Therefore ensure to check the “code”-value which indicates success/failure of the action. Only a result of “code=00000000” should be considered successful. |
| URLFailure | ans..256 | M | Complete URL which calls up the 1cs Online Payment System if payment has been unsuccessful. The URL may be called up only via port 443 This URL may not contain parameters: In order to exchange values between the 1cs Online Payment System and shop, please use the parameter UserData. General notes: We recommend using the parameter “response=encrypt” to receive an encrypted response from 1cs Online Payment system However, fraudster may just copy the encrypted DATA-element which are sent to URLFailure and send the DATA to URLSuccess. Therefore ensure to check the “code”-value which indicates success/failure of the action. Only a result of “code=00000000” should be considered successful. |
