How Titan works

1

Create a session

Create a named session for each WhatsApp number you want to connect.
2

Pair your number

Scan a QR code or enter an 8-digit pairing code to link the number to Titan.
3

Send messages and receive events

Call POST /api/messages/send to send messages. Configure webhooks to receive incoming messages, delivery receipts, and other events.
4

Automate with SDKs

Use the official TypeScript, Go, Python, or PHP SDK to build your integration with typed clients and built-in webhook verification.
Titan supports both a managed SaaS edition (no infrastructure to run) and a self-hosted edition for teams that need full control. See Self-Hosting for deployment options.
