Slack
Salesforce-owned team chat platform with a deep app ecosystem — the most common destination for automation notifications.
Definition
Slack is the default team chat tool for most software companies and a top webhook destination in automation platforms. It exposes a rich Web API, an Events API for subscriptions, and slash commands for triggering workflows. Most n8n, Make, and Zapier scenarios end with a Slack message to a channel or a DM to an operator.
