Piwik Analytics API - Get Current Visitor's Insights

Hello,

I’m totally new to Piwik Analytics API, actually I’m not a developer. I’m looking for ways to get, on my website, “insights” from my current visitor in a way I can customize content. I think I could use things like keywords the visitors used to get into my site, and keywords from the pages they visited before.

My budget for the project is zero, but I learn quickly, so please, if you know the steps I must follow to get there, I would really appreciate to hear from you!

Best regards,
Bruno Moreira Guedes
