PayPal payment
1. Create a PayPal app
You need a PayPal business account. Create one if needed, then sign in to the Developer Dashboard and click Create App under Apps & Credentials.
Copy the Client ID and Secret from the app’s basic information.

2. Create the provider in Casdoor
Add a Payment provider, set Type to PayPal, and enter the Client ID and Secret (Client secret).
3. Attach to your product
Add the PayPal provider to your product so users can pay with PayPal.

Notiz
The steps above use PayPal Sandbox. For production, create an app in Live mode and set runmode=prod in Casdoor’s conf/app.conf.
