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 Clerk

Add it as a webhook for user.deleted.

STEP 03

Get a push on your phone

With the text, sound and buttons from the recipe.

Setup

How to set up the Clerk user.deleted 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 the Clerk Dashboard, open Webhooks and click Add Endpoint.
  3. Paste your webhook URL as the Endpoint URL and subscribe to user.deleted.https://••••••••/•••••••• your personal URL, shown after install
  4. Click Create. The endpoint's Testing tab can send an example event.
  5. In the Clerk Dashboard, open **Webhooks → Add Endpoint** and subscribe to **user.deleted**. Webhooks are set up per instance, so add the endpoint to your production instance.
  6. Clerk's `user.deleted` payload only contains the user's ID (and `external_id` when you set one), not their name or email. To look them up, search the ID in your own database.
  7. Use the endpoint's **Testing** tab and **Send Example** to try it.
  8. Clerk sends webhooks through Svix and signs every delivery (`svix-id`, `svix-timestamp`, `svix-signature`), but JustPush doesn't check that signature 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// Clerk → user.deleted
2// Fires when a user deletes their account, or is removed in the Clerk Dashboard or API.
3// Clerk only sends the user's ID (and external ID, if set), not their name or email.
4// Docs: https://clerk.com/docs/guides/development/webhooks/syncing
5
6// A trimmed string (or number), or null.
7function text(value) {
8 if (typeof value === "number" && Number.isFinite(value)) return String(value)
9 return typeof value === "string" && value.trim() ? value.trim() : null
10}
11
12function handleRequest(request) {
13 const body = request.body && typeof request.body === "object" ? request.body : {}
14 const data = body.data && typeof body.data === "object" ? body.data : null
15
16 // Guard: only user.deleted, so other Clerk events on this integration stay quiet.
17 if (body.type !== "user.deleted" || !data) {
18 console.log(`Ignoring Clerk "${body.type ?? "unknown"}" event`)
19 return null
20 }
21
22 const id = text(data.id)
23 const external = text(data.external_id)
24
25 return {
26 title: "🗑️ User deleted",
27 message: `${id ?? "A user"} was deleted${external ? ` (external ID ${external})` : ""}`,
28 topic: "Clerk",
29 priority: 0, // Normal: losing a user is worth knowing
30 }
