Order refunded
Get a low-priority push notification when a Polar order is fully or partially refunded.
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.refunded.
STEP 03
Get a push on your phone
With the text, sound and buttons from the recipe.
How to set up the Polar order.refunded 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.refunded event and save.
- Tick **order.refunded**. It fires for full and partial refunds and carries the whole order, so the push can name the customer and product. (`refund.created` fires for every refund whatever its status, and without the customer's name, so this recipe doesn't use it.)
- The amount is the total refunded on the order so far, including tax. A second partial refund on the same order shows the new running total.
- Testing in the **sandbox**? Add `?sandbox=1` to the URL so the button opens the sandbox dashboard.
- 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.
