API Docs
Everything you need to build on top of the platform.
A REST API and signed webhooks give you programmatic access to conversations, contacts, campaigns and payments — so you can build custom integrations, sync data with your own systems, or automate workflows we don't support natively.
- REST API for contacts, conversations, campaigns and payments
- Signed webhooks for real-time event delivery
- API keys managed per business from your account settings
Authentication
Every request is authenticated with an API key generated from your account settings. Keep it secret — it has the same access as your account.
Core resources
The API is organized around the objects you already work with in the app.
- Contacts — create, update, tag and search your contact list
- Conversations & Messages — send messages, read history, manage assignment
- Campaigns — trigger broadcasts and read delivery status
- Payments — create invoices and payment links, read transaction status
