Rest API - Request and Response Format

You want to send a nested JSON object in the request body to create a user with address info:

{
  "name": "Eve",
  "address": {
    "street": "123 Main St",
    "city": "Townsville"
  }
}

Which Content-Type header and body format should you use to ensure the server correctly understands this nested data?

AContent-Type: application/json with the JSON body as shown

BContent-Type: text/plain with JSON body as string

CContent-Type: application/x-www-form-urlencoded with nested keys

DContent-Type: multipart/form-data with JSON inside a file

Step-by-Step Solution

Solution:

Step 1: Identify correct header for nested JSON
Nested JSON requires application/json Content-Type so the server parses the structure correctly.
Step 2: Evaluate other formats
text/plain treats body as plain text, application/x-www-form-urlencoded does not support nested objects well, and multipart/form-data is for files, not nested JSON.
Final Answer:
Content-Type: application/json with the JSON body as shown -> Option A
