Connect a number by scanning a QR code, then send and receive messages through a REST API and signed webhooks — no Business Platform approval process.
curl -X POST https://app.tarceel.com/instances/<instanceId>/messages/text \
-H "Authorization: Bearer sk_..." \
-H "Content-Type: application/json" \
-d '{"to": "15551234567", "text": "Hello from Tarceel!"}'
Text, media, location, and contact cards over a plain REST API — no WhatsApp Business template review to wait on.
Every inbound message and status change is signed (HMAC-SHA256) and retried with backoff, with a manual redrive if you need it.
A flat monthly/yearly plan per number, or prepaid credits that never expire — switch between them any time.
