GET /r/{token}
Public browser redirect for a Knobase tracked click.
Resolve a tracked offer click and send the browser to an allowlisted destination.
Authentication
None. This is a public browser URL returned as `link` from POST /v1/offers/decide. Hosts must not replace it with a merchant URL.
Behavior
- A valid token redirects (302) to the destination recorded for that offer.
- An invalid token does not redirect to an arbitrary URL.
- Some clicks may show a short browser integrity challenge before redirect. That form posts to /r/{token}/challenge and is not a publisher API.
- Do not parse, mint, or log raw tokens in application code beyond storing the returned link.
Failure outcomes
| Outcome | Meaning |
|---|---|
| 302 | Click accepted; browser continues to the destination |
| 400 | Invalid token or invalid destination |
