@a0-events

Using Cloudflare Durable Objects we now have the ability to notify browsers and backend about changes to a user's session. This will allow us to implement Single Sign Out, Token Revocation and more...

Getting started

Connecting your Log Stream

As a first step we want to send all of the Auth0 audit logs to our event publisher. In the Auth0 Dashboard under Log Streaming go ahead and create a new Custom Webhook stream with the following settings:

• Name: Auth0 Events
• Payload URL: https://events.auth0a.com/{YOUR_TENANT}/api/publish
• Content Type: application/json
• Content Format: JSON Array

The tenant in the payload URL depends on your actual Auth0 domain and locality. Here are the 5 different options you can use:

Domain	Payload URL
sandrino.auth0.com	https://events.auth0a.com/sandrino/api/publish
sandrino.us.auth0.com	https://events.auth0a.com/sandrino@us/api/publish
sandrino.eu.auth0.com	https://events.auth0a.com/sandrino@eu/api/publish
sandrino.au.auth0.com	https://events.auth0a.com/sandrino@au/api/publish
sandrino.jp.auth0.com	https://events.auth0a.com/sandrino@jp/api/publish

Note: The payload URL currently does not require any form of authorization. That's something we'll want to add later.

That's all there is to it to start publishing events.

Defining an API

In order to receive events our clients (browsers, backends) will need to connect to the stream but they'll also need to authenticate. Start by creating a new API in the Auth0 Dashboard:

• Name: Auth0 Events API
• Identifier: https://events.auth0a.com/api
• Permissions: listen:events:self and listen:events

Sample CLI

A first demo we have is a sample CLI which connects to the stream and displays the events.

Follow the steps described here to run the CLI demo.

Note that we currently only watch the password_changed, user_blocked and logout events.

API Endpoints

Call the Cloudflare Worker and get back some helpful information:

curl https://events.auth0a.com/sandrino-dev/_debug | jq

Call the Durable Object for my tenant and get back some helpful information:

curl https://events.auth0a.com/sandrino-dev/api/_debug | jq

Publish events to all listeners (used by Log Streaming)

curl https://events.auth0a.com/sandrino-dev/api/publish | jq

Note: This endpoint should require authentication in the future.

Connect to the stream to receive events:

curl https://events.auth0a.com/sandrino-dev/api/subscribe | jq

Note: After connecting you'll need to send a { "type": "authenticate", "access_token": "..." } message to be authenticated. Only then will you receive events (example).

Get a list of all listeners currently connected to the stream:

curl https://events.auth0a.com/sandrino-dev/api/listeners | jq

Note: This endpoint should require authentication in the future.

Get the last 100 events which have been published:

curl https://events.auth0a.com/sandrino-dev/api/events | jq

Note: This endpoint should require authentication in the future.
