Dynamic Data Creation in Salesforce From Json Data Without Using Wrapper Class
Generally for Json data insertion from external system to Salesforce, we use apex rest class and wrapper class for every object. I had a requirement to insert around 40 SF objects data from the Json data. To accomplish this requirement, I created a dynamic class, where we can insert Json data for N number of objects.
The advantage of this class is don’t need to change anything in class, If our number of object will increase or any field name will change or any field type will change. We need to change only in Custom Settings.
So, here is my article on dynamic data creation in Salesforce from json data without using wrapper class. In this article I’m going to pass Json data of Accounts & Contacts objects.
For external system data I’ve created external Id in both Account & Contact objects.
Account Object External Id Custom Field:
Contact Object External Id Custom Field:
To save SF object and Json Object information, We need to create a Custom Settings for objects.
Here is the Custom Setting Object (Json Object Mapping):
Custom Setting Object (Json Object Mapping) Fields:
Custom Setting Object (Json Object Mapping) Records For Account & Contact Objects:
To save SF field and Json field information, We need to create a Custom Settings for fields.
Here is the Custom Setting Object (JSon Field Mapping):
Custom Setting Object (Json Field Mapping) Fields:
Custom Setting Object (Json Field Mapping) Records For Account & Contact Objects:
Sample Json Data of Accounts & Contacts Objects:
{
"Account_List": {
"Account": [{
"External_Id": 833993,
"Account_Name": "John"
},
{
"External_Id": 833994,
"Account_Name": "Peter"
}]
},
"Contact_List": {
"Contact": [{
"External_Id": 100001,
"Account_External_Id":833993,
"First_Name":"Biswajeet",
"Last_Name": "Samal"
},
{
"External_Id": 100002,
"Account_External_Id":833994,
"First_Name":"Abhijeet",
"Last_Name": "Samal"
}]
}
}
Dynamic apex rest class:

for(Integer i=1; i <= objectMappingList.size(); i++){

To test the rest class, here is the snapshot to call the apex rest class from Workbench Rest Explorer.
After successfully execute the rest class with Accounts & Contacts Json data.
Created Account Records:
Created Contact Records:
Note: This is the sample class. For better performance and to accomplish your requirement you can modify this class.
