# Healthchecks

A product QR code is only as good as the page behind it. Healthchecks watch those destinations and tell you when one stops answering — before a customer standing in a shop finds out first.

![The Healthchecks screen showing healthchecks as inactive, with the button to create one](https://www.unitag.io/documentation/images/packaging/en/packaging-healthchecks.webp)

The screen shows the current state, active or inactive, and Create sets a check up.

## What you configure

- **Interval**: how often the destinations are checked.
- **Retries** and **Retries interval**: how many times a failing destination is tried again, and how long to wait between attempts. This is what keeps a momentary blip from becoming an alert.
- **Healthchecks behavior**: what the check does when a destination fails.
- **Email address**: where the report is sent.

The equivalent for standard QR codes is documented under QR codes, and the reasoning is the same in both places: the failure you want to hear about is the one nobody has noticed yet.
