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

Common errors with vrtcal.com lines

  • RESELLER but publisher 932 lines

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

  • Seller ID not found 86 lines

    Ask vrtcal.com 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.

  • Seller type BOTH 15 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.
