Rest API - API Documentation

You see this endpoint documentation snippet:

{
  "endpoint": "/items",
  "method": "POST",
  "parameters": {
    "name": "string",
    "quantity": "integer"
  },
  "response": {
    "201": "Item created"
  }
}

But the API returns a 400 error when you send the request. What is the most likely mistake in the documentation?

AThe endpoint URL is missing a trailing slash

BThe HTTP method should be GET, not POST

CParameters should be inside a "requestBody" section, not "parameters"

DThe response code 201 is incorrect for creation

Step-by-Step Solution

Solution:

Step 1: Understand POST request structure
POST requests usually send data in the request body, not as URL parameters.
Step 2: Check documentation structure
Parameters listed under "parameters" implies URL/query parameters; for POST data, it should be under "requestBody".
Final Answer:
Parameters should be inside a "requestBody" section, not "parameters" -> Option C
Quick Check:
POST data = requestBody, not parameters [OK]

Quick Trick: POST data goes in requestBody, not parameters [OK]
