To access your payment method mappings, navigate to Customization > List, Records, & Fields > Record Types > Magento Payment Method Mapping > List (or View Records) inside of your NetSuite account.
This mapping is used to map credit card payment types, Check/Money Orders in Magento to corresponding payment types in NetSuite. By default, the mapping list contains the Magento Ids, but the NetSuite Internal Ids are still required (since these differ for each NetSuite account). To get the internal ids necessary to populate the NetSuite Internal Id values, go to Setup > Accounting > Account Lists > Payment Method. Click here if Internal Ids are not displayed in your account.
Note: Only if your Celigo Magento Connector version is < 3.x , when mapping new entries or changing existing ones, please be sure to refresh integration caches when you are finished.
