Body
ELI5 — The Vibe Check
The body is where the actual data lives in a request or response. It's the message inside the envelope. GET requests usually have no body (you're just asking for data), but POST and PUT requests have a body containing the data you want to create or update.
Real Talk
The request or response body is the data payload transmitted after the headers. Request bodies are used with POST, PUT, and PATCH to send data to the server. Response bodies contain the returned data, error messages, or resources from the server.
