React when social work changes.

Subscribe your backend to publishing, approval, inbox, and workflow events instead of polling the API.

Create a subscription

cURLCopy and customize

curl -sS "https://app.postzivo.com/api/public/v1/webhooks" \
  -X POST \
  -H "Authorization: Bearer $POSTZIVO_API_KEY" \
  -H "Idempotency-Key: webhook-001" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://example.com/webhooks/postzivo",
    "events": ["post.published", "post.failed", "approval.updated"]
  }'

Delivery rules

Return a successful 2xx response quickly and process work asynchronously.
Deduplicate events by delivery or event identifier.
Expect retries after timeouts and non-success responses.
Do not assume events arrive in the same order that changes occurred.
Log the request identifier and event type for investigation.

Verify every delivery.
Use the signing secret provided when the subscription is created. Reject requests with an invalid signature or stale timestamp.
