We’re building a custom app for weight-based shipping, where delivery options and prices depend on the total checkout weight.
No issues calculating weight using checkout/create and update webhooks—the challenge is passing that data to our delivery customization API extension. While we can access the cart, there’s no clear way to identify the checkout session/ID from the extension.
Right now, we store the total checkout weight in our DB using the checkout ID from the webhook as the key. If we could access the checkout ID from the extension, that would solve everything—unless there’s a better approach?
This would allow us to dynamically hide or show delivery options based on weight.
Would love to hear your thoughts—any insights or alternative solutions you’d recommend? Appreciate any input!
