This site looks like it hasn't been updated in 10 years. It's hard to use, and they put the wrong category for my business on the customer statements. They said it's coming from Chase/Paymentech, but I called Chase, and they told me it's coming from Authorize.net because it is correct in their system.
If you want to pass the name on the card, you have to use two fields for first and last names. You cannot use one full name field like Amazon does, for example. Internally we use only one field because we sell to different countries and one field is much easier for our customers who are not in the U.S.
Their customer service is terrible as well. I was trying to enable the PayPal option, but it gave me an error. I opened a case, and they just closed it after two weeks and said they have no estimate when it will be fixed. They also said they escalated it to an engineer and asked me for my login names, but 6 months later it is still not fixed! I even posted it on their community board, but received no reply from anyone. I did not really wait for them and integrated PayPal directly without Authorize.net, and it works fine.
Also their SDK is old. It does not work with. NET Core. They uploaded a beta release 4 years ago, which no longer works, and they never bothered to update it. They literally said they will support it and then never updated it or even replied to any one asking if update is coming.
I am considering moving to Stripe or another service that's more up-to-date and easier to use.
