Common errors with kargo.com lines
-
Seller type BOTH
3,882 lines
The account is listed as BOTH, so sellers.json alone cannot tell a buyer which relationship applies. Nothing to fix on your side; buyers usually look at the seller's domain.
-
DIRECT but intermediary
184 lines
If a partner holds this account and resells your inventory, the line should say RESELLER. If the account is yours, ask Kargo to list it as PUBLISHER.
-
Seller ID not found
179 lines
Ask Kargo for the account ID it lists for you in its sellers.json, correct the line, or remove it if you no longer work with them. Buyers that check sellers.json drop these paths.
-
RESELLER but publisher
99 lines
If the account is yours, declare it DIRECT. If a partner holds it, ask Kargo why the account is listed as PUBLISHER.

Questions about Kargo
How do I add Kargo to app-ads.txt?
Add one line for each account Kargo gives you: "kargo.com, YOUR_ACCOUNT_ID, DIRECT, 98ccdd9948ed08da". Use DIRECT when you hold the account yourself and RESELLER when a partner holds it and sells your inventory through kargo.com. The account ID must be the seller_id Kargo lists for you in its sellers.json; Kargo will give it to you. Put the file at the root of the domain named as your developer website in the App Store and Google Play listings.
Does Kargo publish a sellers.json?
Yes. Its file at https://www.kargo.com/sellers.json listed 395 sellers when we last read it on 9 October 2026: 323 publishers, 35 intermediaries and 37 listed as both; 0% are confidential.
How many apps declare Kargo in app-ads.txt?
42,125 apps in Stoqlab's data (delisted apps included) declare kargo.com: 3,859 with at least one DIRECT line and 40,133 with at least one RESELLER line, across 5,067 app-ads.txt files. Counts are recomputed daily.
What is the certification authority ID for Kargo?
60% of the app-ads.txt lines naming kargo.com carry "98ccdd9948ed08da" in the fourth field. The field is optional; the IAB Tech Lab ads.txt 1.1 specification says identifiers in sellers.json supersede it, so a missing or different value does not make a line invalid.
Why do kargo.com lines fail verification?
Of 5,926 lines naming kargo.com, 462 contradict its sellers.json. The most common case is "DIRECT but intermediary" (184 lines): If a partner holds this account and resells your inventory, the line should say RESELLER. If the account is yours, ask Kargo to list it as PUBLISHER.
What is the difference between DIRECT and RESELLER?
DIRECT means the publisher owns the account; RESELLER means an intermediary sells the inventory on the publisher's behalf. DIRECT lines should match a PUBLISHER entry in the network's sellers.json, RESELLER lines an INTERMEDIARY entry.
