Connecting Worldpay

Connecting Worldpay and Splitit requires that you first adjust settings in your Worldpay admin, then add your Worldpay credentials to Splitit.

Settings in Your Worldpay Merchant Admin

Log into your Worldpay Merchant Administration Interface account and navigate to the installation menu.

Configure MID

1. In your Worldpay account, access your dedicated Merchant ID (MID) for Splitit transactions.

2. Under Integration > Configuration Details set Capture Delay to Off.

Request Settings from Worldpay Support

Contact your Worldpay account manager or customer support and request that they enable the following in your Worldpay account:

  • Multiple Partial Captures: Have your Merchant ID (MID) set to accept "Multiple Partial Captures." (This will enable several smaller captures for one total authorization.) Note that "Multiple Partial Captures" is set separately for Visa/Mastercard (first, default group) and American Express/Discover (second group), so if you accept either or both cards in the second group (American Express/Discover), you will need to explicitly request that it be enabled in addition to Visa/Mastercard.
  • Tokenization: Have tokenization enabled. This payment processing is done using a token, instead of sharing PAN details over the network.

Make sure that you receive email confirmation of your changes.

Set Webhooks

Under Integration > Merchant Channel > Merchant Channels (Production), add the webhook sending address "" next to http. Alternatively, if you are just testing, add the address "" under Merchant Channels (Test). For either environment, select the webhooks for CAPTURED, REFUNDED, REFUND_FAILED, SENT_FOR_REFUND, REFUNDED_BY_MERCHANT, and CHARGED_BACK in the http row under Merchant Channel Events, then click Save Settings.
