ERROR: INVALID_KEY_OR_REF - Invalid paymentmethod reference key

This error is NetSuite telling FarApp that the payment method it is trying to use for the order is invalid. There are a few steps you can take to resolve this issue.

1. The reference key shown is the internal ID of the payment method. Look up the payment method in NetSuite using the internal ID.
   • Search payment methods in the global search bar in NetSuite and click on the Page: Payment Methods search result.
     
     
     
     
   • A list of payment methods will be displayed. If your NetSuite is configured to show Internal IDs you will see those as well. NOTE: If your NetSuite is not configured to Show Internal IDs you can enable that setting by following the steps in this article

2. Once you have located the payment method in question you can troubleshoot as to why NetSuite is not allowing the method to be used for the order by doing the following:
   
   • Edit and immediately save the payment method. If you have to enter additional information before NetSuite will let you save then provide the information and save, then try to sync the problem order again. If NetSuite did not require you to provide additional information before saving or you provided the information and saved but the order still fails then proceed to the next step.
   • If the previous step did not resolve the issue then try manually entering the order into NetSuite. Make sure you have the same subsidiary, customer, shipping address, items and payment method on the order. The expectation is that NetSuite will either not provide the payment method as an option for the order or will display an error when you try to save the order with that payment method. FarApp doesn't know why NetSuite isn't allowing the payment method to be used on the order. You will need to make the necessary adjustments in NetSuite and once you can enter the order manually using the payment method in question, FarApp should be able to send orders to NetSuite using that same payment method.
