The Watermelon API lets you connect your own systems directly with Watermelon to manage contacts, conversations, and webhooks automatically. It’s built for developers who want to extend their workflows, synchronize data, or create custom experiences on top of Watermelon.

​
What You Can Do

  • Contacts: Create, search, update, and retrieve contact information, including custom fields.
  • Messaging: Fetch conversations or messages, send new ones, and build your own messaging layer powered by Watermelon.
Webhooks: Set up automated notifications for key events, such as when a new contact is created or a message is received.

​
Example Use Cases

  • Connect your CRM to automatically sync contact and conversation data.
  • Build a live dashboard that displays ongoing conversations in real time.
  • Trigger external workflows when new messages or contacts appear in Watermelon.
The API uses standard REST methods (GET, POST, PUT, DELETE) and returns clean, predictable JSON responses, making integration simple and reliable.
