This API does not support Upgraded Smart Plus ads (TikTok Smart+)

What this error means

Smart+ is TikTok's automated buying (formerly Smart Performance Campaigns). TikTok does not allow those campaigns to be edited through its API, so any budget or status change from the chat, or from any other tool, comes back with this error.

Whose side it is on

TikTok's rule. Nothing is wrong with the account or the request.

How to fix it

1. Open the campaign in TikTok Ads Manager and change its budget or status there.
2. Do not retry in the chat; it will keep failing for that campaign.

Campaigns launched from AdWhispr are standard campaigns and can be changed normally.

Relaunch

Nothing to relaunch. Your standard campaigns keep working from the chat.

Frequently asked questions

Can I read a Smart+ campaign's performance?

Yes. Reads work; only changes are blocked.
