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

Common errors with display.io lines

  • Seller type BOTH 36,391 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 7,180 lines

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

  • DIRECT but intermediary 208 lines

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

  • Seller ID not found 142 lines

    Ask display.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.
