Order from cart permalink with access token is not attributed to the sales channel

Topic summary

A developer is experiencing an issue with Shopify’s Cart Permalinks with Access Token feature for sales channel attribution.

Core Problem:

  • Orders are correctly attributed to the sales channel when customers complete checkout without modifications
  • Attribution fails when customers modify their cart (change quantities, add products) before completing the order
  • The same issue occurs when users are redirected directly to checkout, then navigate back to cart to make changes before returning to checkout

Impact:

  • The sales channel attribution (access token) is lost after cart modifications
  • This creates tracking problems since the developer can only read orders from their own sales channel due to Shopify’s sales channel policies
  • Conversion tracking information appears to be missing in these scenarios

Status: The developer is seeking community input on whether others have encountered this issue and potential solutions.

Hello Shopify Community,

Does anyone use Cart Permalinks with Access Token to attribute orders to their sales channels app?

Everything works fine if customer place order without any change but if customer change something in the cart (quantity, add more products, etc.) order is not be attributed to my sales channel.

Conversion tracking information are there, just the sales channel attribution (access token) is missing.

This is an issue as we are allowed to read only our own orders because of Shopify’s policy for sales channels.

PS The same issue is if we redirect users directly to checkout and then customers go back to cart to modify something and go back to checkout.
