Information about properties

Order of payment methods

To determine the order of display of payment method icons indicate the payment method symbols, separating them with a comma. List of payment methods.

Repeat payment

To use this option the POS should be properly configured in PayU and automatic receipt of payments should be disabled (auto-receipt is on by default). To do that log in to the PayU panel, go to the tab "Electronic payments", then click "My stores" and POS in the given store. The "Automatic payment receipt" option can be found at the bottom under the list of payment methods.

Repeat payment makes it possible to activate multiple payments in PayU to a single order in Magento. The plugin will automatically take receipt of the first successful payment while the other ones will be cancelled. Repeat payment from the buyer's point of view is also possible through the list of orders in Magento (a link "Pay again" will appear there). The buyer will also automatically receive an e-mail with such link. Thus, the buyer is able to successfully pay for his order even if the first payment was unsuccessful (for instance, no funds on the card, problems logging in to the bank, etc.).

Saving cards

Saving card allows logged in users to remember the card for future payments. Each such remembered card is "tokenized", however, Magento does not process the card's full details in any way (they are entered using an embedded widget hosted by PayU) and does not save card tokens in its database (before use, current tokens for the given user are always downloaded from PayU).

To ensure proper functioning of the service additional configuration in PayU, consisting in creating and receiving tokens, is required. Additionally, the principles of authenticating payments with the remembered card can also be determined (by default every payment with a saved card requires providing a CVV code and being authenticated by 3DS but, for instance, an amount limit up to which this will not be necessary can be defined).

The buyer may save the card while making a payment, using the option "Use and save" on PayU widget while entering the card's details. Each card being remembered is subject to strong authentication during first payment (CVV and 3DS). A saved card will appear after choosing to pay with a card through PayU for the order and is visible in the user's account (tab "My saved cards"), where an option to delete it is also available.

Credit widget

To inform customers about credit payment options for a specific product, we recommend placing the credit widget next to products in product lists, in the description (details) of the selected product, in the cart, and at checkout (before payment). The configuration parameters described in the section "PayU Credit widget" plugin parameters allow flexible management of where the credit widget is displayed.
