What you can do with the REST API integration
Build any custom integration with the Whautomate REST API. Sync clients, manage contacts, send messages, trigger broadcasts, book appointments, run classes and orchestrate every part of the platform programmatically. Full reference is available in the Whautomate REST API help guide.
The API is REST + JSON and authenticated with an API key. Whautomate is hosted in multiple regions, so data stays in the geography that matches your account - the right base URL is shown inside Integrations → REST API in your dashboard, no need to memorise it.
Use the REST API to wire Whautomate into your product, internal CRM, data warehouse or AI agent. If you would rather build with no code, the same actions are available through the Zapier, Pabbly Connect, Pipedream, viaSocket and n8n integrations - all built on top of this API.
