Rest API - Batch and Bulk Operations

You send this PATCH request payload to update multiple items:

[{"id":1,"status":"done"}, {"status":"pending"}]

What is the likely problem?

AMissing 'id' in second object causes update failure or error.

BThe payload is valid and will update all items.

CUsing PATCH instead of POST causes syntax error.

DThe array should be empty for batch updates.

Step-by-Step Solution

Solution:

Step 1: Check each object in payload
The second object lacks 'id', so the server cannot identify which item to update.
Step 2: Understand update requirements
Each update must specify the item to update, usually by 'id'. Missing it causes failure or error.
Final Answer:
Missing 'id' in second object causes update failure or error. -> Option A
Quick Check:
Each update needs an identifier like 'id' [OK]

Quick Trick: Every update object must include an identifier like 'id' [OK]
