Error reference / unauthenticated

Missing or invalid API key

The request carried no usable API key.

Problem type /problems/unauthenticated
HTTP status 401
Emitted by REST API (/v1)
Title values
Missing or invalid API key
Response headers WWW-Authenticate
Trigger
REST API (/v1): missing/unknown API key

What happened

The Authorization header was absent, was not of the form Bearer senv_live_... or Bearer senv_test_..., or named a key that is unknown, revoked, or expired. The response is HTTP 401 with WWW-Authenticate: Bearer.

What it means

Revoked, expired, and never-existed keys are reported identically. No request state is consulted before this check, so a 401 says nothing about the resource.

What to do next

Send the full key exactly as shown when it was created (it is shown once). If it was revoked, create a new one under Settings, API keys, or with POST /v1/keys using a key that still works.

Problem body

Every error is an RFC 9457 problem document with media type application/problem+json. The type member is the stable identifier to switch on; docs_url is this page.
