To accept payments from customers using SEPA Direct Debit, you must first specify your merchant number, which you can obtain from your WorldPay representative. You can specify only one merchant number at the payment gateway level and create multiple collection groups with different merchant numbers based on your requirements. Specify your merchant number(s) as described below:
- Click Configuration > Payments > Payment Gateways > WorldPay.
- Enter your Merchant Number.
- Complete the remaining information based on your requirements.
- Click Save.
Do either of the following:
- Click Configuration > Payments > Collection Groups > New.
- Complete the required fields.
- From the Payment Processor list, select WorldPay.
OR
- Click Configuration > Payments > Collection Groups.
- Click on a collection group for WorldPay.
- Click Processor Details.
- Enter your Merchant Number.
- Click Save.
Your specified merchant number will be used for accounts in the collection group.
Note: Because of a limitation associated with SEPA Direct Debit, Aria does not recommend using authorize and capture in the same API call for payments made using that payment method. Instead, you should first make an authorize API call, confirm that the order has been moved into the authorized status, then attempt to make a capture API call). This will ensure a payment is authorized before the payment is captured and the account balance is reduced. |
