What are Private Extensions?
These are extensions that you create for one or more merchants, but not for the masses. Your extension is not published on the marketplace.
Since private extension caters majorly to a specific seller having a distinct requirement, it need not be published. Moreover, it doesn't require Fynd's approval and it's as per the mutual contract between you and the seller.
