Well, guys, I have some doubts. The Transparent PagSeguro Checkout API implementation is working correctly in PHP, but purchases are being canceled. This is most likely due to invalid buyer data (credit card), but I have not found it yet. Some tests I did, the data was wrong, and with that I believe the card has been blocked, so it cancels all others. I would like to know if you know the necessary data, other than the cards themselves: The address and date of birth must match those of the card ??? Because I missed these ... Or have they blocked the IP of my server for several attempts at low values ???
The pagseguro does not give me a response and there is no log indicating the reason for the cancellation.
