The Notifications service allows you to choose the events of interest to you and decide where to send corresponding notifications.


Historically and by default, deployment result e-mails (deployment succeeded or failed) were always sent to the owners of an application, namely the user themselves or the organization’s members.

To disable the deployment result e-mails or restrict it to only some applications:

  1. Go in Organization Manager > Notifications panel.
  2. Delete the hook named Default deployment result e-mails.
  3. Add a new one.
  4. Set it to your liking.

In the future, this service will also handle credits warning notifications and others to come. You will be able to choose wether or not to receive an e-mail and/or for these events to be forwarded to a web service via a webhook.


From Wikipedia:

A webhook in web development is a method of augmenting or altering the behavior of a web page, or web application, with custom callbacks. These callbacks may be maintained, modified, and managed by third-party users and developers who may not necessarily be affiliated with the originating website or application.

In practical terms, this means that you can choose to receive all deployment result events on an endpoint of your application without having to listen to all events via the Websocket API. No more lost events and having to reconnect to the websocket if and when it fails.

To create a webhook stay on the Notifications panel:

  1. Click on Webhooks button at the top of the Notifications window.
  2. Add a new one.
  3. Choose the URL which will receive the data through a POST request and the format it will be sent as.

As of now, you can choose between 3 formats: raw, slack and flowdock. The raw format is the Clever Cloud internal representation of events, it is identical to events sent by the Websocket API. Slack and Flowdock formats are to be used with the corresponding services: Slack and Flowdock.

You can also choose which events you want and restrict notifications to a list of applications and addons.

Example: Slack deployment results Webhook

First, you will have to create the Incoming WebHooks integration on Slack:

Let’s go to the custom integrations page, once there go to Incoming WebHooks.

You will find an Add Configuration button on the left which will take you to the page where you need to configure the integration. You just need to select the channel where you want the notifications to be posted, then it will show you the Webhook URL, it starts with Copy that URL.

Now, let’s create the Webhook!

You should already have a tab opened on the Webhook creation page; if it’s not the case, follow the Webhooks section above.

There, you just need to paste the URL you copied before in the Webhook URL field, then select Result of deployments (success/fail) in the Only send notification for these events menu.

You can now push your application or restart it and you will see the result of the deployment in your Slack channel.
