Connecting API to custom warehouse

Hello!

We wish to implement order export into our system and additionally - Import/export of stock into Shopify and into our warehouse.

We tried using these as information :

https://shopify.dev/docs/api/admin-rest/2023-07/resources/inventorylevel

https://shopify.dev/docs/api/admin-rest/2023-07/resources/order#get-orders?status=any

But our developer said that it only allows us to import information into our warehouse, not export to Shopify.

We just need it to be possible to manage the quantities of products, so if a person were to buy something through a physical store, the quantity would be updated into the warehouse and then also in our e-store.

Kind regards,

Leo Saudens
