Base only reacts to changes when you explicitly configure it to. That’s what Automatic Actions are for — “IF X happens, THEN do Y” rules configured directly in the Base panel (both generally and within specific integration settings, e.g. Integrations → Allegro → Order Statuses).

Three ways to catch a change on an order

  1. An Automatic Action in Base — e.g. “if a cancellation request arrives from the marketplace, set status to Cancelled.” The simplest to maintain, since it runs entirely on Base’s side and needs no extra logic in your system.
  2. Polling getJournalList — returns a list of order events from the last 3 days, including confirmation and cancellation. Disabled by default; enable it in the Base panel under Profile → API.
  3. A webhook — a “Call URL” action in Automatic Actions. Base calls your defined URL the moment the watched event occurs, passing the order ID and optionally extra parameters (e.g. &cancel=1) or values pulled directly from the order (similar to what’s available in email templates). Usually the fastest way to catch an event in real time without polling.

Most common use case: catching a cancellation

A customer requests to cancel an order on a marketplace → Base knows about it → you need to find out before you ship the order unnecessarily. The solution is a combination of the above: either an Automatic Action directly sets status Cancelled/Rejected (see the specific rules in Statuses), or a webhook notifies you, or you notice it during a regular getJournalList poll.

Delivering tracking numbers and invoices to the marketplace

Forwarding a tracking number or invoice to the order source is often tied to a specific status and isn’t instant — Base processes it in batches, typically around 9:00, 10:00, 13:00, 16:00, and 23:00 (± a few minutes). For Alza integrations, the cut-off time (COT) setting also plays a role. Details in Shipping labels and Invoices.
For new integrations, we recommend combining webhooks (for fast reaction to critical events like cancellations) with regular getOrders/getJournalList polling as a safety net in case a webhook fails for some reason.
