Activity

Overview

Activity is an API which records a user’s activity history. The recorded activity is displayed in time series on the user’s friends’ My Page.

This API is included for the sake of maintaining compatibility with platforms for feature phones in Japan. Users’ activities are not actually displayed.

- If you want to send Activity at HIGH priority, use the Activity Service and not the Activity API.
When specifying multiple mediaItems in series, only the first image in the series will be displayed on mobile devices.
The Activity API will return a 403 response code if the user does not have the application in question installed.
