Seller type BOTH

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.

Ask decide.co 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.

Questions about decide.co
How do I add decide.co to app-ads.txt?
Add one line for each account decide.co gives you: "decide.co, YOUR_ACCOUNT_ID, DIRECT, 5e1158f8c4b38075". Use DIRECT when you hold the account yourself and RESELLER when a partner holds it and sells your inventory through decide.co. The account ID must be the seller_id decide.co lists for you in its sellers.json; decide.co 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 decide.co publish a sellers.json?
Yes. Its file at https://decide.co/sellers.json listed 493 sellers when we last read it on 9 October 2026: 478 publishers, 2 intermediaries and 13 listed as both; 0% are confidential.
How many apps declare decide.co in app-ads.txt?
105 apps in Stoqlab's data (delisted apps included) declare decide.co: 82 with at least one DIRECT line and 91 with at least one RESELLER line, across 58 app-ads.txt files. Counts are recomputed daily.
What is the certification authority ID for decide.co?
100% of the app-ads.txt lines naming decide.co carry "5e1158f8c4b38075" 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 decide.co lines fail verification?
Of 100 lines naming decide.co, 7 contradict its sellers.json. The most common case is "Seller ID not found" (7 lines): Ask decide.co 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.
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.
