ADVERTISER_ID_INVALID Invalid Advertiser ID

The `advertiser_id` in your API request doesn't match any active advertiser account, or it belongs to an account your app doesn't have access to.

What causes this error?

The advertiser_id in your API request doesn’t match any active advertiser account, or it belongs to an account your app doesn’t have access to.

How to fix it

1. Check the ID: Ensure it’s copied correctly from the TikTok Ads Manager dashboard (it’s a numeric string).
2. Verify access: Use the /advertiser/info/ endpoint to list all advertiser accounts your app token has access to.
3. Business Center: If managing multiple accounts via Business Center, ensure the advertiser is properly linked.
