WhatsApp & SMS (One API)

If you still use our WhatsApp RESTful API, see the relevant section in our Archive. All new WhatsApp integrations will be done via Clickatell's One API.

Why use this API?

One API enables you to communicate with your mobile customers on multiple messaging channels with a single integration. Use One API to send and receive messages on both WhatsApp and SMS without the overhead of programming individual channels.

One API also makes your implementation future-proof as we add support for additional channels to the Clickatell Platform.
