How can we edit JSON + HTTP Post Request + Format body + New Line


I am trying to format JSON body while posting it to an endpoint. The posting is successful. I am not able to format the JSON body into new lines.

Can any one help me with this ?

Sample JSON:

“{”“tId”" : “”“+I_Id+ “””,““Num”” : “”“+LicNum+”“”,““State”” : “”“+State+”“” ,““First”” : “”“+FirstName+”“” , ““Middle”” : “”“+MiddleName+”“” ,““Last””: “”“+LastName+”“”, ““LicType””: “”“+LicType+”“” } "
