Developer API

Send messages from your own systems, with the same rules as the console

Message

Send from where the event happens

Order confirmations, payment receipts, one-time codes and appointment reminders are triggered by your own systems. The developer API lets those systems send the message directly, the moment the event happens, without anyone copying it into a console.

WhatsApp templates and messages
SMS from your approved sender ID
Email from your verified domain

API keys you control

Create an API key for each system that sends, and keep it on your server. Requests made with it act for your business, with the same templates, prices and sending rules as the console.

Webhooks for what happens next

A message being accepted is only the start. Webhooks tell your system when a message is delivered or fails, and when a customer sends a message in, so your own records stay up to date without polling.

One set of rules for every caller

A message sent by API and a message sent from the console go through the same checks: opt-outs, template approval and wallet balance. Your developers do not have to rebuild those rules, and your team does not have to wonder whether the API behaves differently.

Questions people ask

Which channels can I send through the API?

WhatsApp templates and messages, SMS and email.

Do I still need approved WhatsApp templates?

Yes. WhatsApp's rules apply to API sends too: a template to start a conversation, free-form replies inside the 24-hour window.

How do I receive customer replies?

Set up an inbound webhook, and each message a customer sends is posted to your endpoint.

How is API usage charged?

The same way as the console: each message is priced by country and category and paid from your wallet. There is no separate API fee.
