Common errors with flashb.id lines
-
RESELLER but publisher
5,027 lines
If the account is yours, declare it DIRECT. If a partner holds it, ask flashb.id why the account is listed as PUBLISHER.
-
Seller ID not found
1,878 lines
Ask flashb.id 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.
-
Seller type BOTH
56 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
8 lines
If a partner holds this account and resells your inventory, the line should say RESELLER. If the account is yours, ask flashb.id to list it as PUBLISHER.
