How can I update inventory quantity via API?

Retired Boards Appdev Graphql Basics And Troubleshooting

Topic summary

Goal: change a product’s inventory quantity via API using the Shopify Python SDK.

Key guidance provided:

  • Use the Shopify Admin API inventory resources (docs linked). Inventory is tracked on InventoryItem and InventoryLevel, tied to a Location per product variant.
  • Workflow suggested: after creating/saving the product and variants, get variant.inventory_item_id and call InventoryLevel.set with inventory_item_id and location_id to set the quantity for that location. The responder wasn’t certain about Python SDK specifics but pointed to the REST docs and examples.

Notable clarifications:

  • “Location” refers to the fulfillment/stock location; understanding this enabled the original poster to manage inventory successfully.

Code context:

  • A Python snippet showed product creation; the inventory snippet was partial. The linked docs are central for implementation details.

Current status:

  • The original poster confirmed they solved it but did not share code.
  • Follow-up questions asking how they achieved it, whether any libraries are required, and where to write the code remain unanswered. The thread is partially unresolved.

I would like to change inventory quantity of products, but I don’t even know how to do that.

Here is a part of example to list a product I try to do.

product = shopify.Product()
product.title = "example"
product.save()

The SDK should be similar to Shopify Admin API, so check the API docs on inventory handling:

https://shopify.dev/api/admin/rest/reference/inventory

https://shopify.dev/api/examples/product-inventory

Inventory is now tracked against InventoryItem and InventoryLevel in connection to a Location on each product variant.

I’m not familiar with the Python SDK, not sure if InventoryItem will be auto-populated on the Variant object, but I’m guessing after saving the product, you can do something like:

inv = shopify.InventoryLevel()
inv.set(inventory_item_id=variant.inventory_item_id, location_id=

Should return a collection, then call set() method to set the inventory for a location.
