A couple of lines of JSTON code for Google Sheets

I am working on Google Sheets and am making JSON requests which give back multiple results.

This is the code I am using:

Result_a

=ImportJSON(CONCATENATE("[url removed, login to view]",C2,"&field_a=",A2,"&field_b=",B2,"&api=",$G$6),"/result_a","noHeaders")

Result_b

=ImportJSON(CONCATENATE("[url removed, login to view]",C2,"&field_a=",A2,"&field_b=",B2,"&api=",$G$6),"/result_b","noHeaders")

Part 1

I need to be able to streamline the above process, since it is calling the same JSON database each time for each result, I want to be able to get all the Results with just one call, and have each result (result_a, result_b, result_c etc.) displayed on the same row but in seperate columns.

Part 2

One of the results has multiple lines, and this is breaking the spreadsheet, I need that result to just return the first line and ignore the rest
