I have been on the phone with First Data and they gave me the exact instructions for the plugin with a download file from their website, i have entered all data as far as I can tell according to their directions. The KEY password, I entered just as it is on the .txt file, and the shop ID and API password I entered from the WSXXXXXShopNumber._.1.auth.txt file that has a user id and password in it. I did not select a zone. I uploaded the .key and .pem files to the safe folder and put the absolute path. I cannot figure out what is wrong, can I PM you the login to look at it for me, thanks, Carin
