Proper App type for application syncing products with other platform

Shopify Apps
1

Hi there. I’m a working now on shopify PUBLIC app for https://picupmedia.com/ platform.

  • There are jewelery sellers on picupmedia platform, which have their inventory of jewelery products there.
  • Some of these jewelery sellers have also shopify store.
  • We want to release our app in 2 phases:
    1. Phase 1 - Jewelery sellers automatically upload their goods one way: FROM Picupmedia TO their Shopify store.
    2. Phase 2 - Jewelery sellers can sync their goods in both ways.

In documentation on shopify appstore requirements page i’ve found list of app types
and configuration requirements for them:

https://shopify.dev/apps/store/requirements#specific-requirements-for-certain-app-configurations

Questions:

  1. Which type of app should be chosen from the above configuration requirements?
  2. Should the app be listed or unlisted type ? (https://shopify.dev/apps/store/visibility#listed-apps)
    thanks in advance for your prompt reply.
