Common errors with cortextech.it lines
-
Seller ID not found
208 lines
Ask cortextech.it 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 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
1 line
If a partner holds this account and resells your inventory, the line should say RESELLER. If the account is yours, ask cortextech.it to list it as PUBLISHER.

Questions about cortextech.it
How do I add cortextech.it to app-ads.txt?
Add one line for each account cortextech.it gives you: "cortextech.it, YOUR_ACCOUNT_ID, DIRECT". Use DIRECT when you hold the account yourself and RESELLER when a partner holds it and sells your inventory through cortextech.it. The account ID must be the seller_id cortextech.it lists for you in its sellers.json; cortextech.it 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 cortextech.it publish a sellers.json?
Yes. Its file at https://cortextech.it/sellers.json listed 48 sellers when we last read it on 10 October 2026: 16 publishers, 11 intermediaries and 21 listed as both; 0% are confidential.
How many apps declare cortextech.it in app-ads.txt?
1,404 apps in Stoqlab's data (delisted apps included) declare cortextech.it: 399 with at least one DIRECT line and 1,141 with at least one RESELLER line, across 204 app-ads.txt files. Counts are recomputed daily.
Why do cortextech.it lines fail verification?
Of 222 lines naming cortextech.it, 209 contradict its sellers.json. The most common case is "Seller ID not found" (208 lines): Ask cortextech.it 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.
