# Replace usage budgets

`PUT /v1/accounts/{accountId}/business-agent/budget`

The full desired set: budgets left out are removed, an empty list returns to unlimited. Pass `budget_id` to edit one in place. When a cap is hit the agent finishes its turn, stops answering and hands the thread to a human until the window rolls over.

## Path parameters

- `accountId` string, required

## Request body

- object
  - `budgets` BusinessAgentBudget[], required
    - `budget_id` string — Pass it back to edit an existing budget; omit to add one.
    - `unit_type` 'token' | 'ai_turn', required — Tokens count across the Business Manager, AI turns per conversation.
    - `time_window` 'one_day' | 'seven_days' | 'fourteen_days' | 'thirty_days', required — Rolling window in the WABA timezone.
    - `max_budget` integer, required

## Response `200`
