Polling service

1. A method for polling federated services for notifications, comprising:

requesting an access token for a federated service from an authentication service;

receiving the access token from the authentication service;

sending a query to the federated service for a notification, the query comprising the access token;

receiving the notification from the federated service;

identifying a user-designated client application based at least in part on an authentication credential stored in association with the user-designated client application; and

sending the notification to an instance of the user-designated client application executing on a client device.

2. The method for polling federated services for notifications of claim 1 , wherein the user-designated client application has been previously registered with a polling service.

3. The method for polling federated services for notifications of claim 1 , further comprising sending the notification to an email address previously registered with a polling service.

4. The method for polling federated services for notifications of claim 1 , wherein the request for the access token comprises an identifier for the federated service.

5. The method for polling federated services for notifications of claim 1 , wherein the request for the access token comprises a user identifier for a user account associated with the access token.

6. The method for polling federated services for notifications of claim 1 , wherein the access token was previously provided by the federated service to the authentication service in response to a successful authentication of the authentication service with the federated service on behalf of a user.

7. The method for polling federated services for notifications of claim 1 , wherein the access token is valid for a pre-defined period of time.

8. A system for polling federated services for notifications, comprising:

a computing device comprising a processor and a memory;

machine-readable instructions stored in the memory that, when executed by the processor, cause the computing device to at least:

request an access token for a federated service from an authentication service;

receive the access token from the authentication service;

send a query to the federated service for a notification, the query comprising the access token;

receive the notification from the federated service;

identify a user-designated client application based at least in part on an authentication credential stored in association with the user-designated client application; and

send the notification to an instance of the user-designated client application executing on a client device.

9. The system for polling federated services for notifications of claim 8 , wherein the user-designated client application has been previously registered with a polling service.

10. The system for polling federated services for notifications of claim 8 , wherein the machine readable instructions, when executed by the processor, further cause the computing device to at least send the notification to an email address previously registered with a polling service.

11. The system for polling federated services for notifications of claim 8 , wherein the request for the access token comprises an identifier for the federated service.

12. The system for polling federated services for notifications of claim 8 , wherein the request for the access token comprises a user identifier for a user account associated with the access token.

13. The system for polling federated services for notifications of claim 8 , wherein the access token was previously provided by the federated service to the authentication service in response to a successful authentication of the authentication service with the federated service on behalf of a user.

14. The system for polling federated services for notifications of claim 8 , wherein the access token is valid for a pre-defined period of time.

15. A non-transitory computer-readable medium for polling federated services for notifications, the non-transitory computer-readable medium comprising machine-readable instructions that, when executed by a processor, cause a computing device to at least:

request an access token for a federated service from an authentication service;

receive the access token from the authentication service;

send a query to the federated service for a notification, the query comprising the access token;

receive the notification from the federated service;

identify a user-designated client application based at least in part on an authentication credential stored in association with the user-designated client application; and

send the notification to an instance of the user-designated client application executing on a client device.

16. The non-transitory computer-readable medium for polling federated services for notifications of claim 15 , wherein the user-designated client application has been previously registered with a polling service.

17. The non-transitory computer-readable medium for polling federated services for notifications of claim 15 , wherein the machine-readable instructions, when executed by the processor, further cause the computing device to at least send the notification to an email address previously registered with a polling service.

18. The non-transitory computer-readable medium for polling federated services for notifications of claim 15 , wherein the request for the access token comprises an identifier for the federated service.

19. The non-transitory computer-readable medium for polling federated services for notifications of claim 15 , wherein the request for the access token comprises a user identifier for a user account associated with the access token.

20. The non-transitory computer-readable medium for polling federated services for notifications of claim 15 , wherein the access token was previously provided by the federated service to the authentication service in response to a successful authentication of the authentication service with the federated service on behalf of a user.
