# Bulk activate users

`POST /v3/users/activate/bulk`

## Request

- Base URL: `https://harvest.greenhouse.io`
- URL: `https://harvest.greenhouse.io/v3/users/activate/bulk`
- Auth: OAuth 2
  - Authorization code: `https://auth.greenhouse.io/authorize`
  - Client credentials
  - Token URL: `https://auth.greenhouse.io/token` scopes: `harvest:users:activate`

Reactivate up to the bulk-endpoint cap of users in a single request. Pass an array of user ids in `data`; each id is processed independently and the response reports per-row success or failure. Equivalent to calling `POST /v3/users/{id}/activate` for each id but submitted as one request — use for HRIS-driven onboarding waves where many users return to active status together.

## Request body

- object
  - `callback_url` string: Optional HTTPS URL Greenhouse will POST to when every row in `data` has finished. Omit to poll `GET /v3/bulk_requests/{bulk_action_uuid}` instead.

## Response `202`

Accepted

- object
  - `bulk_action_uuid` string: UUID assigned to the new bulk request. Use this with `GET /v3/bulk_requests/{bulk_action_uuid}` to monitor progress and retrieve per-row results.
  - `status` string: Initial lifecycle state of the new bulk request, typically `building` immediately after creation. See the bulk request response schema for the full set of values.
  - `status_url` string: Relative path that returns the current status of the bulk request. Append this to your Harvest base URL to fetch the latest state.

## Other responses

- `401`: Unauthorized
- `413`: Payload is larger than 10MB
- `422`: Validation Error
- `429`: Client has more than 5 active jobs
