Adding an identifier in the order information in Shopify that is passed to our 3rd party fulfillment center

Question

Would it be possible to have an identifier in the order information that is passed to our 3rd party fulfillment center that would enable them to put an insert in the orders being shipped to different groups of customers? I've heard something about adding tags to orders but I'm still sifting through documentation for this -- hence posting my question here :-)

Answer 1

There's a couple of ways to do it...

You could use metafields: https://shopify.dev/docs/admin-api/rest/reference/metafield

Or you could add an attribute to the properties in line-items itself:

This last way is how we did it with a major retailer - worked a charm!
