Common errors with 33across.com lines
-
Seller type BOTH
49,165 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
4,909 lines
If a partner holds this account and resells your inventory, the line should say RESELLER. If the account is yours, ask 33Across to list it as PUBLISHER.
-
RESELLER but publisher
1,246 lines
If the account is yours, declare it DIRECT. If a partner holds it, ask 33Across why the account is listed as PUBLISHER.
-
Seller ID not found
574 lines
Ask 33Across 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.

What is the certification authority ID for 33Across?
