Common errors with trustx.org lines
-
Seller ID not found
1,378 lines
Ask trustx.org 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
68 lines
If the account is yours, declare it DIRECT. If a partner holds it, ask trustx.org why the account is listed as PUBLISHER.
-
Seller type BOTH
2 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.
