# Unblock a flow

`POST /flows/{flowId}/unblock`

Clear a flow's blocked status after fixing the underlying issue. Idempotent — safe to call on already-healthy flows.

## Path parameters

- `flowId` string, uuid, required

## Response `200`

Flow unblocked (or already healthy)

- object
  - `data` Flow, required
    - `id` string, uuid, required
    - `userId` string, uuid, required — Deprecated: use ownerId (tenancy) / createdBy (actor).
    - `ownerId` string, uuid, required
    - `createdBy` string, uuid, nullable, required
    - `name` string, required
    - `description` string, nullable, required
    - `triggerId` string, uuid, required
    - `enabled` boolean, required
    - `deviceIds` string[], required
    - `cooldownSeconds` integer, nullable, required
    - `cooldownScope` 'flow' | 'device', required
    - `notifyWebhookId` string, uuid, nullable, required
    - `notifyOnSuccess` boolean, required
    - `notifyOnFailure` boolean, required
    - `lastTriggeredAt` string, nullable, required
    - `status` 'healthy' | 'failing' | 'blocked', required
    - `templateResolutionVersion` integer, required — Template-resolver semantics this flow runs under (MVA-23). 1 = legacy (missing/forbidden/null all resolve to ''). 2 = typed (missing/forbidden throw, a whole-token null stays JSON null). Existing flows stay 1; new flows default to 2.
    - `consecutiveFailures` integer, required
    - `lastFailureCode` 'device_not_found' | 'permission_denied' | 'client_error' | 'transient' | 'logic' | 'invalid_config', nullable, required
    - `lastFailureAt` string, nullable, required
    - `blockedAt` string, nullable, required
    - `createdAt` string, nullable, required
    - `updatedAt` string, nullable, required
