I have signed up for Intuit (GoPayment) Merchant Services Webstore. I thought it would be better than most plugins so I can take any kind of credit card. They've given me a "connection ticket" to connect the service to my actual website. It's just a combination of letters, numbers, and dashes. They've just stated to insert this into the software of my website but I have no idea how to do that since it's not in html.
Can somebody help me out here?
