The Zapier template allows sending content to zapier, which connects apps and automates workflows. A Zapier account is required to use this template. Zapier provides a unique url for each channel/user to send a message to. Copy and paste that url into the “API Endpoint” field in the template editor. Zapier does not require authentication headers, so leave the auth fields blank.
