Common errors with pubstack.io lines
-
DIRECT but intermediary
30 lines
If a partner holds this account and resells your inventory, the line should say RESELLER. If the account is yours, ask pubstack.io to list it as PUBLISHER.
-
RESELLER but publisher
5 lines
If the account is yours, declare it DIRECT. If a partner holds it, ask pubstack.io why the account is listed as PUBLISHER.
-
Seller ID not found
4 lines
Ask pubstack.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.
-
Seller type BOTH
4 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.
Intermediaries most declared as RESELLER
Accounts on pubstack.io that its sellers.json lists as INTERMEDIARY or BOTH, by the number of app-ads.txt files declaring them. Confidential sellers are left out.
