What it does

Listens for Dropbox sharing events in real time. When a folder gains a new member, it checks the member's email domain against your allowlist of corporate and approved-partner domains. Any share to an outside address is treated as a potential data-exfiltration risk and triggers an immediate alert with the folder name, the external recipient, and the access level granted.

When to use it

Use this when external sharing must be tightly controlled and you cannot wait for a daily report to catch a folder being opened to a personal Gmail or an unvetted vendor. It turns Dropbox's own event stream into a live guardrail.

How it works

  1. 1A Dropbox sharing webhook fires the moment a member is added to any folder.
  2. 2The flow pulls the new member's email and the affected folder's details.
  3. 3A logic branch compares the recipient domain to the approved-domain allowlist.
  4. 4Internal shares are recorded silently and the run ends.
  5. 5External shares trigger an urgent Slack alert to the on-call channel with full context for immediate review or revocation.
