# Close tournament registration

`POST /tournaments/{identifier}/registration/close`

## Request

- Base URL: `https://teambattles.gg/api/v1`
- URL: `https://teambattles.gg/api/v1/tournaments/{identifier}/registration/close`
- Auth: HTTP bearer

Moves a REGISTRATION_OPEN tournament to REGISTRATION_CLOSED. Takes no request body. Any other status answers 400. This is REVERSIBLE - registration can be re-opened from REGISTRATION_CLOSED. Unlike opening, closing emits NO webhook and does not change the tournament's public listing, so a webhook consumer will not observe this transition; poll the tournament if you need to react to it. Requires an API key holding the tournaments lifecycle capability whose owner is a tournament ADMIN - a tournamentStaff MODERATOR is NOT sufficient and receives 403.

## Path parameters

- `identifier` string, required: Tournament slug.

## Response `200`

Registration is closed.

- TournamentCloseRegistrationResponse: Result of closing tournament registration.
  - `success` true, required
  - `status` 'REGISTRATION_CLOSED', required: The lifecycle status this call set.
  - `timestamp` string, required

## Other responses

- `400`: Bad request (invalid body, cursor, limit, or date).
- `401`: Missing or invalid API key.
- `403`: API key lacks the required permission.
- `404`: Resource not found.
- `429`: Rate limited.
- `500`: Internal server error.
