Webhooks

Get a signed HTTP callback the moment an email is sent, opened, clicked, or replied to, a sequence finishes, or a contact unsubscribes — build your own automation on top without polling the API.

How it works

You register an endpoint URL and choose which events to receive. On each matching event, Sendqube POSTs a signed JSON payload — with an HMAC signature header — to your URL, retrying automatically if your endpoint is briefly down.

The process in Sendqube

  1. 1Go to Settings → Webhooks and add an endpoint URL.
  2. 2Choose which events to subscribe to (sent, opened, clicked, replied, sequence finished, unsubscribed).
  3. 3Verify the signature on your end using the shared secret, then build automation on top without polling.
