Parameters

The Parameters object is a JSON-formatted object containing context information specified by the developer. The Parameters object is specified in a Visualforce page by using the parameters tag in the apex:canvasApp component, or in a Chatter canvas feed item by using the parameters variable when creating the feed item.
