A method includes receiving a subscription request to obtain notifications of events pertaining to the data file that has been previously uploaded by a user account associated with a user device and stored at the cloud-based file system. The subscription request identifies a destination address for the notifications generated in accordance with the subscription request and one or more events, among multiple events, corresponding to the data file that are to prompt the notifications to be transmitted to the destination address associated with the networked device. The method includes determining that the subscription request is authorized, and identifying an occurrence of an event from the one or more events specified in the subscription request and involving the data file. The method includes transmitting to the destination address a notification indicating the occurrence of the event involving the data file.

Systems and methods for providing notifications of changes in a cloud-based file system

A subscription request to obtain notifications of actions pertaining to the data file that has been previously stored at the cloud-based file system is received. The subscription request identifies the networked device and a set of actions to the data file that are to prompt the notifications to be transmitted to the networked device. An occurrence of an action is identified from the set of actions specified in the subscription request and involving the data file. Responsive to identifying the occurrence of the action from the set of actions involving the data file and in view of the subscription request identifying the networked device, a notification indicating the occurrence of the action involving the data file is transmitted to the networked device.

A cloud-based file system receives a subscription request associated with a networked device and identifying a set of one or more resources of the cloud-based file system and a set of one or more resource modifications. The cloud-based file system determines whether the networked device is authorized to access the resource, and, if so, records a subscription based on the subscription request. In response to a user, an application, or other suitable entity making a modification in the set of modifications to a resource in the set of resources, the cloud-based file system generates a notification to the networked device and to other networked devices with subscriptions that include the modification to the resource. The notification may identify the subscription with which the notification is associated, provide information identifying the modification, or provide other suitable information.

A method for notifying and tasking computer applications hosted by an application execution system by computer applications external to the application execution system is provided. An external computer application may use an external Task queue API to add tasks to the internal application's task queue. The internal application can then see the tasks and act upon the tasks at a convenient, non-busy time for the internal application. An intermediary subscription system may manage an internal application's event subscriptions. When an event occurs, the intermediary subscription system may add a task to the subscribing internal application's task queue. A second intermediate system manages the access control list of an internal application's task queue. This system restricts access to the task queue to only those external applications that are explicitly granted permission in the internal application's task queue configuration file.
