I have an ERP system on an IBMi, I currently retrieve orders from Shopify via an API (you call it an App, I think). All I want to do is tell Shopify they shipped and add a tracking #.
So, I believe I need to use the fulfillment process, if there’s a different way, please let me know.
How/where does a fulfillment # get created (is it created by Shopify?)
Does anyone have a simple diagram of the processes (APIs) needed to handle this.
If you have the order and tracking details available in CSV format, you can utilize an app to import them back to Shopify.
Alternatively, you can utilize the Shopify Fulfillment APIs to automate the process. You may refer to the Shopify developer documentation for more information.
