Healthchecks.io cron alerts on your phone

A push when a cron job fails to check in, and another when it does again, from Healthchecks.io's webhook integration with the check's name in the title.

Healthchecks.io's own page was read on 12 September 2026 for every step below. If a menu has moved since, write to hello@youlmk.com and it is corrected the same day.

What Healthchecks.io sends

An HTTP request you shape with its placeholders ($NAME, $NAME_JSON, $STATUS, $NOW, $TAGS, $CODE, $JSON) when a check goes down, and another when it goes up; two retries on failure.

What arrives in the inbox

Set it up

In YouLMK, create a source of type webhook named after the service, and copy its webhook URL: youlmk.com/w/k_7hq2nk3f9qd8w4 with your own key. Then:

1. In Healthchecks.io, open Integrations, then Webhook, and name the integration.
2. Under "Execute when a check goes down": method POST, your source's webhook URL from YouLMK as the URL, the Request Body {"title": $NAME_JSON, "body": "went $STATUS", "priority": "high"}, and a Request Header line Content-Type: application/json.
3. Under "Execute when a check goes up": the same URL and header, with the body {"title": $NAME_JSON, "body": "is up again"}.
4. Save the integration and assign it to the checks it should cover.

Make it quiet where it should be

Everything above lands with the source's own rules: its Reach (Silent, Badge, Banner, Break through), whether quiet hours hold it, and grouping of repeats into one card. Set them once on the source, in the app or at app.youlmk.com; the service never has to change. Unknown fields arrive as rows on the card, up to six; the whole request is capped at 8 KB (Webhooks).

Try it

The trial is 10 notifications and 3 watches, no card. Get your key, or read the webhooks reference first.
