Step 1 of 3

No login required

The magic link is the credential. Anyone with the link can review — no account needed.

Expires automatically

Each link has a configurable expiry. Once expired, the checkpoint closes and the workflow is notified.

Decision fires a webhook

When the reviewer clicks Approve or Reject, Relayna immediately POSTs the result to your callback URL.
