Configure advanced settings

We have designed our PrestaShop plugin to guarantee you a quick and easy way for transaction processing. The following settings are optional, but you might use them to optimise your customers’ payment experience and to adapt to business requirements.

To do so, follow these steps:

1. Login to the PrestaShop Back Office. Go to IMPROVE > Modules > Module Manager > Payment. Click on "Configure" next to "Worldline Online Payments".
2. Make sure "Show advanced settings" is set on YES. Go the "ADVANCED SETTINGS" tab and configure the following settings:
   
   

   Property	Description/Actions
   Transaction Type	Define whether to process the transactions as authorisation mode or as direct sale. Select one of the following options: Immediate (Authorization + Capture): The amount has been ordered to be paid out in one go. Use this mode to receive the money before shipping the order There are no further actions required to capture the transaction. Successful transactions will have status="CAPTURED" / statusOutput.statusCategory="COMPLETED" / statusOutput.statusCode=9 Authorized (Authorization Only): the amount is only blocked on your customer's card. Successful transactions will have status="PENDING_CAPTURE" / statusOutput.statusCategory="PENDING_MERCHANT" / statusOutput.statusCode=5 (Use this mode when you wish to capture a transaction only after shipping the order) If you select "Authorized", also configure the following: Delay before payment capture: You can set the capture delay of X days in the given field. At the end of this duration, a cron job will capture the transaction automatically. If the transaction is partially captured already in the meantime, any available funds that remain will be captured. Capture cronjob: Copy the cron command from the plugin and paste it in your PrestaShop core for it to auto execute. If transaction type is set to Authorized , beware of the following: Make sure that you capture authorised transaction later. Only then will the transaction have status="CAPTURED" / statusOutput.statusCategory="COMPLETED" / statusOutput.statusCode=9, for which you receive the actual payment for the transaction. Even if the capture delay is set to X days, you can also manually capture funds fully / partially by opening an individual order once you have delivered the goods/services.
   Enable Advanced Logging	If you are in debug mode and need additional logs for troubleshooting, enable this setting. Download any available logs right here.
   Payment Flow Modification	We strongly recommend leave the settings as-is to guarantee safe transaction processing: Payment accepted status mapping: Map successful transaction statuses according your business logic. Pending payment status mapping: Map pending transaction statuses according your business logic. Payment error status mapping: Map unsuccessful transaction statuses according your business logic. Release inventory from Pending payment orders after: For any orders in an unknown status, select the time frame after which an automatic cron job will delete the order in the PrestaShop and on our platform. Pending Order Cronjob: Copy the cron command from the plugin and paste it in your PrestaShop core for it to auto execute. Force 3DsV2: (De)activate the 3-D Secure check. We strongly recommend setting it to YES to avoid a high rate of declined transactions. This mapping relates only to PrestaShop transaction statuses. The PAYONE E-Payment statuses are unaffected by this setting.
