Delivery

Transyt’s delivery system ensures webhooks reach your application reliably, with automatic retries and failure handling.

Overview

When an event is ingested and a delivery_url is configured, Transyt:

1. Immediately attempts delivery via HTTP POST
2. Signs the request with HMAC-SHA256 (X-Gateway-Signature)
3. Waits for a 2xx response (30-second timeout)
4. On failure, schedules a retry with exponential backoff
5. After 10 failed attempts, marks the event as failed and triggers destinations

Key Parameters

Parameter	Value
Maximum attempts	10
