Common errors with smaato.com lines
-
Seller ID not found
100,674 lines
Ask Smaato 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
26,643 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.
-
RESELLER but publisher
22,044 lines
If the account is yours, declare it DIRECT. If a partner holds it, ask Smaato why the account is listed as PUBLISHER.
-
DIRECT but intermediary
9,375 lines
If a partner holds this account and resells your inventory, the line should say RESELLER. If the account is yours, ask Smaato to list it as PUBLISHER.
