We're trying to have PayPal Express Checkout payment for a shopping cart (for a live website).
Once the Authorization is completed, we are able to retrieve the Shipping information from the Buyer account (we've successfully tested this on sandbox).
However, is there any 'billing information' that we can get through the API? The owner of the website insists there might be cases where the billing and shipping information are different.
I don't think you can download the billing information for the customer profile. However, you can set up the sales tax to be applied within the 'merchant services' | Shipping and Tax | Tax Calculator. This is where you put in the tax rates to be applied.
