Friendly Warning: welcome to developer territory.
You will have a lot of fun if you are comfortable with HTML, Javascript and CSS, or have a friend / colleague that is. If not, you may have a bad time.
If you are a real do-it-yourselfer and want to learn yourself, we highly recommend first taking Codeacademy's free HTML/CSS and JavaScript courses.
HapYak reports and analytics are a powerful tool to understand how individual and groups of viewers are interacting with and experiencing your video.
We track every individual viewer as they watch the video. And you can identify exactly who these viewers are, for example by username or email address (where email address is passed in as userId). Here's how to do it.
1. Pass in a userID, username or email address
You can do so via the HapYak Embed API or by appending the parameter to the URL where the video is embedded. The parameters are viewable on our Docs.
2. Add a Sign In Annotation (aka "Lead Wall", "Turnstile", "Gate")
