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 Linear

Add it as a webhook for Issues.

STEP 03

Get a push on your phone

With the text, sound and buttons from the recipe.

Setup

How to set up the Linear issues 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 Linear, go to Settings > API and click New webhook (workspace admins only).
  3. Paste your webhook URL as the URL and pick the team (or all public teams).https://••••••••/•••••••• your personal URL, shown after install
  4. Tick the Issues resource type and save.
  5. Create a webhook under **Settings → API → New webhook**, pick the team, and tick **Issues**. To only hear about issues assigned to **you**, add your email (or name) to the URL:
  6. ```
  7. your webhook [email protected]
  8. ```
  9. Linear signs deliveries with `Linear-Signature` (HMAC-SHA256), 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// Linear → issue assigned
2// Fires when an issue's assignee changes. Add [email protected] to the URL to only
3// hear about issues assigned to you.
4// Docs: https://linear.app/developers/webhooks
5
6// Linear priority (0 none, 1 urgent … 4 low) → push priority.
7const PRIORITIES = { 1: 1, 2: 0, 3: 0, 4: -1, 0: 0 }
8
9// Only link to real http(s) URLs.
10function link(url, cta) {
11 return typeof url === "string" && /^https?:\/\//.test(url) ? [{ cta, url }] : []
12}
13
14function handleRequest(request) {
15 const body = request.body || {}
16 const data = body.data ?? {}
17
18 // Guard: only issue updates where the assignee changed to someone.
19 if (body.type !== "Issue" || body.action !== "update" || !("assigneeId" in (body.updatedFrom ?? {})) || !data.assignee) {
20 console.log("Not an issue assignment — skipping")
21 return null
22 }
23
24 // [email protected] (or a name) limits pushes to one person's assignments.
25 const only = typeof request.query?.assignee === "string" ? request.query.assignee.trim().toLowerCase() : ""
26 const matches = [data.assignee.email, data.assignee.name].some((value) => typeof value === "string" && value.toLowerCase() === only)
27
28 if (only && !matches) {
29 console.log("Assigned to someone else — skipping")
30 return null
31 }
32
33 const details = [data.team?.key, data.priority ? data.priorityLabel : null, data.state?.name, body.actor?.name ? `by ${body.actor.name}` : null]
34
35 return {
36 title: `👤 ${data.identifier ? `${data.identifier} ` : ""}assigned to ${data.assignee.name ?? "someone"}`,
37 message: [data.title, ...details].filter(Boolean).join(" · "),
38 topic: "Linear",
39 priority: Object.prototype.hasOwnProperty.call(PRIORITIES, data.priority) ? PRIORITIES[data.priority] : 0,
40 buttons: link(data.url ?? body.url, "Open issue"),
