When a shopper completes personalization, Composerie saves the design state and submits the selected Shopify variant with protected Composerie references. Those references let the later order resolve the exact design revision used at checkout.
What travels with the cart line
The handoff associates the cart line with the saved design, preview, publication revision, selected variant, and any priced add-ons. Technical Composerie properties are not customer instructions; they are the references used to verify and rebuild the ordered result.
The item’s total surcharge is signed so the worker can detect a changed or inconsistent add-on amount before production.
What you see on the order
The Shopify order contains those references. In Composerie, its order page shows the customer proof and personalization summary. The Production card displays the route and recorded file details.
Open View proof on the order to see the customer result that production is bound to. What an order page shows walks through the rest of that page.
Where do I review the customer's design?
Open the Composerie order and select View proof on the line item.
Why are there technical Composerie properties?
They identify the saved design, publication revision, preview, and pricing data required for a trustworthy production handoff.
Are normal products affected?
No. Composerie adds its design handoff only to products published with Composerie personalization.
