Paddle

Paddle handles payments, tax, and subscriptions for digital products.

1. Get API key

Sign in at Paddle. In Developer Tools → Authentication, create an API key with permission to create transactions. Copy the key.

2. Create the provider in Casdoor

Providers → Add. Set Category to Payment, Type to Paddle. Put the API key in Client secret. Client ID is not used for Paddle.

3. Attach to a product

Add the Paddle provider to the product in Casdoor. Checkout redirects users to Paddle. Paddle creates transactions dynamically; you do not need to pre-create products in Paddle.

Sandbox vs production is determined by Casdoor’s runmode in conf/app.conf.
