Hot to simulate all the error codes

To simulate all the error codes, merchant should submit "customParameters[forceResultCode] = Desired result code” in the request. E.g. customParameters[forceResultCode] =800.100.100 

Sample checkout request:
//
authentication.userId= Your account userID
authentication.password= Your account password
authentication.entityId= Your account entityId
amount=92.00
currency=EUR
paymentType=PA
customParameters[forceResultCode]=800.100.100 [Pass any code that you want to simulate]
//
Merchant can use the customParameters[forceResultCode] request attribute for both Server2Server and SecurePay integration API calls.

Test cards to simulate different 3D secure results [ECI] can be found here .
