I need a way that I can print shipping labels through wix without integrating an external shipping app. My problem is that I use Canada Post Lettermail - Oversized. All external apps use pricing for packages. It is very time consuming to write every shipping label by hand. I found instructions for a code to do this https://www.wix.com/velo/forum/tips-tutorials-examples/how-to-create-printable-shipping-labels-for-orders-in-wix-using-wix-code?origin=auto_suggest But I can’t get it to load my shipping labels. I am not familiar with coding so this is very difficult for me.
I keep getting this error.
Can someone help me figure this out?
