Error when sending request

[gennaropesantes]

I keep getting this error when i input credit card information 

Fatal error: Class 'SquareConnect\Api\TransactionApi' not found in /data/24/3/145/74/3308400/user/3692243/htdocs/wp-content/themes/iconic-one/process-card.php on line 29

I made sure the name is correct and the path is correct but I can't wrap my head around this.

P.S. I am using wordpress and simple trying to skip the whole cart/shopping part to just be able to send money (like a donation) is this possible?

Did you make the process-card.php file, or are you using a theme made from someone else? This error is probably caused by you not including the Square API PHP Library in that file.
