I have a need to enhance my conversion reporting for multiple accounts.
So I have many lead-gen type campaigns. The user comes to landing page, fills a form, a regular online conversion is reported to AdWords system with no value. Simple, easy, standard.
However, these leads mature over time and begin to accumulate value. Lead comes in, sales staff qualifies, sale is made, that lead now has a value.
So now I have the need to UPDATE the original valueless conversion to now have a value. Normally we'd collect this information and upload offline conversions but that won't work here. We have to track all form submits AND the future values associated with them.
Obviously, this cannot be done with the interface or editor and the API is the only solution.
I can't find any docs on an update-type function. Does something like this exist? If not, what is the solution to be able to track conversions that update values over time?
