API keys are not accepted as a Bearer token. If your script or integration sends the key as Authorization: Bearer YOUR_API_KEY, the request will be rejected with a 401. Switch it to the X-API-Key header instead.

Example request

To check that your key works, call the /seat/me endpoint:

Copy code

curl https://api.sendr.io/seat/me \
  -H "X-API-Key: YOUR_API_KEY"

Common authentication errors

Status	Meaning
401 Unauthorized	API key is missing, invalid, revoked, or sent in the wrong header
403 Forbidden	Key is valid but does not have access to this resource

If you receive a 401, check that your key is sent in the X-API-Key header (not Authorization), that it was copied in full, and that it has not been revoked. See "Creating and revoking API keys" if you need to generate a new key.

For every endpoint and request format, see the full API reference at docs.sendr.io.
