API basics

Action	Method	What happens
Create	`POST`	Returns `201 Created` with the new record's `id` and `uri`.
Read	`GET`	Returns the record. Add `?expand=true` on a business to get its full details. See Query Parameters.
Update	`PATCH`	Changes only the fields you send. Services are turned on and off with `PATCH`.

PCE creates every ID. Store the IDs it returns. For what each ID prefix means, see Businesses.

The cross-cutting conventions live on their own pages.
