A webhook is a Heyoo address another system calls when something happens: an order paid in the shop, an appointment booked, an invoice overdue.
What you can see on a phone
- Endpoints registered and whether they are active.
- Activity — the latest events received.
- Failures — what arrived and was not accepted.
- Automations linked to each webhook.



It is the diagnosis screenWhen someone says the integration stopped, the activity answers in seconds: the event never arrived (a problem on the other side), it arrived and failed (the reason is right there), or it was accepted (the problem is further down).
Switching on and off
An inactive endpoint loses eventsEvents received while the webhook is switched off are rejected, not queued. Whatever happens during that window is not recovered later.
What requires the computer
Creating the endpoint, copying the URL into the other system and building the automation's action flow.
