# Cancel invitation

`DELETE /v1/invitations/{invitationId}`

## Request

- Base URL: `https://api.inth.com`
- URL: `https://api.inth.com/v1/invitations/{invitationId}`
- Auth: HTTP bearer

Cancels only a still-pending invitation. A concurrent acceptance or deletion returns 409. Requires members.write, a user token, and an admin or owner role.

## Path parameters

- `invitationId` string, required

## Response `200`

Invitation was cancelled.

- object
  - `success` true, required
  - `data` DeleteResult, required
    - `deleted` boolean, required

## Other responses

- `400`: The request payload or parameters are invalid.
- `401`: Authentication is missing, invalid, or expired.
- `403`: The credential is valid but may not perform the operation. `INSUFFICIENT_SCOPE`: the credential was never granted the capability the operation needs. `details.requiredScope` names it, and the `WWW-Authenticate` header carries `Bearer error="insufficient_scope"`. An OAuth client fixes this by requesting the scope; an organization API key cannot gain it. `FORBIDDEN`: the capability is present but the membership behind the credential lacks the role, or the resource belongs to another organization.
- `404`: The requested resource was not found.
- `409`: The request conflicts with the current resource state.
- `429`: The rate limit was exceeded. API key limits are set by plan tier (Starter 600/min, Pro 1500/min, Enterprise 3000/min). Check the Retry-After header before retrying.
- `500`: An unexpected internal error occurred.
