Rest API - Versioning Strategies

If a client sends this header:
Accept: application/vnd.example.v2+json
But the server only supports v1, what is the expected behavior?

AServer returns v2 response anyway

BServer ignores version and returns v1 response

CServer returns a 406 Not Acceptable error

DServer returns 500 Internal Server Error

Step-by-Step Solution

Solution:

Step 1: Understand server version support
The client requests version 2, but server only supports version 1.
Step 2: Determine correct HTTP response
Server should respond with 406 Not Acceptable to indicate it cannot fulfill requested version.
Final Answer:
Server returns a 406 Not Acceptable error -> Option C
Quick Check:
Unsupported version request = 406 error [OK]

Quick Trick: Unsupported version request returns 406 error [OK]
