Rest API - HTTP Methods

You have an API where PATCH /profile/123 updates only the email field of a user profile, while PUT /profile/123 replaces the entire profile. Why is it important to choose PATCH over PUT when updating just one field?

APATCH is faster because it sends less data

BPUT can accidentally erase other fields if not included

CPATCH creates a new profile instead of updating

DPUT is only for deleting resources

Solution:

Step 1: Understand the difference between PUT and PATCH
PUT replaces the entire resource, so missing fields get erased. PATCH updates only specified fields.
Step 2: Analyze the risk of using PUT for partial updates
If you use PUT but omit some fields, those fields may be removed unintentionally.
Final Answer:
PUT can accidentally erase other fields if not included -> Option B
Quick Check:
Partial update safe = PATCH, full replace risk = PUT [OK]

Quick Trick: Use PATCH for partial updates to avoid data loss [OK]

Common Mistakes:
