# Using Streaming API in a Canvas App

Canvas provides an event and methods that enable canvas apps to listen for Streaming API notifications.

- `sfdc.streamingapi`—JavaScript event that you create and associate with a Streaming API channel defined by a PushTopic. See [Using the Streaming API Event](/docs/platform/canvas-framework/guide/canvas-app-streaming-event-code-example.md).

- `subscribe`—Subscribes to the `sfdc.streamingapi` event that you define. See [Subscribing to a Streaming API Event](/docs/platform/canvas-framework/guide/canvas-app-streaming-subscribe-code-example.md).

- `unsubscribe`—Unsubscribes from the `sfdc.streamingapi` event. See [Unsubscribing from a Streaming API Event](/docs/platform/canvas-framework/guide/canvas-app-streaming-unsubscribe-code-example.md).
