I want to configure a jquery progress bar to load from zencoder API notifications about a video conversion. The API sends the notification to a specified URL in the form of json or xml, but I can't figure out where its going if at all. Please help.
You need to specify what notifications you want, and where you'd like them to be sent. The guides on this are really helpful for getting started. In a nutshell, you can have it POST or email a notification for the whole job, individual outputs, or both.
However, these notifications are only sent when a job or output is completed, so it wouldn't help you too much for a progress bar. For that you can query the API for job progress and update your progress bar accordingly.
