Automatically loading a URL without a user-initiated action is generally discouraged UX - and technically prohibited by browsers in many cases.
HapYak annotations don't have the capability to load a URL without a user action. However, If you're technically inclined, you can do this yourself with our API. You would create a javascript listener for the video-complete event, then perform the desired action.
If you decide to take that approach HapYak can provide some code examples to help.
Here's a working example:
http://jsbin.com/wilaq/1/edit
At the end of the video it auto navigates to hapyak.com
Here are the important lines of code:onTrackingEvent: function(data) {
if (data.event==="Player Action" && data.properties.Action.indexOf("End")===0) {
window.location.href = "http://corp.hapyak.com"}}
Note: this even works on an iPhone (even when the video is playing in the native QuickTime app).
