choose 'Edit cart' in 'Page to show link' (the only other option I have is 'order completed')
I don't see any callbacks happening with this process and it appears to me I'm missing something since with only two options there doesn't seem to be the granularity needed to 'insert yourself anywhere in the checkout process' as the documentation suggests.
Can anyone give me any clues on what needs to be done here? My goal is simple...
the user clicks on 'Continue to shipping' while checking out
the embedded app calls my react backend
the front end shows my page in the iFrame to the user.
