What information should the workflow read?
Start with the question your support team receives: “Where is my order?” The useful response depends on whether the order is awaiting fulfilment, has tracking information or needs investigation. Payment, fulfilment and carrier delivery are different states.
Shopify exposes tracking details such as a carrier, tracking number and URL through its fulfilment tracking information. Not every record contains every detail. Your response needs a branch for an empty result.
List the fields your connected action actually returns. Do not write a message template around a promised delivery date unless your source supplies a reliable date and your team agrees how to describe it. The order-status reply guide covers the customer-facing wording.
