Support TikTok Spark Ads with Website Conversion + Pixel Optimization

We need support for creating TikTok Spark Ads from an existing authorized TikTok post, while also using Website Conversion optimization with a TikTok Pixel and optimization event.

Our required flow is:

Campaign └── Ad Group ├── Website Conversion objective ├── Pixel ID ├── Optimization event (e.g. SHOPPING / ON_WEB_ORDER) └── Spark Ad ├── platformPostId └── sparkAuthCode

Today, these capabilities are split across two endpoints:

POST /v1/ads/boost → supports Spark Ads via platformPostId + sparkAuthCode → does not forward promotedObject / pixel settings POST /v1/ads/create → supports Website Conversion + promotedObject.pixelId + customEventType → does not support existing TikTok posts or Spark authorization codes

Because of this, the exact combination we need is currently not possible.

Requested capability

Please support creating a TikTok Spark Ad with:

{ "goal": "conversions", "promotedObject": { "pixelId": "76552139", "customEventType": "ON_WEB_ORDER" }, "platformPostId": "7659772882", "sparkAuthCode": "..." }

Ideally this could be supported either by:

• forwarding promotedObject correctly through /v1/ads/boost, or

• allowing /v1/ads/create to accept platformPostId + sparkAuthCode as the Ad creative source.

This is a critical capability for our TikTok Ads automation workflow because most of our TikTok ad testing uses Spark Ads + conversion optimization, rather than uploaded native creatives.

We are already building our Meta Ads automation workflow on Zernio and would like to use the same infrastructure for TikTok if this capability is supported.

This is currently a blocker for us adopting Zernio for TikTok Ads automation at scale.
