How to contact with Marketo support?

Hi Support,

I have some document issue.  
We found the "Web Service Api"  type of the "Campaign is Requested" triger is not required when to invoke the "Request Campaign" operation. We found the "Sales Insight" type triger is also worked well.

But the document says clearly , pls. check the words blow which is  referenced from the API document.
So we are going to confirm with your side wheather this is a document mistake.

"This function runs an existing Marketo lead in a Marketo Smart Campaign.  The Smart Campaign must have a “Campaign is Requested” trigger with Web Service API source"  

You should go to Support at the top of the screen and create a Case.

Or call them. The number is in the same place.
