what is the difference between firstdata , payeezy, FirstData_Connect, FirstData_Webservice,FirstData_Payeezy

i was searching for first data gateway api and i am stuck with the lots of names.

what is the difference between.

firstdata payeezy FirstData_Connect FirstData_Webservice FirstData_Payeezy

are those all separate gateways. if yes. then do i have to integrate different api for all of them. can anyone give me the api docs. link for all of them.

thanks.

Solution

First Data Connect and First Data Webservice API are integration methods for an older payment gateway that First Data is slowly phasing out. They've already phased out Connect. Payeezy is First Data's e-commerce gateway going forward.
