Special adjustments

Some payment methods require special adjustments. The next points are only relevant to you if you use the specific payment method:

Creditcard

Field	Description
Credit card Brand	Here you can activate the credit card brands to be used for checkout. You can also define user-defined names for the individual markers.
Minimum Validity of Card	Specifies the number of days a credit card used must still be valid for a transaction. Credits on expired credit cards are not possible.

User-defined display for the hosted iframe

The WooCommerce Extension offers the conformity with the "lowest" Compliance Level according to PCI DSS (SAQ A). Since in this compliance level all credit card data may only be entered in fields hosted by a PCI DSS certified service provider, our extension uses iFrames that are integrated into the checkout. However, these do not inherit the CSS of the shop template, but contain their own style. You can use the following settings to customize these fields.

Field	Description
type	Numeric - Only numbers are allowed and for mobile devices the numeric keyboard is used input type="tel". Password - input type="password" Text - input type="text"
digit count	Length of the field in characters ( HTML attribute size )
max digits	Maximum length of input ( HTML attribute maxlength )
iFrame	Default - Uses width and height from standard style Custom - Uses width and height from the following fields\|
width	CSS - Specify width
Height	CSS - Indication of height
style	Default - Uses CSS specification from "Default Style" Custom - Uses CSS specification from the following field
CSS	Specification of CSS properties for the field Deactivated when Standard is selected beforehand. All CSS properties except "url" are allowed. The following characters are prohibited: "\", "/", "?", "<" and ">"
default style	Text Input - CSS specification for all input fields (HTML input) Select - CSS specification for all selection fields (HTML select )
iFrame	Width - CSS specification Height - CSS specification
Error Output
Error Output Active	Specifies whether card payment errors are to be specified in the checkout.
Error Output Active (Language)	Select the language in which the error message should be returned.

PAYONE Direct debit

Field	Description
Check Bank Data	Specifies whether the IBAN is to be checked before the payment is made.
Use PAYONE Mandate Management	Specifies whether mandate management is to be used by PAYONE. Yes - Within the framework of an order by SEPA direct debit, the customer is shown a mandate text as well as the mandatory data according to the SEPA Rulebook. The end customer must then confirm the mandate by ticking the box. No - The PAYONE mandate management is not used. Without a valid mandate, the customer can revoke the direct debit up to 13 months after payment via the bank!
Download mandates as PDF	If this function is activated, the SEPA Mandate is offered to the end customer for download after the order process (only if PAYONE Mandate Management is active).
List of supported bank countries	Here you can define from which countries SEPA direct debits should be possible.

PAYONE Secure Invoice

This payment method must use a different payment portal together with the corresponding portal key. In addition, the transfer of the shopping basket data is always active here. In order for the payment method to work as desired, it is therefore important that you enter the data from the "secured invoice" payment portal in your PMI in the fields provided for this purpose.

Field	Description
Portal ID	Portal ID of the dedicated payment portal for the PAYONE secured invoice from your PMI
key	The corresponding key

With this payment method, careful selection of the authorization method is particularly important. Since with "Authorization" the demand is written immediately on the PAYONE platform, the platform also immediately sends a corresponding invoice. You should therefore use this authorization method above all if you perform the service immediately.

Editing the orders

Orders placed via the PAYONE Extension for WooCommerce are listed as usual in the order overview of WooCommerce. Order processing differs depending on the authorization method used to process the order.

Capture

Orders placed using the authorization method "Preauthorization" are given the status "On Hold" after the order has been placed.

Only a status change to "Processing" activates the claim on the PAYONE platform and initiates (where possible) the collection of funds. Set the status to "Processing" and click on the blue "Update" button on the right.

The collection is then initiated on the PAYONE platform and acknowledged in the order notes:

Possible errors can also be found in the Order Notes.

Reserved payments are not reserved indefinitely. You should therefore take care to set orders to "Processing" in good time after a preauthorization and thus collect the payment or write the claim. Here are some (non-binding) guide values for the validity of the reservation:

Credit card - 7 days (sometimes longer, varies from bank to bank)

PayPal - 29 days

PAYONE Secure Purchase on Account - 28 Days

Refund

Credit notes use the familiar WooCommerce credit note process. A click on the button "Refund" in the order opens the menu for credit notes:

Here you can enter the amount credited and a reason. Important: "Refund manually" does not credit the money on the payment method, but only in WooCommerce. Use this option only if you do not want to transfer money back or if you use other ways than the PAYONE platform.

Due to limitations in the way that WooCommerce manages orders, the shop's standard tax rate for the entire credit amount is always transferred for credit notes with shopping basket transfer. This is especially important when the PAYONE platform takes care of document dispatch for you. This is the case, for example, with the PAYONE Safe Invoice payment method.

However, if you wish to credit a shopping cart that contains items with different tax rates or mixed tax rates, please use the credit function in the PAYONE Merchant Interface. There you have the option of creating individual shopping basket items together with the tax rate, which are then displayed correctly on the document.

Extended configurations

Here you will find separate setting options that allow you to customize our plugin more precisely to your needs.
