Send your first webhook event

Webhooks are how Releaseo talks to the rest of your stack — your own API, Zapier, Make, n8n, you name it.

Add a destination

Settings → Integrations → Webhooks → New webhook.

• URL. Your HTTPS endpoint.

• Events. Pick what to send. Start with post.published only.

• Signing secret. We generate one for you — store it on your end.

A test fires immediately

The moment you save, Releaseo sends a webhook.test event with a sample payload so you can verify your endpoint.

The event envelope

{
  "id": "evt_…",
  "type": "post.published",
  "createdAt": "2026-05-27T12:00:00.000Z",
  "projectId": "PM-…",
  "data": { "…": "…" }
}

Every event is signed with your secret in the X-Releaseo-Signature header. Verify it on your side to confirm the event is real.

Retries

If your endpoint returns a non-2xx, Releaseo retries up to 6 times with exponential backoff over ~24 hours.
