Rest API - HTTP Methods

A REST API uses PUT to replace a nested resource like /users/5/address. The original address is {"street":"1st Ave","city":"NY","zip":"10001"}. The client sends a PUT with {"street":"2nd Ave","city":"NY"}. What will be the final address stored?

A{"street":"2nd Ave"}

B{"street":"2nd Ave","city":"NY","zip":"10001"}

C{"street":"1st Ave","city":"NY","zip":"10001"}

D{"street":"2nd Ave","city":"NY"}

Step-by-Step Solution

Solution:

Step 1: PUT replaces the entire nested resource
The new address fully replaces the old one, so missing fields are removed.
Step 2: Missing "zip" field is deleted
Since "zip" is not in the PUT body, it will be removed from the stored address.
Final Answer:
{"street":"2nd Ave","city":"NY"} -> Option D
