03: The Mailroom (POST)

Dispatching structured data packages to the server using JSON payloads.

POST Request Architecture

When you need to send complex data to a server—such as submitting a new project suggestion—you use a POST request. Unlike GET, the data is not in the URL; it is contained in the Request Body. To ensure the server processes this package correctly, we must define the Content-Type: application/json header.

Postman: Raw Body Configuration

In a professional environment, we use Postman to test POST payloads without a UI. Replicate this lab:

  1. Set Method to POST
  2. URL: https://ohagan.au/api/training
  3. Go to the Body tab and select raw.
  4. Change the type dropdown (usually 'Text') to JSON.
  5. Paste your JSON object and click Send.

  "auth": "Verified"
