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:

功能	说明
`payments`	此客户端是否支持支付功能。
`sharing_broadcast`	使用 `beginShareFlow()` 打开广播流程在此客户端上有用。
`sharing_direct`	使用 `beginShareFlow()` 分享到当前对话在此客户端上有用。
`sharing_open_graph`	分享开放图谱消息功能可用。
`context`	`getContext()` 在网页视图中可用。

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
});
