You’ll need to understand fulfillment services on Shopify and how they work with fulfilling an order and if thats the right choice for your app. Theres some really good docs on this here About fulfillment services
Thank you for your reply. I have seen the lifecycle of fulfilling orders, but I encountered an issue at the merchant’s step. I am unable to see the Request fulfillment button on the store’s order details page to initiate fulfillment. Do you have any excellent documentation to share about this button
