Common errors with toponad.com lines
-
Seller ID not found
14,023 lines
Ask toponad.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
7,877 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
2,452 lines
If a partner holds this account and resells your inventory, the line should say RESELLER. If the account is yours, ask toponad.com to list it as PUBLISHER.
-
RESELLER but publisher
322 lines
If the account is yours, declare it DIRECT. If a partner holds it, ask toponad.com why the account is listed as PUBLISHER.

Questions about toponad.com
How do I add toponad.com to app-ads.txt?
Add one line for each account toponad.com gives you: "toponad.com, YOUR_ACCOUNT_ID, DIRECT, 1d49fe424a1a456d". Use DIRECT when you hold the account yourself and RESELLER when a partner holds it and sells your inventory through toponad.com. The account ID must be the seller_id toponad.com lists for you in its sellers.json; toponad.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 toponad.com publish a sellers.json?
Yes. Its file at https://toponad.com/sellers.json listed 2,930 sellers when we last read it on 9 October 2026: 2,656 publishers, 270 intermediaries and 4 listed as both; 0% are confidential.
How many apps declare toponad.com in app-ads.txt?
118,312 apps in Stoqlab's data (delisted apps included) declare toponad.com: 45,592 with at least one DIRECT line and 114,629 with at least one RESELLER line, across 16,259 app-ads.txt files. Counts are recomputed daily.
What is the certification authority ID for toponad.com?
100% of the app-ads.txt lines naming toponad.com carry "1d49fe424a1a456d" 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 toponad.com lines fail verification?
Of 109,280 lines naming toponad.com, 16,797 contradict its sellers.json. The most common case is "Seller ID not found" (14,023 lines): Ask toponad.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.
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.
