Paypal Business Account

To use this payment processor, you will need a PayPal Business account set up and working.

  • The PayPal payment processor communicates with your PayPal account during checkout.
  • When your shopper selects PayPal as their payment option,  they will be taken to the PayPal website to complete the payment.
  • Your website and PayPal account will update one another.

To set up the PayPal payment processor, go to Shopping Cart >> Store >> List Payment Methods


If there is already a payment processor named PayPal (new), open it (click the name), and enter your account information. If there is no payment module with the name PayPal (new) you will need to create it.

The “General” tab allows you to modify the active state, payment method name which we recommend you to remove the (new), the payment method code (displayed on the order), the shopper group association, discount and the processor’s list order.

The “Configuration” tab is for your business PayPal account information. It requires your PayPal API username, password and signature which is provided by PayPal and can be found on your business PayPal account.

3. Name the method “PayPal”, give it code “NPP” and class name “ps_new_paypal” & select the type “PayPal (or related)”

4. Click on the Save button on the top right

5. Now open the new PayPal payment method you just created to add in the credentials.

6. For the next step click on the Configuration tab and populate the API Signature Credentials you copied from PayPal.
