I've been following Keith Palmer tutorial for linking Quickbooks to PHP. I used the sample code (example_app_ipp_v3/index.php) and it all works great.
The problem how I can set up production keys so I can use my actual company data not sandbox data.
In simple words I've got development keys which I used for sandbox data. How shall I go on about syncing company data. Where shell I start form.
Many Thanks,
