# Set mailbox established

`POST /api/v1/tools/set_mailbox_established`

## Request

- Base URL: `https://www.affiliatespy.io`
- URL: `https://www.affiliatespy.io/api/v1/tools/set_mailbox_established`
- Auth: HTTP bearer

Mark the project's mailbox established (true: no warm-up, the full daily cap applies at once) or not (false: the warm-up applies again). It belongs to the mailbox, so every project sending from it follows. Only for a mailbox with a sending history. Guarded: without approval_token it returns {error:"approval_required", approval_token, summary} for the user to confirm; call again with the token. Every dashboard guardrail still applies: this is exactly what a user clicking the dashboard could do, no more. GUARDED: requires the account's Unrestricted MCP setting; returns 403 {error:'restricted'} otherwise.

## Request body

- object
  - `app_id` string, uuid: Project id from list_apps. Omit to use your most recently added project.
  - `on` boolean, required
  - `approval_token` string: Approval token from a previous approval_required response, after the user said yes.

## Response `200`

The tool's JSON result (same payload the MCP tool returns).

- unknown

## Other responses

- `400`: Arguments failed validation; body lists the issues.
- `401`: Missing or invalid API key.
- `403`: Guarded tool with Unrestricted MCP off.
- `429`: Rate limited (60 requests per minute per key).
