Cron job failed

Get a High-priority push notification when a Render cron job run or one-off job fails, and optionally a quiet one when it succeeds.

How it works

Three steps to your first push

STEP 01

Install the recipe

One click in Studio gives you a personal webhook URL.

STEP 02

Paste your URL into Render

Add it as a webhook for Cron Job Run Ended.

STEP 03

Get a push on your phone

With the text, sound and buttons from the recipe.

Setup

How to set up the Render cron job run ended webhook

Click Install in Studio and sign in. The recipe is added to your account and you get a personal webhook URL.
In the Render Dashboard, open your workspace's Integrations > Webhooks and click + Create Webhook (Pro plan or higher, workspace admins only).
Give it a name and paste your webhook URL as the URL.https://••••••••/•••••••• your personal URL, shown after install
Select the Cron Job Run Ended event and click Create Webhook.
In the Render Dashboard, open **Integrations → Webhooks → + Create Webhook** (Pro plan or higher) with the URL above, and select **Cron Job Run Ended**. Add **Job Run Ended** too if you use one-off jobs.
Only failed runs push by default. Add `?all=1` to the URL to also get a quiet push when a run succeeds or is canceled:
```
your webhook URL?all=1
```
On a **Pro** workspace you get a single webhook URL, so one integration receives every event you select; the recipe ignores the events it doesn't handle. Scale and Enterprise workspaces can add a webhook per recipe.
Render signs deliveries with Standard Webhooks headers (`webhook-signature`), but JustPush doesn't check that signature yet, so keep your endpoint URL private.

The code

What runs when the webhook arrives

Studio calls handleRequest(request) with the incoming webhook and sends the message it returns. It's yours after install; change anything.

transform.js
 1// Render → cron job run ended (and one-off job run ended)
 2// Fires when a Render workspace webhook sends cron_job_run_ended or job_run_ended.
 3// Only failed runs push, unless the webhook URL has ?all=1.
 4// Docs: https://render.com/docs/webhooks

 6// The two event types and how to name what ran.
