Error codes
Every code from the Problem body
(RFC 9457)
with its own anchor — the type field of every error response points
here (the raw specification always uses the German page; this English page is for
readers of this guide). The full table with status codes is also on the
overview page.
400 bad_request
A dependency rejected the request without its own code; the status follows that dependency.
401 unauthorized
Key missing, unknown, malformed, expired, revoked, or the caller's IP is not allowed — one code for every reason.
403 insufficient_scope
A required scope is missing; detail names it.
403 privacy_restricted
The team has turned off per-person detail (member_detail_enabled).
403 api_disabled
Tenant suspended or ended.
403 vorgabe_gesperrt
A policy assigned to the recipient blocks this situation, personality or industry (assignments only).
404 not_found
Either never existed, or belongs to a different tenant — indistinguishable from the outside.
409 conflict
The email already belongs to a team member or the team's owner, or a concurrent call with the same Idempotency-Key is still in progress.
409 seat_limit_reached
All of the team's seats are taken.
409 last_admin
The member is the team's only active admin; changing their role or removing them would leave the team without one.
409 owner
The team's owner cannot be removed or have their role changed through this API.
422 validation_error
A query, path or body value failed validation. A form error detected while parsing the request carries errors (a list); a business-rule error the application checks instead carries field (a single field name).
422 idempotency_mismatch
The Idempotency-Key header was reused with a different request body.
422 kombination_ungueltig
The situation, personality or industry id is unknown, not visible to this team, or violates a catalog rule (assignments only).
429 rate_limited
Limit reached; Retry-After names the number of seconds to wait.
500 internal
Unexpected error; the body deliberately reveals no internals — request_id helps when contacting support.
