Thanks for the quick response Murtza,
We are already tracking how many leads we are injecting into our customer's Marketo instances by storing some information when we insert them. What I'm interested in tracking is what percentage of new leads we are responsible for contributing. This involves knowing how many leads are coming from other lead sources, whatever they may be.
I thought about using the Get Multiple Leads by Filter Type API using Lead Source as the Field but it seems like that API returns an error if there are more than 1000 results, which there certainly will be after a reasonable amount of time. Also, I'm not sure if we could construct a query that says Lead Source != "Our App" to get the number of other leads coming into their system.
Do you know of a way I could measure the percentage of leads we are contributing?
Thanks!
