Send tracking information to PayPal
This step is optional.
Configure your Paypal payments to monitor whenever you fulfill orders on your e-commerce platform and automatically add the tracking code to Paypal! Adding your tracking codes to Paypal is important for a couple of reasons:
It reduces your "Risk-profile" as a seller, meaning you're significantly less likely to have your funds on hold.
Whenever a customer opens a dispute, having the tracking code will help your case.
Adding the tracking code also enables Paypal Seller Protection,
Just click on the Connect with Paypal button and it will start tracking automatically!
