PayPal

To add PayPal, you need to configure the settings on the payment gateway side and add the module in BILLmanager.

Configuring the payment method

To accept payments via PayPal BILLmanager uses the Website Payments Standard mechanism and checks payments via IPN notifications. Log in to PayPal to activate IPN notifications: Profile → Profile and settings → My selling tools → Getting paid and managing my risk → Instant payment notifications — Update. Enter the URL: 'https://<BILLmanager_URL>/mancgi/ppresult'. 

When a client makes a payment PayPal addresses BILLmanager to pass the transaction completion information. You can find all the notifications that were sent to the billing system on the "IPN history" page (the name may vary depending on a selected language). 

You can set up additional payment parameters in the following sections:

• Profile → Profile and settings → My selling tools → Getting paid and managing my risk → Block payments — Update. 
• Profile → Profile and settings → My selling tools → Selling online → Website preferences — Update. 

Configuring BILLmanager

Navigate to Provider → Payment method and complete the following fields:

• Step 1 — Select a payment method — choose "PayBox".
• Step 2 — Integration settings. Enter the integration details. 
• Step 3 — Payment method settings. Enter the payment method parameters. 

Integration

Client — select the existing account or register a new one. If you choose "Use existing", enter the following details:

Additional information

Refund 

Refund is not supported.  

Logging

PayPal has the following log files:

• '/usr/local/mgr5/var/pmpaypal.log' — configuration details of the payment method.
• '/usr/local/mgr5/var/pppayment.log' —  payment log.
• '/usr/local/mgr5/var/ppresult.log' — payment check  upon receiving an IPN message 

Possible issues

When crediting payments you may face the issue if the notifications passed by PayPal (in the IPN history) differ from the notifications in the 'ppresult.log' log file. To resolve the issue, configure IPN notification encoding in PayPal: Profile → Profile and settings → My selling tools → More selling tools → PayPal button language encoding.
