attempts) across Voice- TTS (Text-To-Speech) and SMS
  • PIN generation and expiration handling
  • Template management : localised in 23 languages for SMS and TTS and optimise, depending on the delivery method
  • Simple pay per conversion and pricing

Alternatively, you are able to utilise our SMS and TTS API's but you will need to build, maintain and manage the above capabilities.
