Push Notifications - Download

Ably’s push notification service is currently in beta. As such, the client libraries currently have varying levels of support for push notifications.

Below is a table with the recent status of each library along with instructions on how to install each library. Get in touch if a needed library is missing or you require any assistance.

How to use push notifications with an unsupported client library

As most of the functionality required to manage and publish push notifications is exposed using our documented REST API, if we have not yet added push support to a client library you need, you have two options available to start using push notifications now anyway:

  • Use our client library request method that is provided as a convenience for developers who wish to use bleeding edge REST API functionality without having to handle authentication, paging, fallback hosts, MsgPack and JSON support, etc. themselves. Refer to REST API documentation for a list of push related endpoints
  • Access the REST API directly from your apps or servers

For example, in the Javascript / Node.js library you can obtain a list of all registered devices using the request method as follows:

var ably = new Ably.Rest({ key: key });
ably.request(
  'get',
  'push/deviceRegistrations',
  {limit: 100},
  null,
  null,
  function(err, response) {
    if(err) {
      console.log('An error occurred; err = ' + err.toString());
    } else {
      console.log('Success! status code was ' + response.statusCode);
      console.log(response.items.length + ' devices returned');
      if(response.hasNext()) {
        response.next(function(err, nextPage) {
          console.log(nextPage.items.length + ' more devices returned');
        });
      }
    }
  }
);

Please note that if you want to receive push notifications on a device using an Ably client library that does not yet support push notifications, then please get in touch. Unfortunately, receiving push notifications is platform specific. As a result, adding support is far from trivial.
