Currently my supplier sends me an email with the PO number (currently my Shopify order number but this can be anything I send them), and the shipping tracking number.
I’m trying to forward these emails to a parsing service which will then update the tracking number for that order via REST http webhook. I’m noticing that for the tracking_ info command, I need the fulfillment _id.
Given this workflow will ALWAYS be related to a specific Shopify location, is there some way to structure the API call to work when I only have the order-number as a reference, such as adding additional static parameters to the REST command to associate the order number and tracking number to that specific location_id’s fulfillment?
Alternately I could just start sending the order to the supplier with the reference being the fulfillment ID but I worry about this method as introducing potential for failures-by-typo from using this longer string versus the 4-digit order number.
