Previously each tracking code could be added to an order manually but with the new Tracking Code Bulk Uploader you can add many tracking codes at once.
Just select Upload Tracking option from the Shipments menu and follow the instructions.
You can cut and paste data from your computer straight into the Bulk Upload form.
Select your data from your source (see sample data below)
And then Cloud Commerce Pro validates the data and if correct it will let your proceed to add the tracking codes.
