If you want to contact Worldline, it is always important to perform 3 tests; CTMP, Parameterization, and Keyloading (this checks if the terminal is connecting externally and connecting to the Acquirer)

Record the result for each test.
After the tests, always try to perform an EMV reset. Then have the customer perform a test transaction.
If the test transaction fails, call Worldline.
