# Ad spend

> Import spend from Meta or TikTok to see CPI and ROAS per campaign.

TrueOrigin puts spend next to installs and revenue by the ad network's **Campaign ID**.
That id reaches TrueOrigin through the `campaign_id` URL parameter, so set up the ad's
[URL parameters](/tracking-links) first.

For now spend comes in as a CSV export. In the dashboard: **Settings → Ad spend → Import
CSV → Choose CSV**. Export campaigns by day, with their Campaign ID.

## Meta

In Ads Manager, **Campaigns** tab:

1. **Breakdown → By time → Day**.
2. **Columns → Customize columns**: add **Campaign ID** and **Currency**.
3. Export the table as CSV.

Only campaign-level exports work; ad set and ad exports are rejected. A single-day export
without the Day breakdown works too.

## TikTok

TikTok's Campaigns table has no day breakdown and may export only Excel, so use a custom
report: **Analytics → Custom reports**, with the dimensions **Campaign ID** and **By Day**
and the metric **Spend**, exported as CSV. TikTok adds the Currency column by itself.

## File format

* CSV only, up to 10 MB. Excel (`.xlsx`) files are rejected: export as CSV.
* English or German column names, as your Ads Manager language exports them.
* Comma, semicolon or tab separated; UTF-8, UTF-16 or Windows-1252.
* Dates as `2026-09-15`, `2026/09/15` or `15.09.2026`. US dates like `9/15/2026` are refused
  because they are ambiguous.
* Importing a period again replaces the days already imported. Import every week or so to
  keep CPI and ROAS current.

If a file is refused, the message says which column is missing and how to add it.
