# Content The `content` object specifies which components you want to render within the `canvas` of your apps `card` or `frame`. There's a small difference to note between a static and a live canvas: - **Static**: you can provide the `content` object within the `canvas`. - **Live**: you will need to provide a `content_url` for us to POST a request to within the `canvas`, and subsequently respond with the `content` object there. ```json { "content": { "components": [ { "type": "text", "text": "This is your updated canvas", "align": "center", "style": "header" } ] } } ``` | Key | Type | Description | | --- | --- | --- | | components | array[object] | The list of components to be rendered within a card or a frame. See our components further in this reference. |
