Real-time SMS webhooks that push delivery receipts, inbound replies and status events straight into your application as they happen.
The icpaas.ai SMS Webhook Integration Engine turns every message event into an instant, structured callback to your own endpoint. Delivery receipts, failures, inbound replies and DLT status changes are posted as clean JSON the moment they occur, so your application always reflects the true state of each SMS without polling, manual reconciliation or guesswork across high-volume campaigns.
Built by a TRAI/DLT-registered provider serving India since 2015, the engine pairs direct operator connectivity with signed, retried and ordered webhook delivery. You configure endpoints per route, secure them with secrets, and receive events for promotional, transactional and OTP traffic. With 99.9% uptime and over 10M messages handled daily, your callbacks stay reliable even at peak scale.
Receive DLR callbacks the instant operators confirm delivery or failure, keeping your message state perfectly accurate at all times.
Capture two-way responses on longcodes and shortcodes, posting sender, keyword and message content straight to your endpoint.
Every webhook carries a signature and shared secret so your servers can verify authenticity and reject any spoofed requests.
Failed callbacks retry with backoff and preserve event order, so transient outages never lose a single delivery status.
Subscribe specific endpoints to OTP, transactional or promotional events and filter by status to cut callback noise.
Get callbacks for DND scrubbing, template rejections and header status so compliance issues surface immediately, not later.
Draft message copy and DLT headers matching entity profiles.
Integrate transactional triggers inside website checkout steps.
Set up secondary gateway routes for guaranteed failover delivery.
