What is SMS API?

An SMS API allows you to send SMS messages using code. You can trigger messages to your customers on autopilot based on predetermined conditions. For example, the predetermined condition for payment requests trigger is sending out an OTP for verification.

The service provider, Exotel’s SMS API acts as the middleman between the trigger and the response. The API facilitates the built-in condition and its response by operating between them.
