Set up Worldpay account#

Before configuring the Worldpay extension, you need to do some configuration in the Worldpay merchant portal. Your organization should have a corporate account with Worldpay. Use those account credentials here: Worldpay login.

After logging in, you need to select a merchant code and application if your organization has more than one. For further information about the Merchant Admin Interface, please visit the Worldpay support documentation.

    Worldpay target settings
    • BATCH_XML_VERSION: change the default version only if you have a specific reason for doing so
    • CURRENCY: Enter your default currency. If your org has multi-currency support enabled, this setting is ignored, and the currency from the installment is used instead.
    • MERCHANT_CODE: your code from the Merchant Admin Interface
    • RECORDS_PER_FILE: unless otherwise decided, leave this at the default value. If the number of transactions exceeds this threshold, FinDock creates multiple files for bulk collection
    • Upload Copy to Chatter: enable if you want the generated bulk payment file that is sent to Worldpay to also be uploaded to Chatter
    • XML_API_ENDPOINT: use the same endpoint here as in the Worldpay extension settings
    • XML_API_USERNAME: use the same username here as in the Worldpay extension settings
    • XML_API_PASSWORD: use the same password here as in the Worldpay extension settings
  8. When you are done filling in the settings, click Save.

Refund handling#

Worldpay for FinDock supports both partial and full refunds. The refund handling differs based on the refund type:

  • Full refund: the status of the installment is set to ‘Reversed’ and a negative payment with the full rund amount is created.
  • Partial refund: the status of installment is to ‘Partially paid’ and a negative payment with the amount of the partial refund is created.

Payment API#

To test your Worldpay configuration for one-time payments, you can use the following API messages.

If your configuration is correct, you should be able to navigate to the RedirectURL provided in the response and pay the amount specified. When a redirect ends in an unexpected error, the error message is stored in the last status reason of the installment.

note

In production, recurring credit card tokens are created with an initial lifetime of four years. In testing , tokens are created with a lifetime of seven days.

This following request initiates a one-time credit card transaction with Worldpay.

    {      "FailureURL": "https://www.example.com/error",      "Origin": "API Test",      "Payer": {        "AllowDeduplication": true,        "Contact": {          "Email": "test@demo.com",          "FirstName": "Test",          "LastName": "Tester"        },        "ContactUpdate": "replace"      },      "Payment": {        "Amount": "25"      },      "PaymentMethod": {        "Name": "Creditcard",        "Processor": "PaymentHub-WorldPay"      },      "SourceConnector": {        "Name": "PaymentHub"      },      "SuccessURL": "https://www.example.com/success"    }
