# Update Rows

`PUT /api/v1/tables/{tableId}/rows`

Bulk update rows matching a filter. All matching rows will have the specified fields updated. Validates against schema and unique constraints.

## Path parameters

- `tableId` string, required

## Request body

- object
  - `workspaceId` string, required — The workspace that owns the table.
  - `filter` object, required — Filter criteria to match rows.
  - `data` object, required — Fields to update on matching rows.
  - `limit` integer — Maximum number of rows to update.

## Response `200`

Rows updated.

- object
  - `success` boolean — Indicates whether the request was successful.
  - `data` object — Response payload.
    - `message` string — Confirmation message describing how many rows were updated.
    - `updatedCount` integer — Number of rows that were updated.
    - `updatedRowIds` string[] — Array of IDs for each row that was updated.

## Other responses

- `400` — Invalid request parameters. Check the details array for specific validation errors.
- `401` — Invalid or missing API key. Ensure the X-API-Key header is set with a valid key.
- `403` — Access denied. You do not have permission to access this resource. For audit log endpoints, this requires an Enterprise subscription and organization admin/owner role.
- `404` — The requested resource was not found. Verify the ID is correct and belongs to your workspace.
- `429` — Rate limit exceeded. Wait for the duration specified in the Retry-After header before retrying. The X-RateLimit-* headers accompany every response from an authenticated v1 request — success and error alike — and are omitted only when the request fails authentication, since no rate-limit bucket is consulted in that case.
