Paddle

Connect

  1. In Paddle, create an API key under Developer tools → Authentication, with the notification_setting.write permission.
  2. Paste it (pdl_live_apikey_…) into Setup → Payments → Paddle.

DataPenny creates the webhook and never stores the key.

By hand

Add a destination under Developer tools → Notifications, with the type set to Webhook and Platform events, pointing at https://YOUR-DATAPENNY-URL/api/webhooks/paddle/YOUR_SITE_ID. Subscribe to transaction.completed, adjustment.created and adjustment.updated, then paste the secret key (pdl_ntfset_…) under Connect by hand.

Checkouts

Paddle checkout links can’t carry custom data, so pass it to Paddle.js:

Paddle.Checkout.open({
  items,
  customData: {
    datapenny_visitor_id: datapenny.visitorId(),
    datapenny_session_id: datapenny.sessionId(),
  },
});

Or put the same JSON in a data-custom-data attribute on your paddle_button. Paddle copies it to the subscription, so renewals are credited too.

Past sales

Paddle history can’t be imported yet. New sales arrive from the moment the webhook is connected.
