In one embodiment, a method includes determining a reliability score for multiple message aggregators and calculating a rank score for each of the message aggregators. The rank score may be based on a price and the reliability score of the corresponding message aggregator. The method further includes identifying a message type for a queued message. Upon identifying the message type as corresponding to a first message type, the method further includes selecting a first message aggregator of the plurality of message aggregators based on the reliability scores, and upon identifying the message type as corresponding to a second message type, selecting a second message aggregator of the plurality of message aggregators based on the rank scores. Finally, the method includes sending the queued message through the selected message aggregator.

Messaging aggregator selection based on message priority

In one embodiment, a method includes receiving a registration request from an application running on a client system. The registration request includes a messaging token associated with a message-distribution server. In response to the received registration request, the messaging token is registered to a user profile on a social-networking system. A push notification is generated for display at the client system. The push notification and the messaging token are sent to the message-distribution server, where the messaging token identifies the client system to the message-distribution server for delivery of the push notification.

Providing notifications on online social networks

In one embodiment, a method includes providing an application programming interface (API) to an application running on a client system. The API is provided based on a user of the client system being logged in to a social-networking system on the application. A first request is received from the application, and the first request includes a new messaging token and a request to register the new messaging token to a user profile of the user on the social-networking system. A verification token is sent to the application. A second request is received from the application, and the second request includes the verification token and context information of the application. The second request is sent by the application using the API. In response to the received requests, a registration of the user profile is updated by discarding a previously-registered messaging token and registering the new messaging token to the user profile.
