How can I update inventory quantity via API?

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.

Thank you for your help

I didn’t even understand what location was.

I could manage inventory.

I appreciate it again!
