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

Common errors with anzu.io lines

  • Seller type BOTH 734 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.

  • RESELLER but publisher 543 lines

    If the account is yours, declare it DIRECT. If a partner holds it, ask anzu.io why the account is listed as PUBLISHER.

  • Seller ID not found 202 lines

    Ask anzu.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.
