What's Changed
In the Messaging API, we've added a new endpoint that allows you to [display a loading animation](https://developers.line.biz/en/reference/messaging-api/#display-a-loading-indicator). After your LINE Official Account receives a message from a user, the response may takes some time due to message preparation or reservation processing. In such cases, you can visually tell the user that you want them to wait by displaying a loading animation.
