Common errors with outbrain.com lines
-
Seller ID not found
85,308 lines
Ask outbrain.com 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.
-
Seller type BOTH
3,409 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.
-
RESELLER but publisher
73 lines
If the account is yours, declare it DIRECT. If a partner holds it, ask outbrain.com why the account is listed as PUBLISHER.
-
DIRECT but intermediary
63 lines
If a partner holds this account and resells your inventory, the line should say RESELLER. If the account is yours, ask outbrain.com to list it as PUBLISHER.

Questions about outbrain.com
How do I add outbrain.com to app-ads.txt?
Add one line for each account outbrain.com gives you: "outbrain.com, YOUR_ACCOUNT_ID, DIRECT". Use DIRECT when you hold the account yourself and RESELLER when a partner holds it and sells your inventory through outbrain.com. The account ID must be the seller_id outbrain.com lists for you in its sellers.json; outbrain.com 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 outbrain.com publish a sellers.json?
Yes. Its file at https://www.outbrain.com/sellers.json listed 2,915 sellers when we last read it on 9 October 2026: 2,778 publishers, 93 intermediaries and 44 listed as both; 0% are confidential.

Of 91,849 lines naming outbrain.com, 85,444 contradict its sellers.json.

Buyers that check sellers.json drop these paths.
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.
