# Update an action item

`PATCH https://evohub.io/api/v1/retro/boards/{boardID}/action-items/{itemID}`

Part of the [Retro API](https://docs.evohub.io/retro.md) reference · operationId `updateRetroActionItem`.

Changes an action item's status, due date or owner; send at least one.

- `status`: `open` or `done`. Marking an item done sets
  `completed_at`; reopening it clears it.
- `due_at`: RFC 3339, or `null` to clear it.
- `assignee_user_id`: a member of the organization, or `null` (or
  `""`) to clear it.

Fields left out are kept. The board must be active.

Requires the `retro:action:write` scope, and `retro:card:write` as
well.

## Authorization

Any one of:

- `bearerKey`
- `headerKey`

Where:

- `bearerKey`: HTTP Bearer — An EvoHub API key (`evohub_…`) as a bearer token.
- `headerKey`: API key in the header `X-API-Key` — An EvoHub API key (`evohub_…`).

## Path parameters

- `boardID` (string, required, example `brd_3f9a1c7e2b8d4a60`): The board's ID.
- `itemID` (string, required, example `act_5b2e8c1d9f4a7e30`): The action item's ID.
