Chapter 9

Request bodies

The body kind decides the editor and the Content-Type. — 1: Body kind — the editor and the Content-Type follow it — Figure 29: The body kind decides the editor and the Content-Type.

1 picks the kind. The editor below changes with it, and so does the Content-Type Baton sends unless a header overrides it.

Kind	For
none	GET and anything else with nothing to send
JSON	The common case; the editor formats and folds it
Text	Anything you want sent verbatim
Form	`application/x-www-form-urlencoded` rows
Multipart	Rows that may be files — the boundary is Baton’s
Binary	A file sent as-is
GraphQL	Query and variables as two panes — see GraphQL and WebSocket 11

A JSON body takes {{variables}} like anywhere else, so a payload that differs only by an id between environments stays one request.

Note Multipart and binary bodies are encoded before they leave the resolver, and sent exactly as encoded. The browser build sends them through fetch as a single envelope rather than letting the browser rebuild a FormData, so the boundary you see in Sent is the boundary that went out.
