Client Set Up
In order to set up Cart32 to use PayPal for your Cart32 client you need to follow these steps:
  1. You have to have a PayPal account that has signed up and approved to use Website Payments Pro.

  2. Next you need to log on to your PayPal account.

  6. Click View API certificate.




  7. Copy the API UserName, API Password and Signature into the Cart32 administration. All 3 values go on the Cart Settings -> PayPal tab.

  8. There are 2 options to use PayPal Website Payments Pro. One or both can be setup in your cart.

    Option 1: Express Checkout. This is where a customer can check out with directly PayPal. This means that they will go to PayPal's site and get their billing and shipping information and then come back to your Cart32 shopping cart to finish their order. To enable this feature, go to the Cart Settings -> PayPal tab and choose Yes next to the "Use PayPal Express Checkout" radio button choice and click Save.

    Option 2: Merchant Account. This is where a customer can enter in their billing information in Cart32 and have PayPal charge their card without the customer even knowing that it's done through PayPal. To enable this feature, go to the Enterprise Tab. You should be on the "Real Time Card Processing" tab by default. Choose "PayPal Direct Payment" from the list and then check "Use Real Time Card Processing" and click Save.

  9. Make sure that you have the right payment fields turned on. You do this by going to the Cart Settings -> Payment Information tab. Make sure you have "Show" set to "Yes" for the following items: Mastercard, Visa, Discover, American Express, Credit Card, Exp Date and CVV2.


  10. Finally, under the Cart Settings Tab -> Paypal subtab -> PayPal Classic Settings section, enter your PayPal ID in the "PayPal ID/Email" field.
