Alert
Get a push notification when Opik sees trace errors or guardrail hits, or when cost, latency or feedback scores cross a threshold.
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 Opik
Add it as a webhook for Trace alert.
STEP 03
Get a push on your phone
With the text, sound and buttons from the recipe.
How to set up the Opik trace alert webhook
- Click Install in Studio and sign in. The recipe is added to your account and you get a personal webhook URL.
- In Opik, open Production > Alerts and create an alert with destination type General.
- Paste your webhook URL as the webhook URL and select the Trace alert events.https://••••••••/•••••••• your personal URL, shown after install
- Use Test trigger to send the example payload, then save.
- In Opik, open **Production → Alerts**, create an alert with destination type **General**, paste the URL above, and select the events you want: `trace:errors`, `trace:guardrails_triggered`, `trace:cost`, `trace:latency`, `trace:feedback_score` or `trace_thread:feedback_score`.
- **Test trigger** sends Opik's example payload. Opik groups events that happen close together, so one push can cover several traces.
- Opik can send a secret token as `Authorization: Bearer …`, 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.

The Opik trace:errors webhook
This is what Opik sends to your URL for trace alert. It is a sample, trimmed to the fields recipes use.
