Commerce

Your cart. Your checkout. Our price.

We're not trying to be your store. The seam between what a shopper builds and what your platform charges for is the whole engineering problem, and it's where most of our care goes.

Live in production

In production: the Shopify app end to end, from install to the customizer on your product page and the design landing in your cart with its signed price.

Every design a shopper saves gets a price computed on our server and a signature over the design, its total and its selections. The cart line carries the design code, a thumbnail and a summary anyone can read, while the design itself stays the source of truth. When the order arrives, that signature is verified before anything reaches production.

This is what stops the oldest trick on the internet, editing a price in the browser, from working. It's also what lets your fulfilment keep running on the platform you already use.

Connecting a store is an install, not a project. The app block puts the customizer on your product page, and the last step adds the design to the cart you already run.

The cart references the design. It doesn't replace it.

What you get

  • Signed prices. HMAC over the design, the total and the selections. Re-verified at intake.
  • Order intake. Match the order to its designs, then start production work.
  • Stored first, forwarded second. An integration going down slows an order. It never loses one.
  • Encrypted at rest. Store access tokens are encrypted in our database, not merely hidden.
