Poptin

Poptin>Zap>Marketo

you should be able to leverage APIs to do this with Zap as a router/processor. Their docs should be clear enough.

Ugh, another service that doesn't really understand what "integrating" with Marketo means (Unbounce is another one).

A: You can use Zapier (which we are trying) to connect Poptin direct to Marketo so that leads from people who pass through gates on their pop-ups get created as new leads or update lead information. What I lack is a way to source that the person came from Poptin.

Can you add a hidden field to the form, or some other marker of the source? If you can't, you're out of luck, because if they're passing through your data using the old lead API (shudder) there's no way to add identifying marks to the call itself.

Have you asked them how they stop people from using up all your API calls?  I really detest when services act like they aren't creating a DoS vulnerability.

B: Because Poptin sits on top of my website and is not a link native to the site, Marketo isn't registering Poptin activity, like downloading an e-book through a pop-up, as an activity and I don't know how I would go about trying to log that activity.

Are you sure that's it, or is it that the Poptin form fillout doesn't associate the Munchkin web session, so the clicks are in fact logged, just to an anonymous lead?
