This documentation is made for store platforms, where there is no web-service/API options. In this scenario, you can import your product list and then sync with URL information. This gets a bit manual if your product list grows on a daily basis
Steps to import your product list
Export your product list to an excel or csv file as shown in the sample
Login to your Plumb5 account and click on manage account to get to your configuration tab
Select Import Product. Give you list a name and import the exported file . Hit the “Configure button’ to finish.
