Using Octopus Subscriptions

Mark Siedle's blog post introduces the Octopus Subscriptions feature by demonstrating how to set up notifications to a Slack channel whenever critical events occur in Octopus, using Zapier to facilitate the process. The example walks through setting up a Zapier webhook to catch events from Octopus and trigger Slack notifications. The process involves creating a Zap in Zapier with a "Catch Hook" trigger to receive a webhook URL, which is then used to configure a subscription in Octopus. This subscription is set up to notify the Slack channel about specific critical events, such as deployment failures, by filtering them with an Event Group filter. The integration allows for real-time updates in the Slack channel "critical-stuff," enhancing team communication regarding important events in Octopus.
