Welcome to the Tanvik API
Tanvik’s API lets you send WhatsApp messages, verify customers with OTP, manage templates, and receive real-time events — all from your own backend.Quickstart
Send your first message in a few minutes.
Authentication
Generate and use your API key.
Send OTP
Verify customers with a WhatsApp one-time password.
Webhooks
Get notified in real time as things happen.
What you can build
- OTP verification — send and verify one-time passwords for login, checkout, or KYC flows.
- Transactional messaging — order confirmations, shipping updates, and reminders via approved templates.
- Small-batch broadcasts — send an approved template to up to 100 recipients in one call, with per-recipient delivery results.
- Two-way conversations — reply to customers within the 24-hour session window and receive their messages via webhook.
- Real-time events — subscribe to message delivery, OTP verification, and template approval events instead of polling.
