1. Create a Slack room for your Preact alerts.
May I recommend the name "preact-alerts"
2. Click on the arrow next to the room name > Add a Service Integration > Incoming Webhooks > Add Incoming Webhook
3. Copy your API token from the confirmation page.
Bonus: Change the image that alerts come from by expanding the "integration settings" at the bottom of the confirmation page.
4. In Preact, go to the Slack integrations page and insert your API token, team name and default channel.
5. Designate "alert-worthy" events using workflows.
6. Never miss an opportunity to engage with your customers.
