Test-System (Sandbox)
PayU offers a so-called sandbox environment, which enables realistic testing. For this, it is recommended to set up a dedicated Computop MerchantId, which is used for testing only.
PayU test data for this Sandbox-environment can be found here. Please do also consider the PayU error codes: https://devguide.payu.in/split-apis/miscellaneous-3/error-codes/.
