# 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.

The following code snippet shows an example of the Parameters object.

```nolang
"parameters":
{
    "inventoryStatus":"Picked",
    "stockPrice":"12.99",
    "count":2, 
    "address":{"street":"1 Market", "city":"San Francisco", "state":"CA"}
}

```
