PayPal integration FAQ
Do I need to create my own auth app to connect PayPal to StackOne?
Yes, you need an auth app inside the PayPal Developer Dashboard. PayPal calls this a "REST API app" (Merchant type). Once created, paste the Client ID and Secret into the StackOne dashboard auth config for the PayPal connector, with Sandbox or Live environment selected. See the PayPal auth docs.
