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 Issue SLA.

STEP 03

Get a push on your phone

With the text, sound and buttons from the recipe.

Setup

How to set up the Linear issue sla 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 Issue SLA resource type and save.
  5. Create a webhook under **Settings → API → New webhook** with the URL above and tick **Issue SLA**. SLAs must be enabled for the team.
  6. The sample is modelled on Linear's schema; the SLA event's exact type name isn't documented, so the recipe checks the `highRisk`/`breached` action and the issue data instead.
  7. 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 SLA at risk or breached
2// Fires when an issue with an SLA is at high risk of breaching, or has breached it.

28 priority: breached ? 2 : 1, // A breached SLA is a promise to a customer already broken
29 buttons: link(issue.url ?? body.url, "Open issue"),
