Add placement breakdown to TikTok ad performance data

What we need

Performance metrics (impressions, spend, conversions) broken down by placement for TikTok ad accounts, available through the insights

endpoint in the same way other breakdowns are returned.

Why we believe TikTok provides this

We verified it in TikTok Ads Manager. Under Analytics > Custom reports > Create report, the Dimensions panel has a Targeting group containing Placement. Selecting Placement together with impressions and spend returns rows normally.

Measured on ad account 7450327792480518161 for September 2026, the Placement column returns surface-level values, not app names:

- TikTok

- TikTok Ad Network

- News Feed App Series

The same Targeting group also exposes Platform, Device, Gender, Age, Country/Region, Sub-region, DMA, Language, Interest, Behavior and Connection type. We are raising those separately; this request is only about Placement.

What we get today

When we request breakdowns for a TikTok account, the API returns HTTP 200 but the response contains no breakdowns key at all. Because of this we cannot distinguish "not supported" from "no data for this period".

A clear error for unsupported dimensions would also help us.

Why this matters to us

Without placement data, advertisers cannot see where their budget is actually being delivered. On the account above, September 2026, purchase campaigns only:

Placement Spend share Conversion share CPA

TikTok 69.5% 94.7% 2,012 KRW

TikTok Ad Network 30.2% 5.2% 15,782 KRW

News Feed App Series 0.3% 0.1% 11,349 KRW

TikTok Ad Network consumed 30% of spend and returned 5% of conversions.

This held across all 7 purchase campaigns, with CPA 2.6x to 27.7x worse than the main TikTok feed in every one of them.

In our reporting these placements are merged into a single number, so a campaign whose real in-feed CPA is 1,130 KRW is shown to the advertiser as 2,882 KRW with no way to see the cause. The advertiser ends up blaming the creative when the issue is where the budget was delivered.

One caution on our side: conversion counts differ by campaign objective, so traffic campaigns must not be mixed with purchase campaigns when comparing. We handle that ourselves, but mention it in case it affects how the data is aggregated.

What we are asking for

Placement as a breakdown dimension on TikTok performance data, returning the placement values exactly as TikTok labels them.
