A developer wrote this OAuth 2.0 token request:

POST /token
Content-Type: application/json
{"code": "abc123"}

Why might this request fail?

ABecause the token endpoint URL is incorrect

DBecause the client credentials are missing

Step-by-Step Solution

Solution:

Step 1: Check required parameters for token request
OAuth 2.0 token requests require client credentials along with the authorization code.
Step 2: Analyze given request
The request only sends the code, missing client ID and secret, so it will fail.
Final Answer:
Because the client credentials are missing -> Option D
Quick Check:
Missing client credentials = request fails [OK]
