Hello,
I have a custom installation page (iparams.html), inside this, I’m calling API to push data into the DB and I meet CORs issue. I have the same API calling in a serverless app, and it works because I have added the white-listed domain in manifest.json. However, the white-listed domain list doesn’t seem to have affected the App Installation.
So how can I call the API inside the Custom App Installation without meeting CORs Issue?
Thank you
