Order paid
Get a push notification with the amount, product and customer every time a Polar order is paid, including new subscriptions and renewals.
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 Polar
Add it as a webhook for order.paid.
STEP 03
Get a push on your phone
With the text, sound and buttons from the recipe.
How to set up the Polar order.paid webhook
- Click Install in Studio and sign in. The recipe is added to your account and you get a personal webhook URL.
- In the Polar dashboard, open Settings > Webhooks and click Add Endpoint.
- Paste your webhook URL as the URL and leave the format on Raw.https://••••••••/•••••••• your personal URL, shown after install
- Generate a secret (JustPush doesn't need it), tick the order.paid event and save.
- Tick **order.paid**, not `order.created`: renewal orders are created as *pending* before the payment goes through, while `order.paid` only fires once the money is in. It covers one-time purchases, new subscriptions and renewals, each with its own title.
- Don't want a push for every renewal? Add `?renewals=0` to the URL. Testing in the **sandbox**? Add `?sandbox=1` so the button opens the sandbox dashboard:
- ```
- your webhook URL?renewals=0
- ```
- Polar signs every delivery (`webhook-id`, `webhook-timestamp`, `webhook-signature`; Standard Webhooks for secrets made on or after 8 September 2026), but JustPush doesn't check that signature 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.
