Every line naming 33across.com is looked up in its sellers.json. What each status means

Common errors with 33across.com lines

  • Seller type BOTH 49,924 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 4,948 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 1,259 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 579 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.
