Common errors with triplelift.com lines
-
Seller ID not found
66,958 lines
Ask TripleLift 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.
-
RESELLER but publisher
56,802 lines
If the account is yours, declare it DIRECT. If a partner holds it, ask TripleLift why the account is listed as PUBLISHER.
-
Seller type BOTH
28,690 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
12,263 lines
If a partner holds this account and resells your inventory, the line should say RESELLER. If the account is yours, ask TripleLift to list it as PUBLISHER.
