Common errors with tredio.io lines
-
Seller type BOTH
260 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
193 lines
If the account is yours, declare it DIRECT. If a partner holds it, ask tredio.io why the account is listed as PUBLISHER.
-
Seller ID not found
164 lines
Ask tredio.io 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.
-
DIRECT but intermediary
106 lines
If a partner holds this account and resells your inventory, the line should say RESELLER. If the account is yours, ask tredio.io to list it as PUBLISHER.

Questions about tredio.io
How do I add tredio.io to app-ads.txt?
Add one line for each account tredio.io gives you: "tredio.io, YOUR_ACCOUNT_ID, DIRECT". Use DIRECT when you hold the account yourself and RESELLER when a partner holds it and sells your inventory through tredio.io. The account ID must be the seller_id tredio.io lists for you in its sellers.json; tredio.io 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 tredio.io publish a sellers.json?
Yes. Its file at https://tredio.io/sellers.json listed 55 sellers when we last read it on 9 October 2026: 32 publishers, 21 intermediaries and 2 listed as both; 0% are confidential.
How many apps declare tredio.io in app-ads.txt?
93,808 apps in Stoqlab's data (delisted apps included) declare tredio.io: 9,493 with at least one DIRECT line and 93,779 with at least one RESELLER line, across 11,796 app-ads.txt files. Counts are recomputed daily.
Why do tredio.io lines fail verification?
Of 28,077 lines naming tredio.io, 463 contradict its sellers.json. The most common case is "RESELLER but publisher" (193 lines): If the account is yours, declare it DIRECT. If a partner holds it, ask tredio.io why the account is listed 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.
