Adding a distributor
EFS integration requires that you specify a distributor for the individual products you will be supplying via eFulfillment Service. This way, when an order comes in, EFS products within the order will be flagged and sent to EFS for processing.
Log into your Shift4Shop Online Store Manager and, using the left navigation menu:
Go to Settings > General > Distributors.
Click +Add and name your "Distributor."
Adding your EFS Credentials to the Store
To add your EFS credentials to your store, log into your Shift4Shop Online Store Manager and, using the left navigation menu:
Go to Modules.
Search for the "eFulfillment Service" module and click on its + icon to expand the selection.
Then, click the Settings link.
Enter your EFS credentials, as well as the distributor* your store will use to designate EFS products.
Mark the "enable" checkbox and click Save at the top right to complete!
