Get Activity Batch

Gets a batch of multiplayer activities for a list of users. This API allows clients and services to get a batch of activities for a list of users. This API can return partial results; any given user will have its complete set of activities, but some users may have no activities at all. If we found activities for a subset of users, we return those. For the users whose activities were not found, we return an empty list for that user. For the users whose activities couldn’t be fetched due to an internal error, we return null for that user; the client should retry the call. In short, a user can have a list of activities, an empty list or null.
