I am having nearly 400+ fields in a object and during callout I have to send this fields in JSON body.
At present I am manually mapping the fields by keeping all the JSON fields in a object.So the clas itself is having nearly 400+ fields
So mapping like this
Health_SBP__c ----> fv_sbp Health_DBP__c ----> fv_dbp ...
Not sure whether my mapping will create any performance issue?. Is there a batter way to map these 400 + fields?
