# Checkly to Pagerless

> Paste one URL into Checkly. Pagerless decides who to wake, explains it in plain words and closes the problem when Checkly says it's fixed.

## Set up

Your URL is in the Pagerless app under Other tools, with the key filled in:

```text
https://events.pagerless.dev/v1/hooks/checkly/<your ingest key>
```

1. **Open Alert channels, Webhook** In Checkly.
2. **Add a Webhook alert channel with your Pagerless URL.** 
3. **Keep the default template.** 
4. **Optional: set the secret to your ingest key.** 

## What happens

| When | Pagerless |
| --- | --- |
| Fires | Failure; degraded and SSL alerts as warnings |
| Clears | Recovery and degraded recovery |
| How loud | Failure is an alert; degraded and SSL are warnings |
| Proof it's you | Optional `x-checkly-signature`, checked when sent. |

## Choosing who gets woken

| Rule | Example |
| --- | --- |
| Name rules on the URL | `?wake=prod-*&log=*-staging` (globs, case-insensitive) |
| The tool's own severity | critical, p1, sev1, fatal wake; error, warning tell; info, low log |
| A default on the URL | `?level=wake` (or tell, log). Without one: tell. |

`?service=` and `?env=` set the service and environment shown on the problem.
