First, you'll need to set up a new incoming webhook in your team's Slack configuration. An incoming webhook is a method for Slack to receive incoming messages to be posted to your Slack team from external services.
Once the webhook is created, you can optionally customise the channel, name, and icon which the webhook uses whenever it posts a new message. Either way, however, you'll need to copy the Webhook URL at the very top.
Now you can add your slack webhook to the integrations' section:
integrations: slack: - url: https://hooks.slack.com/services/T6QR3FYN7/BC34VRP/7KRWJAtQWOxjxYgee - url: https://hooks.slack.com/services/FGDR3FD34/BC34VRP/7KRWDSFSD3xjxYgee channel: channel12
You can also go further and connect other popular Polyaxon integrations to your Slack team using Zapier.
