date |
yes | The day, YYYY-MM-DD. |
channel |
yes | Your channel name (lower case). To see these players, add a channels rule mapping their GA4 source to the same name. |
spend |
yes | Amount in currency (or the config’s currency). |
campaign |
Campaign id and name; defaults to the channel. | |
country |
Two-letter country code; empty means “not broken down”, so a country filter shows “–”. | |
impressions, clicks |
Counts, when you have them. | |
app |
One of the app’s keys; empty uses your only app. |
|
currency |
Three-letter code; defaults to the config’s currency. |
A one-off payment (a sponsorship) is one row on the day you paid, or split over the days it ran if you want daily cost per player to read right.
Players from these channels
Give the channel a trackable link so GA4 can credit its players: a Play Store link with a referrer (https://play.google.com/store/apps/details?id=com.example.game&referrer=utm_source%3Danna%26utm_medium%3Dinfluencer), then a rule:
"channels": [{ "medium": "influencer", "channel": "influencer" }]The App Store passes no referrer, so iOS players from such links land in Unknown.
Errors
| Message | Fix |
|---|---|
missing the column "date" |
The first row must name the columns. |
"1.11.2026" is not a day like 2026-01-31 |
Use ISO dates. |
