Well, there are two ways to trigger that sort of error. The verbose descriptions are as follows:
- A transaction with identical amount and credit card information was submitted within the previous two minutes.
- This is a processor-issued decline.
I'm guessing you're getting the former rather than the latter. Now, what you want to do about it, I don't know. Can you describe what you're trying to do with "x_duplicate_windows"? I do not believe I have heard of that field, and I can't find it in the documentation.
