This action is used to designate fields as required on the Payment Pages when the associated condition(s) has been met.
e.g. For Mastercard transactions, you could specify the billing name as required.
If the customer fails to enter the information required when performing a payment, the relevant fields are highlighted in red and the customer is shown an error message to convey the problem. This allows the customer to make corrections and re-attempt the payment.
All required fields are highlighted with an asterisk.
When creating the action, you will need to specify the fields required when the condition has been met.
