I am using this query using REST API to get Apex Classes
SELECT Id,Name,NamespacePrefix,Status FROM ApexClass. However this returns all my classes as well Manage package classes.
How can I Identify that which classes are from my organization?
Is there any way to get Namespace of my Organization using REST API so that I can differentiate ?
I tried to parse response after OAuth however it does not have organization Namespace in it.
