We have a live payment app with shopify. Shopify is sending a payment request to app provider server and on it, there is cancel_url like this: “https://my-test-shop.com/1/checkouts/4c94d6f5b93f726a82dadfe45cdde432” but here, we are not abel to send a error message along with the cancel_url
can you please guide us, how can we add a error message to cancel url or how can we send a error message to customer where there is any error happened on payment app or transaction.
