The defined structure of the data body sent in an API request or response, specifying field names, types, whether each is required, and how they nest.

Two heavy words for the shape of a form, where "payload" borrows from ordnance and cargo to describe two kilobytes of JSON containing a name and a date.

• Weight by Vocabulary: "Payload" makes a routine request sound like something being delivered to a target.
• Standard Work Renamed: Defining field names is ordinary API design, described in language reserved for logistics operations.
• House-Cleaning Reality Check: Like handing over a shopping list and calling it a "grocery payload schema."

Archer (2010s) where a routine envelope handoff is briefed in full tactical operations language, complete with code names and mission designations.

“Ensure every integration conforms to the canonical payload schema before deployment.”

“The API expects a JSON object with a client ID, a date, and an amount, and rejects anything else.”
