The Shopify order ID is an internal identifier used by Shopify to track orders. It's different from the order name (or number), which is customer-facing and can be customized in your Shopify admin.
To find it, open the order in your Shopify admin and look at the URL. The order ID is the number at the end.
For example, the order ID is 1234567890 at the end of the URL: https://yourstore.myshopify.com/admin/orders/1234567890.
