Common errors with mars.media lines
-
DIRECT but intermediary
2,137 lines
If a partner holds this account and resells your inventory, the line should say RESELLER. If the account is yours, ask mars.media to list it as PUBLISHER.
-
RESELLER but publisher
1,432 lines
If the account is yours, declare it DIRECT. If a partner holds it, ask mars.media why the account is listed as PUBLISHER.
-
Seller ID not found
63 lines
Ask mars.media 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
22 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.
