Event catalog

Every webhook event the integration emits, what it means, and the shape of data.object. The envelope wrapping each payload is documented on the Webhooks page.

Subscribing to events

Subscriptions are managed from Custom Integration → Settings → Event subscriptions. The default is the wildcard *: your endpoint receives every event.

Tick individual events to allowlist them.
Wildcard a namespace with e.g. listing.* (subscribe to all listing events).
integration.test_event ignores subscriptions; it's always delivered when fired manually.

Echo-suppression

Don't expect to receive your own writes back

When your integration POSTs an order via /v1/orders, the corresponding order.received webhook is not delivered to your URL. Same for customer.matched: the integration that did the upsert doesn't hear about its own match. This is what stops trivial event-loops between your custom site and WatchTraderHub.

Events triggered elsewhere (other integrations like Shopify or eBay, actions taken in the dashboard) still fire to your URL as normal.
