Custom Data Feeds per Customer

in Development
We provide our customers a custom data feed, including their discounted pricing. I would like to use these custom feeds to update individual Lightspeed customer accounts so they have accurate inventory / pricing information.
Is this possible? Do I have to do a separate integration for each customer that uses Lightspeed? If so, is there an easy way to get the customer on-boarded with the data feeds, etc so humans don't have to be involved?
