Start integrating with the WATI API for messaging, contacts, automation, and workspace operations.
Wati is the ultimate WhatsApp management tool for your business.
By providing the following key features, Wati enables your team to:
- Connect with customers in real-time without sharing devices or switching tools
- Access 2 Billion+ WhatsApp users
- Send broadcasts via WhatsApp to targeted customers
- Manage concurrent customer messages with a unified inbox
- Get data-driven insights
Please keep in mind that the APIs described in this doc complement the use of the Wati user interface.
API versions
WATI offers two API versions:
- API V3 (recommended) — Use this for all new integrations. Endpoints use the
/api/ext/v3/...path. - API V1 (legacy) — The older API, still available but not recommended for new projects. Some endpoints in this spec use an
/api/v2/...path — these are updated variants within V1, not a separate API version.
Both versions are documented in the sidebar under their respective sections.
API base URL and tenant routing
Use https://live-mt-server.wati.io as the API host.
- V3:
https://live-mt-server.wati.io/api/ext/v3/...— do not add a tenant ID to the path. - Legacy V1/V2:
https://live-mt-server.wati.io/{tenantId}/api/v1/...orhttps://live-mt-server.wati.io/{tenantId}/api/v2/...— replace{tenantId}with your WATI workspace (tenant) ID.
tenantId identifies the WATI workspace for a legacy request; it is not a phone number. Each legacy endpoint declares it as a required path parameter.
The WATI navigation bar contains the following tabs:
- Dashboard: displays real-time statistical information.
- Broadcast: schedule, trigger and monitor broadcast template messages.
- Contacts: list of contacts and contact management (add, remove, update existing contacts).
- Team Inbox: collaboration on chats.
- Automation: Set up some keywords for a bot to auto-reply, and set up some rules to trigger template messages eg: non-office hours, expired, waiting, etc.
Group Demo
The Wati team delivers a group demo twice a week. Please feel free to attend them if you are looking to integrate WhatsApp/WATI with your own system using APIs and Webhooks.
