PayPal Checkout

To add PayPal Checkout, you need to configure the settings on the payment gateway side and add the module in BILLmanager. The main difference from the "PayPal" payment method is that this gateway allows for refunds. 

Configuring the payment method

To integrate the payment gateway with BILLmanager add a new application in PayPal PayPal client area → Dashboard→ REST API apps  →  Create App. To set up the integration on the billing system side, you will need the Client_ID and Secret fields. 

Configuring BILLmanager

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

• Step 1 — Select a payment method — choose "PayPal Checkout".
• 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: 

• Application ID — unique identifier. To find the id, log  into your PayPal client area → Dashboard → REST API apps → Client_ID; 
• Secret key — application key to access API PayPal. To find the id, log  into your PayPal client area → Dashboard → REST API apps → Secret ; 
• Test mode — select the check box to activate a test mode for this payment method.  You need to register a new account at  developer.paypal.com ; 
• Logo URL — URL of the provider's logo. Clients will see the logo on the payment page. The recommended size is 190х60 pcs.  We recommend that you start the URL with "https://" so that browsers won't mark the BILLmanager page unsafe.
