Common errors with soundcast.io lines

  • Seller type BOTH 1,291 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 1,124 lines

    Ask soundcast.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.

  • RESELLER but publisher 354 lines

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

  • DIRECT but intermediary 2 lines

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