Missing or invalid reseller API key
Reseller v1 routes (/api/v1/reseller/…) returned 401 Missing or invalid reseller API key.
Why this happens
No key sent, wrong header format, revoked/rotated key, or typo. Distinct from No active reseller API key (member has none to use when generating/calling from account context).
Diagnose and fix
1. Send the current key as documented on Reseller API (header/scheme required by the product).
2. Regenerate under Reseller API key (member) if the old key was rotated.
3. Confirm the account still has reseller API access.
4. See Errors return JSON {errorJson} for how failures are encoded.
