Hello @VCIH ,
I too am looking into a solution for this same exact situation. Our system also allows a Parent SKU to be submitted to the Fulfillment System, which then has a feature that understands how to split the Parent SKU into the actual shippable SKUs for fulfillment. We have a number of scenarios where we need to submit back to Shopify multiple Tracking Numbers for a single fulfillment.
Our team is working on updating our plugin to the new FulfillmentOrders API. While looking for a solution I ran across this Shopify thread where a user named ShopifyDevSup mentioned that the dev team has plans to update the REST API to once more allow multiple tracking numbers.
I’m hoping this is still Shopify’s plan.
Were you able to find a workaround? Did you end up partly using GraphQL to accomplish this part of your requirements?
I’d be interested to know what you and your team figured out on this.
Sincerely,
Kevin
