How To: Set up PayPal Express Checkout in CS-Cart¶

1. In the Administration panel, go to Administration → Payment methods.
2. Сlick the + button (Add payment method) in the top right corner of the page.
3. Fill in the form:
   • Select PayPal Express Checkout in the Processor drop-down list.
   • Enter the Display name—the name of the payment method that will appear to your customers at checkout. By default, the payment method will be called PayPal Express Checkout.
   • Specify other settings and upload an icon for the payment method, if necessary.

4. Switch to the Configure tab and specify the settings of PayPal Express Checkout:

   • Currency—the currency of your PayPal account.

     This currency must exist in your store and, ideally, it should be your primary currency. That is because prices are always converted to PayPal currency according to the rates you specified, before being sent to PayPal.

   • Order prefix (optional)—any prefix you want invoice IDs to have on PayPal site (for example, mycart). Using the prefix allows to prevent duplicate invoice IDs when you use the same PayPal account to accept payments from several websites.

   • Use In-Context Checkout—tick this checkbox if you want to use In-Context Checkout. Please note that In-Context Checkout won’t be used when the store is running in the Widget mode.

5. Make sure to fill in the Technical details:

   • Merchant ID—this field is required if you choose to use In-Context Checkout. You can find Merchant ID in your PayPal account.

   • Username—your PayPal Express Checkout API username.

   • Password—your PayPal Express Checkout API password.

   • PayPal authentication method—select the desired authentication method:

     • If you select Certficate: upload a certificate file in the Certificate filename section. Make sure that there are readable permissions for the certificate file and for the directory where it is located on your server.
     • If you select Signature: enter your signature in the corresponding field.

     Note

     You can get the certificate and signature, as well as other API access credentials, from your account on www.paypal.com.

   • Send customer shipping address—tick this checkbox if you want to send the customer’s shipping address to PayPal.

   • Test/Live mode—select Live mode.

     You can use the Test mode to see how the payment method works. But this mode doesn’t work with live PayPal accounts. For testing you’ll need to use test accounts from PayPal Sandbox.

6. Click the Create button.
