Can I create Service-Backed_Record with POST API which returns data on input parameter, How differently it works from GET API. What could be the possible I may face if I use POST API for Service-Backed_Record.

There is no difference. The only thing is that when selecting POST as method, Appian assumes that you want to modify data in the other system. So you have to switch "Usage" back to "Queries Data".
So I can use the external system POST API as a source for my Service-Backed_Record without any issues
Yes
