With the Pull option, you can:
Upload items from GoldFinch to Shopify.
You can also choose to set up Shopify items directly in Shopify without using the upload routine.
Manually download or initialize a routine to automatically download Shopify orders into GoldFinch.
Upload the fulfillment status back to Shopify from Salesforce.
This option does not require a separate Salesforce API user license. All inbound and outbound transactions will be processed by the log-in user.
