# Revoke a badge token

POST https://api.withwrit.com/v1/badge/tokens/revoke
Content-Type: application/json

API key required. Revokes one of the caller's badge tokens; its badge
image URL 404s from that moment on, so embeds show a broken image
rather than a stale claim. Only tokens belonging to the caller's
tenant can be revoked.
