How it works

Three steps to your first push

Install the recipe

STEP 02

Paste your URL into Opik

Add it as a webhook for Experiment finished.

STEP 03

Get a push on your phone

With the text, sound and buttons from the recipe.

Setup

How to set up the Opik experiment finished webhook

  1. Click Install in Studio and sign in. The recipe is added to your account and you get a personal webhook URL.
  2. In Opik, open Production > Alerts and create an alert with destination type General.
  3. Paste your webhook URL as the webhook URL and select the Experiment finished events.https://••••••••/•••••••• your personal URL, shown after install
  4. Use Test trigger to send the example payload, then save.
  5. In Opik, open **Production → Alerts**, create an alert with destination type **General**, paste the URL above, and select the `experiment:finished` event. Experiment events are workspace-wide.
  6. Opik can send a secret token as `Authorization: Bearer …`, but JustPush doesn't check it 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// Opik → experiment finished
2// Fires when an Opik experiment completes, if an alert with a General webhook destination
3// subscribes to "experiment:finished". Shows the experiment's feedback scores.
4// Docs: https://www.comet.com/docs/opik/production/alerts

6function handleRequest(request) {
7 const body = request.body || {}

9 // Guard: only experiment:finished events.
10 if (body.eventType !== "experiment:finished") {
11 console.log(`Ignoring Opik "${body.eventType ?? "unknown"}" webhook`)
12 return null
13 }

15 const meta = body.payload?.metadata
16 const experiments = Array.isArray(meta) ? meta : meta ? [meta] : []

19 ? first.feedback_scores
20 .filter((score) => score?.name && Number.isFinite(Number(score.value)))
21 .slice(0, 4)
22 .map((score) => `${score.name} ${Math.round(Number(score.value) * 100) / 100}`)
23 : []
24 const more = experiments.length > 1 ? ` (+${experiments.length - 1} more)` : ""
25
26 return {
27 title: `🧪 Experiment finished${first.name ? `: ${first.name}` : ""}`,
28 message: (scores.join(" · ") || "No feedback scores yet") + more,
