Q&A: JSON Deserialization in Apex – Do You Need All Fields in the Wrapper Class?
💬 Welcome back to Code With Sally – today’s video is a special Q&A edition!
❓ One attendee asked:
*“Do I have to include all the fields from a JSON response when creating a wrapper class in Apex?”*
🎯 In this short, focused video, we’ll explore:
Whether it's okay to skip some fields when deserializing JSON
What happens when a field is missing from the wrapper
How to design minimal and effective Apex wrapper classes
Why field *names must match* exactly to be deserialized
💡 We use a real JSON response from a country API and test:
A full wrapper class
A version with *only one* field
A version with *select fields* (like `capital`, `currencies`, etc.)
A version with a *mismatched field name*
