Common Operations

The SKU.io API has thousands of endpoints, but most integrations only ever touch a few dozen. This page is the shortlist — the create / read / update calls you'll reach for first in each domain, with the exact method, path, and required token scope.

Every operation name links to its full reference page (parameters, request body, response schema, and a live example). Each domain heading links to its section in the API Reference, where you can browse the complete endpoint list.

Start with the Quickstart to make your first authenticated call, then skim API Conventions for the /api vs /api/v2 split and the response envelope. Scopes below (e.g. orders:write) map to token permissions — see Authentication.
