Slack works by configuring webhooks that receive data. Every time the webhook is called, the data will be posted to a channel in your Slack.
Create a Slack incoming webhook #
In your Slack account, on the web interface, you can navigate to Apps and add an incoming webhook.
Once you're in the Apps section, create a new incoming webhook and set the default channel to where you'd like your notifications to be sent to.
You'll get a webhook URL in return, we'll use that to add the notifications in Oh Dear.
Add the webhook to Oh Dear! #
Now that you've created the webhook, copy/paste the URL in our notification settings. Next up, determine which events should be sent and you're done.
For more details, see the official Slack documentation on webhooks.
