Slack Notification Plugin (Commercial)

The slack notification plugin offers Enterprise users the ability to send execution notifications to a certain slack channel given a certain event. When one of the following conditions is met, a notification will be sent to slack, depending which you chose:

On Start: the job was started
On Success: the job completed successfully
On Failure: the job failed or was aborted
On Avg. Duration: the execution exceeded the average duration of the job
On Retryable Failure: the job failed but will be retried

Webhook Base URL

Now that is is on, choose "Add new Webhook to Workspace" and choose the channel you would like the notifications to be posted in. After it is created, you will see a URL that looks like this:
https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX.
Your base URL would look like this: https://hooks.slack.com/services

T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX. Anything after the services/ should be places in this box.
