Just to be clear. You have somebody from within QB clicking a link, that will send them to an external webpage. Before they leave you want a checkbox in QB to be checked, AND when they arrive to the new location (website) you want some of the fields to be pre-populated from information from QB?
If that is correct...
Then you would need to make a formula url button. The first part of the button would be a API_EditRecord call, and the Redirect (RDR) would be to the external website.
As far as pre-populating some of the information, most websites don't have that functionality built in by default. If was a special thing added to QB to allow for that.
What website are you going to? Do you know how to 'inspect' the webpage? You might be able to identify the equivalent f 'field IDs' in the external website.
