- Error Code 21916429:
ShortMessage: Integrated Merchant Credit Card is reset.
LongMessage: Merchant credit card has been removed as a payment method because you do not have an eBay gateway account. You may create one by going into My eBay, Payment Preferences.
This is only a warning, that would not prevent you from listing any new items or from updating any active listings and it is returned only to notify you, that this payment method has been removed because an eBay gateway account hasn't been created. In order to be able to accept credit card payments from buyers through the eBay checkout, you would need to have both an Internet merchant account and a payment gateway account and you can take a look at this link as a reference and you would be able to see some more information about payment gateway account and also for the current supported payment gateway providers.
