Webhook delivery you can trust
How Reachase handles retries, signatures, and delivery logs for production integrations.
Maya Okonkwo · Engineering
Webhooks are only useful if they arrive. When a customer submits a form or books a meeting, your CRM, Slack workspace, or internal database needs that event reliably.
Webhooks get the same attention as the REST API. Retries, signatures, and delivery logs ship together.
Signed payloads
Every webhook includes a Reachase-Signature header with an HMAC SHA-256 digest of the raw body. Verify signatures before processing events to prevent spoofed requests.
Signing secrets are unique per endpoint and can be rotated from the dashboard without downtime.
Retries and backoff
If your endpoint returns anything outside the 2xx range, Reachase retries with exponential backoff for up to 72 hours. Transient outages should not mean lost submissions.
- Delivery attempts are logged with response codes and latency.
- Failed events can be manually retried from the dashboard.
- Dead-letter state is visible so nothing disappears silently.
Operational visibility
Production integrations fail in predictable ways: deploys, rate limits, bad deploy configs. The webhooks page in the dashboard shows recent deliveries, failure reasons, and payload previews so you can debug without digging through server logs.
