I'm new in Apex and we have a requirement, Need to send a record from Salesforce to an external system using Rest API whenever a record is created in Salesforce, I need to send a couple of SF fields to the external system along with the External system required field's
I created a class that has both JSON generator and HTTP post method however this code is not with only one record, 3.I'm not sure how to create a JSON generator in the apex, struggling with JSON generator for making an HTTP request.
I don't whether I made the correct JSON generator. can you please suggest me easy method with the below JSON body as JSON generator.
I have tried below it throws error that Can not start an object, expecting fields name
