# Complete/reopen activity

`POST /v2/activities/{id}/complete`

Mark an activity as completed, or reopen a previously completed one. Body is optional; `completed` defaults to `true`. Reopening (`completed: false`) a non-custom activity (created automatically from a stage template) that is no longer on the deal's current stage is rejected with `400` — the internal service would otherwise soft-delete it instead of reopening it. Completions made through this endpoint carry no user attribution (`completed_by` stays `null`). Requires the `ACTIVITIES_API` feature flag and an API key with the `activities:write` scope.

## Path parameters

- `id` string, uuid, required

## Headers

- `api-token` string, required

## Request body

- object
  - `completed` boolean — true to complete the activity, false to reopen it.

## Response `200`
