Every line naming r2b2.io is looked up in its sellers.json. What each status means

Common errors with r2b2.io lines

  • Seller type BOTH 5 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.

  • Seller ID not found 3 lines

    Ask r2b2.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.

  • DIRECT but intermediary 1 line

    If a partner holds this account and resells your inventory, the line should say RESELLER. If the account is yours, ask r2b2.io to list it as PUBLISHER.
