The events
There are nine events, in three groups. The technical name in the second column is what your system receives.

Select all ticks every event, including Tracking updated
Orders that come in from a connected webshop, and the changes the webshop sends later, don’t send order events. Your system still hears about them through the shipment events: Zippendo creates a shipment for each order it imports.
Send test sends a test message called
webhook.test. You can’t tick it as an event.
Edit or pause a webhook
Click the row, or Edit, to open Edit webhook. It has the same fields as Create webhook, plus Active. Click Save changes when you are done.

Edit webhook: the same fields, plus Active
Delivery log
Delivery log on a row shows the latest attempts to deliver to that address.

Delivery log: event, status, duration, attempt, error and time
Zippendo waits up to 10 seconds for your server to answer. If it doesn’t answer, or answers with an error, Zippendo tries again, up to 5 times in total, waiting a little longer each time. Every try is a row in the log.
Send a test message
Click Send test on a row. You see Test event sent. The test message looks like this:Delete a webhook
Click Delete on a row. Delete webhook asks you to type the webhook’s name in capital letters, then click Delete. The webhook and its Delivery log are removed, and you see Webhook deleted.

Delete webhook: type the name in capital letters to confirm
For developers: message format and signature
Every message is aPOST with a JSON body { "event", "timestamp", "brandId", "data" } and these headers:
Zippendo creates the secret when you create the webhook. The app does not show it: read it with the Get webhook request in the API reference (the list request leaves it out). Check the signature before you read the body. A worked example is in the Webhooks quickstart. Orders pushed into a custom order channel are signed the same way, with an
X-Zippendo-Signature header: Custom channel API.
