Common errors with kargo.com lines
-
Seller type BOTH
5,412 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
278 lines
If a partner holds this account and resells your inventory, the line should say RESELLER. If the account is yours, ask Kargo to list it as PUBLISHER.
-
Seller ID not found
262 lines
Ask Kargo 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
146 lines
If the account is yours, declare it DIRECT. If a partner holds it, ask Kargo why the account is listed as PUBLISHER.
