Rest API - Batch and Bulk Operations

Consider this PATCH request payload:

[{"userId":10,"role":"admin"},{"userId":15,"role":"editor"}]

What is the expected server behavior upon receiving this batch update?

AReturn an error because batch updates must use PUT

BCreate new users with the specified roles

CUpdate the roles of users with IDs 10 and 15 accordingly

DIgnore the request because PATCH does not support arrays

Step-by-Step Solution

Solution:

Step 1: Analyze payload
The payload contains multiple objects each specifying a userId and a new role.
Step 2: Understand PATCH semantics
PATCH supports partial updates; here it updates roles for specified users.
Step 3: Evaluate options
Update the roles of users with IDs 10 and 15 accordingly matches expected behavior; others are incorrect due to misuse of HTTP methods or misunderstanding.
Final Answer:
Update the roles of users with IDs 10 and 15 accordingly -> Option C
