Fax status lookups return only your account's faxes
GET /api/v1/fax/{faxId}, OpenAPI, and MCP clients
- What changed
- A fax sent from the website without signing in has no owning account. Before, any live API key holding that fax's ID could read its status and destination number. Those lookups now return 404, the same as a fax owned by another account. A fax ID with no FaxDrop record (older than the 90-day record window, or never sent through FaxDrop) also returns 404 now; before, the route fetched its status straight from the carrier for any live key.
- Behavior impact
- Faxes sent with your API key or while signed in to your account return the same status, fields, and destination number as before. Only faxes your account did not send, and faxes older than 90 days, return 404. A 404 for a fax older than 90 days means the record expired, as the error hint already says.
- Action needed
- No action needed for faxes your integration sends. Treat a 404 as not found for this key; do not retry it.
