Common errors with onetag.com lines
-
Seller ID not found
177,309 lines
Ask OneTag 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
29,340 lines
If a partner holds this account and resells your inventory, the line should say RESELLER. If the account is yours, ask OneTag to list it as PUBLISHER.
-
RESELLER but publisher
7,631 lines
If the account is yours, declare it DIRECT. If a partner holds it, ask OneTag why the account is listed as PUBLISHER.
-
Seller type BOTH
5,215 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
