🚀Create an Application

Guide to creating your first application

App Types

• Private Available to you and your sub accounts (if Agency tariff), moderation-free

• Public Available to all users of the platform after moderation

To integrate with the Marketplace, you need to implement a separate application service that communicates with both the POS system and the Marketplace.

This service must expose several endpoints that the Marketplace will interact with.
