Can ShowPad for sales enablement to be integrated with Marketo?
Apparently, the sales people can generate unique pages for their prospects and track activity.
Could it possible to integrate this using REST API or Webhook?
You should be extremely specific about what you mean by "integrated" -- the term has no inherent meaning when you're talking about two platforms with expansive, but not overlapping, feature sets.
From a cursory look at the ShowPad API (which is more of an admin API) it's clear there's no built-in integration between their email tracking features, for example, and any outside platform. But since they also allow you to build and upload packaged HTML/JS web apps as a content type, one can't say you can't integrate web-side Marketo features like Munchkin -- as you could with any web app.
There is an integration - its a purchased addon but does allow you to integrate (i'm currently going thru those steps).
Its setup via the rest API and custom activities.
Didn't exist 2 years ago, of course!
How does it meter API call usage to not DoS your other integrations?
