Dear folks,

I am developing an embedded app which lets store owners quote our shipping rate and create shipping labels via our APIs.
We have experienced the CORS Policy issue, and the screenshot is attached. I did try all the solutions from this forum and have yet to be successful. Can someone help point out a lead, demo code or document? I really appreciate any help you can provide.
