Chargeback received
Get a High-priority push notification when a Paddle payment is charged back, or when an early fraud warning suggests one is coming.
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 Paddle
Add it as a webhook for adjustment.created.
STEP 03
Get a push on your phone
With the text, sound and buttons from the recipe.
How to set up the Paddle adjustment.created webhook
- Click Install in Studio and sign in. The recipe is added to your account and you get a personal webhook URL.
- In Paddle, go to Developer tools > Notifications and click New destination.
- Choose Webhook as the type and paste your webhook URL as the URL.https://••••••••/•••••••• your personal URL, shown after install
- Select the adjustment.created event and save the destination.
- Refunds, credits and chargebacks all arrive as `adjustment.created`. This recipe only reacts to chargebacks and chargeback warnings, so you can point the refund recipe at the same event without double pushes.
- The **View transaction** button opens the live Paddle dashboard. Paddle doesn't say in the event whether it came from sandbox or live, so if you're testing in sandbox, change `DASHBOARD` at the top of the code to `https://sandbox-vendors.paddle.com`.
- Paddle signs each webhook with a `Paddle-Signature` header, but JustPush doesn't verify it yet. 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.
