# List TikTok Business Centers

`GET /v1/ads/business-centers`

Returns the TikTok Business Centers (BCs) the connected `tiktokads` account can read.
Each BC reports its advertiser count so callers can build agency-style pickers
without re-walking `/v1/ads/accounts` per BC.

TikTok-only. Solo advertisers (non-agency tokens) return an empty array.

## Query parameters

- `accountId` string, required

## Response `200`

Business centers

- object
  - `businessCenters` BusinessCenter[]
    - `bcId` string — Business Center ID
    - `name` string — Display name set by the BC owner
    - `advertiserCount` integer, nullable — Number of advertisers reachable under this BC for the calling token. `null` when the BC asset walk returned empty or failed (typical for agency apps without full BC asset read scope), distinct from `0`, which would imply the BC genuinely has no advertisers.

## Other responses

- `400` — Invalid request
- `401` — Unauthorized
- `404` — The account or requested resource was not found or is not accessible. An account ID may have been disconnected and removed. Read GET /v1/accounts for current account IDs.
- `409` — The account exists but is inactive or needs reconnection. Reconnect it, then read GET /v1/accounts for its current account ID before retrying. Code: ads_connection_required.
- `422` — TikTok Ads not connected
