Settings from other Paddle plugins are not imported, but switching takes only a few minutes.
- Enter your Paddle credentials in Downloads → Settings → Payments → Paddle and run Test connection.
- Point Paddle at the new webhook address,
https://your-store.com/wp-json/wpinterface-paddle/v1/webhook. For Billing use Set up webhook; for Classic paste it as the Alerts URL. - Deactivate the other plugin once Paddle is set up here, so only one gateway answers Paddle’s webhooks.
