## Path parameters

## Response `200`

Success

- object
  - `success` true, required
  - `data` ProjectsInviteProjectMemberResult, required
    - `id` string, uuid, required
    - `project_id` string, uuid, required
    - `email` string, email, required
    - `status` 'preparing' | 'pending' | 'accepted' | 'expired' | 'revoked' | 'unknown' | 'failed', required
    - `delivery` 'accepted' | 'unknown' | 'rejected', required
    - `expires_at` string, nullable, required

## Other responses

- `400`: Invalid request parameters
- `401`: Invalid or missing API key
- `403`: Authenticated caller lacks permission for the operation
- `404`: Resource not found
- `409`: The request conflicts with the current state of the resource
- `429`: Rate limit exceeded. The `ratelimit-*` headers describe the limiter that rejected this request, with its own limit and window, not the API budget that successful responses report. A limiter that reports only a wait sends `Retry-After` alone.
- `502`: invitation_unconfirmed: the identity provider did not confirm the invitation's state. Nothing was changed locally that could send a second invitation; retry the same request to refresh it.
- `503`: directory_limit: the organization agent directory is larger than projects can read. Narrow the directory before retrying.
