Slack - Instant Messaging

The slack sample template allows messaging to a slack channel or user. A slack app is required to use this template. The receiving slack workspace must download this app and authorize incoming webhooks. Slack provides a unique url for each channel/user to send a message. Copy and paste that url into the “API Endpoint” field in the template editor. Slack does not require authentication headers, so leave the auth fields blank.
