Build finished
Get a High-priority push notification when a Buildkite build fails, and optionally a quiet one when it passes, is canceled or waits on a block step.
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 Buildkite
Add it as a webhook for build.finished.
STEP 03
Get a push on your phone
With the text, sound and buttons from the recipe.
How to set up the Buildkite build.finished webhook
- Click Install in Studio and sign in. The recipe is added to your account and you get a personal webhook URL.
- In Buildkite, go to Settings > Notification Services and click Add on Webhook.
- Enter a description and paste your webhook URL as the Webhook URL.https://••••••••/•••••••• your personal URL, shown after install
- Tick the build.finished event, choose which pipelines (and branches) to watch, and click Add Webhook Notification.
- In **Settings → Notification Services**, add a **Webhook** with the URL above and tick **build.finished**. Pick the pipelines to watch, and optionally a branch filter such as `main` so only builds on that branch push.
- Only failed builds push by default (High priority). Add `?all=1` to the URL to also get quiet pushes when a build passes or is canceled, and a Normal one when it stops at a block step waiting for approval:
- ```
- your webhook URL?all=1
- ```
- Want to know sooner? The **Build failing** recipe fires as soon as the first job fails, while the build is still running. If you tick both events on one webhook, a failed build pushes twice: once while failing and once when it finishes.
- Saving the webhook sends a ping, which gives a quiet **🔔 Buildkite connected** push.
- Buildkite sends your webhook token as `X-Buildkite-Token` (or an HMAC-SHA256 `X-Buildkite-Signature`), but JustPush doesn't check it yet, so keep your endpoint URL private.
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.
