Common errors with adform.com lines
-
Seller type BOTH
101,124 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.
-
Seller ID not found
12,434 lines
Ask Adform 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
2,091 lines
If a partner holds this account and resells your inventory, the line should say RESELLER. If the account is yours, ask Adform to list it as PUBLISHER.
-
RESELLER but publisher
840 lines
If the account is yours, declare it DIRECT. If a partner holds it, ask Adform why the account is listed as PUBLISHER.
-
Confidential seller
98 lines
The seller is confidential in sellers.json: its name and domain are hidden, so buyers cannot confirm who it is.
