Built for Developers
If native CRM integrations aren't enough, IQ NumberHub provides a robust webhook engine that allows you to build completely custom routing logic. Whenever an event occurs on your numbers—like an inbound SMS, a delivery status update, or an incoming call—we instantly fire a POST request to the URL of your choosing.
Real-time Event Triggers
message.received- Triggered when a new inbound SMS arrives.message.delivered- Triggered when the carrier confirms delivery.message.failed- Triggered if a message bounces or is blocked by spam filters.call.incoming- Triggered the moment a number is dialed.
Reliable and Scalable
Our webhook infrastructure is designed to handle massive throughput. Whether you are receiving 10 messages a day or 10,000 messages a minute, our queueing system ensures that your endpoint receives the payload.
- Automatic Retries: If your server returns a 5xx error or times out, we utilize an exponential backoff strategy to retry the webhook delivery.
- Payload Verification: Secure your endpoints using our HMAC-SHA256 signature verification to guarantee that incoming requests genuinely originated from IQ NumberHub.
Debugging Made Easy
The IQ NumberHub dashboard includes a live webhook inspector. View the exact JSON payloads, headers, and response codes of recent webhook events to rapidly debug your integration.
