I am using LinkedIn button to help sign-in on one of my forms. Is there a way to capture how many people click on the button? I want to gauge the engagement and not just form submits. Any idea how I can do that?

Deepa, I think Scott's comments don't relate to your question, since you're talking about social sign-on.
I think you want to look at https://nation.marketo.com/ideas/2949#comment-21350, though it's possible the info is outdated (the post was from 2013). Let me know how it goes.
