Getting Supported Messenger Extensions SDK Features

Features of the Messenger Extensions SDK available in the webview vary depending on what version of the Messenger bot the webview is opened in. For this reason, it is important to check that the feature you are using is available when the webview is opened.

To do this. you can call getSupportedFeatures() to get an array of features that are supported on the current client. If a feature you depend on is not available, you can use this opportunity to fail gracefully with a message telling the user to upgrade.

Supported Features

The following Messenger Extensions SDK features are available in the webview:

Feature	Description
`payments`	Whether payments is supported on this client.
`sharing_broadcast`	Using `beginShareFlow()` to open a broadcast flow will work on this client.
`sharing_direct`	Using `beginShareFlow()` to share to the current thread will work on this client.
`sharing_open_graph`	Sharing open graph messages is available.
`context`	`getContext()` is available in the webview.

Example Request

For a complete list of method parameters, see the getSupportedFeatures() Reference.

MessengerExtensions.getSupportedFeatures(function success(result) {
  let features = result.supported_features;
}, function error(err) {
  // error retrieving supported features
