Validating data in Dev Studio
GoGoRoad customers with Standard coverage provide credit card information during the Submission stage of an Assistance Request case to pay for services performed by the company. To reduce the chance of an error when processing the credit card information, stakeholders want to validate the credit card information provided by customers.
A senior developer created an edit validate rule named IsDigit to verify that a credit card number contains only numbers. Configure a validate rule for the Enter Payment Information step to validate entries in the Card number field by applying the IsDigit edit validate rule and entries in the Expiration date field by applying the EnterPaymentInformation validate rule.
The following table provides the credentials you need to complete the challenge.
