Thanks for the new feature support. Can you add test for it? The test needs to cover both of True and False cases.

To make the change clear: the response format was not changed, right?

[brandon-clair]

@youknowone A test has been added! Since the parameter is optional, and defaults to False, the current suite of tests cover that case. I have added a case where the parameter is submitted as True.

Correct, the response format has not been altered. This is to support a new, optional parameter for verification requests, exclude-old-transactions.
