wpForGlass relies on Google’s Mirror API to get its work done. The Mirror API is a web-based service for Glassware that uses web services as the layer to build Glassware on top of.
It’s important to note how wpForGlass and the Mirror API content sharing workflow actually works:
From a technology perspective what this means is that the time it takes for a post to show up on your blog is dependent on how long it takes for the Mirror API to process your media, and send your server a timeline notification. In our experience, it’s usually within a few minutes for images. Video can take longer because a video needs to upload to Googles servers first, where it is then processed.
