Schedule by Zapier + Slack + Rendex

Send daily Slack channel messages with Rendex screenshots of logged-in pages

Set up this Zap to effortlessly review a page that lives behind a login -- a dashboard, an account view, an internal report -- without manually opening it yourself. This captures the authenticated page with Rendex using your saved session and posts the image to Slack on your schedule.
