Common errors with triplelift.com lines
-
Seller ID not found
49,101 lines
Ask TripleLift 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
41,250 lines
If the account is yours, declare it DIRECT. If a partner holds it, ask TripleLift why the account is listed as PUBLISHER.
-
Seller type BOTH
21,198 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
9,043 lines
If a partner holds this account and resells your inventory, the line should say RESELLER. If the account is yours, ask TripleLift to list it as PUBLISHER.
Intermediaries most declared as RESELLER

Questions about TripleLift
How do I add TripleLift to app-ads.txt?
Add one line for each account TripleLift gives you: "triplelift.com, YOUR_ACCOUNT_ID, DIRECT, 6c33edb13117fd86". Use DIRECT when you hold the account yourself and RESELLER when a partner holds it and sells your inventory through triplelift.com. The account ID must be the seller_id TripleLift lists for you in its sellers.json; TripleLift 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 TripleLift publish a sellers.json?
Yes. Its file at https://cdn.3lift.com/sellers.json listed 7,961 sellers when we last read it on 9 October 2026: 3,817 publishers, 4,068 intermediaries and 76 listed as both; 0% are confidential.
How many apps declare TripleLift in app-ads.txt?
144,774 apps in Stoqlab's data (delisted apps included) declare triplelift.com: 44,788 with at least one DIRECT line and 142,475 with at least one RESELLER line, across 21,452 app-ads.txt files. Counts are recomputed daily.
What is the certification authority ID for TripleLift?
97% of the app-ads.txt lines naming triplelift.com carry "6c33edb13117fd86" 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 triplelift.com lines fail verification?
Of 514,374 lines naming triplelift.com, 99,394 contradict its sellers.json. The most common case is "Seller ID not found" (49,101 lines): Ask TripleLift 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.
