Integrating Error Notifications to Slack

Overview

App notifications will inform you about your application’s errors through a channel of your choice. In this example, we will create a Slack app and link it to an App Notification so that messages are posted to a Slack channel.

Pre-requisites:

Before starting the configuration, create an #app-errors channel to receive the error messages in Slack.

Creating a Slack App

To post messages from apps into Slack, a Slack App must be created with an Incoming Webhook. 

  1. Go to  https://api.slack.com/messaging/webhooks#getting_started and click on Create your Slack app and then choose to create it from scratch. A modal will show up prompting you to name your app and then pick the workspace you’ll be using. Then click on Create App.

We recommend pasting the URL in the channel’s topic since it will be needed later on to create the App Notifier in the Console.

Adding the App Notifier to your Org

In the Console, go to Settings > Notifications and click on Create new.
