Connecting API to custom warehouse

Retired Boards Appdev Authentication

Topic summary

A user is attempting to set up bidirectional inventory synchronization between Shopify and their custom warehouse system, along with order export functionality.

Current Implementation Goal:

  • Export orders from Shopify to their warehouse
  • Two-way inventory sync: updates from both Shopify store and physical warehouse should reflect in both systems
  • Example use case: Physical store purchase should update inventory in both warehouse and Shopify

Technical Resources Referenced:

  • Shopify Admin REST API documentation for Inventory Level
  • Shopify Admin REST API documentation for Orders

Issue Identified:
Their developer reports the current API setup only allows importing data into the warehouse from Shopify, but does not support exporting inventory updates back to Shopify.

Status: The discussion remains open with no solution provided yet. The core challenge is achieving bidirectional inventory synchronization rather than one-way data flow.

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
