To efficiently construct and add a JSON object or array to your request body, use XPRIM_JsonWriter.

It's essential that you use XPRIM_JsonWriter when your JSON data is big (instead of directly instantiating multiple XPRIM_JsonObject or XPRIM_JsonArray), as XPRIM_JsonWriter is designed to perform better for big data.

     Define_Com Class(#XPRIM_HttpRequest) Name(#Req)

* Create an XPRIM_JsonWriter to efficiently write JSON data

     Define_Com Class(#XPRIM_JsonWriter) Name(#JsonWriter)

* Set the writer to output the JSON to the HTTP request object

     #JsonWriter.SetOutputToHttpRequest HttpRequest(#Req)

* Start constructing the object

     #JsonWriter.BeginObject
     #JsonWriter.WriteString Name('givenName') Value(#EmpGivenName)
     #JsonWriter.WriteString Name('lastName') Value(#EmpLastName)
     #JsonWriter.WriteString Name('address') Value(#EmpAddress)
     #JsonWriter.EndObject

* Execute the request

     #Req.DoPost Url('http://yourcompany.com/api/hr/employee')
