Arms a one-shot fuse on a virtual card. When the fuse is active, the next purchase on that card skips risk score validation and is automatically approved (subject to other checks). After that purchase fires, the fuse is consumed and risk validation resumes normally. Use this endpoint to temporarily unblock a trusted cardholder who is being incorrectly declined by the risk engine. Requires an API key with access level 2 or higher.
