To **use webhooks to react to events**, you let the platform tell your system something happened rather than asking it repeatedly. The direction is the whole point.

## What polling costs

Checking for change is wasteful when nothing has changed, which is most of the time.

- Delay between an event and the reaction to it
- Load created by checks that mostly find nothing
- Events missed between polling intervals
- Complexity in deciding how often to check

## What a webhook design needs

- **A specific trigger**, rather than notifying on every change
- **Enough payload** for the receiver to act without a follow-up call
- **Failure visibility**, so a broken endpoint is noticed
- **Idempotency**, so a repeated delivery does not act twice
- **Traceability**, so the resulting changes are identifiable

## How to set it up in Jestor

1. Confirm no native automation in **Jestor** already covers the case.
2. Configure the webhook against a specific trigger rather than a general change.
3. Include the record values the receiving system needs.
4. Check the execution log to confirm the trigger fires as expected.
5. Filter the table history by source to trace changes the resulting integration makes.

## Why choose Jestor for event-driven work?

**Jestor** offers webhooks alongside more than 400 native automations, which means webhooks stay reserved for the cases they genuinely suit rather than becoming the default.

The execution log matters most here: silent failures are the characteristic risk of event-driven integration, and a log is what turns a silent failure into a visible one.

## Frequently Asked Questions

### When is a webhook better than polling?

### Should webhooks be my first choice?
