One email, then sign in with Lightspeed (X-Series) to approve access to your catalog, stock and outlets. Sign-in links for your order counter go to this address.
One honest note: marketplace orders don't appear on your Lightspeed register — they arrive in your within order counter (we email you and give you a live counter page), and we adjust your Lightspeed stock the moment an order is paid so your counts stay true.
On Lightspeed's Plus plan with a personal access token instead? Use the advanced token path.
