# LinkUnlocker

1. Open LinkUnlocker **User settings → Api Keys** and get the Redirect API token.
2. Enter it in the project's LinkUnlocker settings.
3. Add the LinkUnlocker links, add a package, enable the provider, and save.
4. Complete a test through the public flow page.

The token is used to prepare per-session encrypted redirects. The callback endpoint is `/api/integrations/linkunlocker/callback`. Vampauth provides the attempt-specific destination when preparing the redirect.

Don't use a Linkvertise anti-bypass token here. If the provider doesn't appear, inspect its readiness checklist rather than repeatedly adding the same link. If a callback is rejected, start/resume the real attempt in the original browser instead of pasting the callback manually.
