Store dashboards are built for sessions, not for glances. If you run a shop alongside anything else, the first you hear of an order is usually a confirmation email buried under the rest of them.
Order events are the most satisfying webhooks to route to a phone, and the most useful: a cancellation or a failed fulfilment is something you want to catch before the customer chases you about it.
The one you will actually enjoy receiving. Order value in the title.
Worth knowing immediately, particularly if fulfilment has already started.
The quiet failure that turns into a support ticket three days later.
Same logic as payments: better from your phone than from an angry email.
Each of these sends the events above. Setup is the same for all of them.
