SMS Verify API

TeleSign’s SMS Verify API is specifically designed to deliver one-time passcodes (OTPs) securely.

You can use the SMS Verify API to send regular messages, but TeleSign does not recommend this. Instead, you should use TeleSign’s SMS API, which is designed with general SMS messages in mind.

The use case for SMS Verify is:

  • Send an OTP using SMS -
  • Buy a Sender ID -
    • Phone Numbers API - Purchase a phone number to use as a Sender ID using the Phone Numbers API.
  • Use SMPP -
    • SMPP - Use broad character sets and deliver different message encodings to handsets for global operations (GSM7, Latin1, and various Unicode encodings). Send messaging requests via Short Message Peer-to-Peer (SMPP) protocol to ensure highj throughput and interoperability with your SMPP Short Message Entities (SME/ESME).
