# Revert a bracket node result

`POST /tournaments/{identifier}/nodes/{nodeId}/revert-result`

## Request

- Base URL: `https://teambattles.gg/api/v1`
- URL: `https://teambattles.gg/api/v1/tournaments/{identifier}/nodes/{nodeId}/revert-result`
- Auth: HTTP bearer

Reverts an applied result on a COMPLETED or WALKOVER node and rolls the bracket back to it, cancelling the unplayed downstream matches the result created. The cascade policy is SHALLOW: answers 409 error_revert_blocked_downstream if any node the result fed has already been played, so revert a chain from its tip inwards. Answers 400 error_invalid_input when the tournament is not IN_PROGRESS, when the node has no applied result, or when a later swiss round has already been paired. `regenerateMatch` defaults to true. Requires the tournaments bracket capability and ADMIN authority - a tournament MODERATOR answers 403.

## Path parameters

- `identifier` string, required: Tournament slug.
- `nodeId` string, required: Bracket node ID.

## Request body

- TournamentRevertNodeResultBody: Bracket node result revert payload.
  - `regenerateMatch` boolean: Whether to generate a fresh match for the reverted node. Defaults to true when omitted.

## Response `200`

The result was reverted.

- TournamentWriteAck: Acknowledgement returned by the tournament write endpoints whose backing operation has nothing to return - the organizer writes (endpoints 22-34), the team roster writes (40, 41), and the competitor self actions that neither mint nor resolve a row (38, 39, 44, 45, 47). Endpoints that mint a row answer with that row's id instead, and the two respond endpoints (42, 46) answer with the decision they recorded.
  - `success` true, required: Always true; failures are error responses.
  - `timestamp` string, required: Response generation time (ISO 8601).
