SMS-enable your website or application with Clickatell’s API set and send messages through any USA operator or worldwide.
We’ve gone to great lengths to ensure any developer who wants to interface an application, site or system with our messaging gateway can do so reliably and simply.
Our APIs are fast, simple and reliable, and built in such a way that they are easily manipulated to fit with any system. And with our quick online registration you are able to get started and use them right away.
Clickatell’s easy to use API’s are embedded in its Small Business API, giving you immediate access to any mobile operator in the Americas region or in its Global SMS Gateway for worldwide coverage.

SMPP API Our most robust connection, suitable for customers who send large volumes of traffic. Clickatell offers a global SMPP connection using the SMPP 3.3 and 3.4 standard. Customers are required to have SMPP client software in place, and unlike our other APIs there are minimum volume requirements when using SMPP. Sign up
