Common errors with anzu.io lines
-
Seller type BOTH
728 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
542 lines
If the account is yours, declare it DIRECT. If a partner holds it, ask anzu.io why the account is listed as PUBLISHER.
-
Seller ID not found
201 lines
Ask anzu.io 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.
Intermediaries most declared as RESELLER
