# Mint Campaign Test Join Link

`POST /v1/interviews/{interview_id}/join-link/test`

Mint a signed, short-lived TEST join link for the author's dry run.

Registrations through it create invisible test-lab contacts (excluded
from participants, results, and sends), so the author can walk the exact
QR participant flow — including on a pre-launch draft — without touching
the real campaign. Stateless: nothing is stored, the token expires on
its own.
