The Notification Pipeline

The notification pipeline is a websocket connection that broadcasts the events of a hub or an account. It broadcasts JSON messages over the socket, with a header field that can be used to determine the event that took place.

Attributes
  • topic
    string

    A header topic, for the full list see the table included on this page.

  • object
    object

    The ID of the notification and potential state and error information.

    Show child fields
  • context
    object

    The context associated with this notification including but not limited to data on the hub, account, environment, DNS zone, cluster, or containers associated with this notification.

    Show child fields

Authenticating

Connecting to the websocket is a two step process.

First you authenticate against one of the two following endpoints:

/v1/channels/account/notifications
/v1/channels/hubs/current/notifications

This returns a URL and a token you can use to create a websocket connection to the notification pipeline.

If you're using the TypeScript client this is automatically handled for you. The function calls are shown in the example area. If you're not using the TypeScript client and want to pass credentials to your websocket client of choice, you can use cURL to authenticate and pass the credentials to your client.

The return from the authentication request will be a token, and the token will need to be appended to the URL as a parameter to complete the websocket connection.

Connecting to the Notification Pipeline

There are two pipelines you can connect to, Hub and Account. The account pipeline will send information about events happening that relate to account state, new and updated hubs, and account errors, while the hub pipeline will send notifications about all other available events happening on the hub. The notification pipeline will only send meta information. It's at your discretion to use that information and decide whether to make a follow up API call for the rest.

It is not possible to make websocket connections in cURL without the use of a third-party tool.
