Migrating from Twilio

Moving an existing Twilio WhatsApp integration over is mostly a matter of swapping the request shape — the underlying concepts (sessions, message sends, webhooks) map directly.

1. Pair a number instead of provisioning a Twilio sender

Twilio requires WhatsApp Business Account approval before you can send. Here, create a session via POST /v1/sessions and scan the QR code (or use a pairing code) — no approval wait.

2. Replace messages.create()

Twilio's SDK call becomes a plain REST call. No pre-approved message templates are required for session (non-template) messages.

POST /v1/sendText
{ "chatId": "1234567890", "text": "Hello!", "session": "default" }

3. Swap the status callback for a webhook

Twilio's statusCallback URL becomes a webhook registered via POST /v1/sessions/{session}/webhooks. Subscribe to message.ack for delivery/read receipts.

4. Run both in parallel during cutover

Keep the Twilio number live and route a small percentage of new conversations through the new session first. Once delivery and webhook data look correct, cut fully over and release the Twilio number.
