UPDATE JAN 2: 

https://ecommerce.shopify.com/c/api-announcements/t/deadline-reminder-important-changes-to-productva...

UPDATE SEP 14 

Hey Devs!

We've recently shipped a new change to help with identifying calls that we consider deprecated.  We've added a new header to return on these calls:

X-Shopify-API-Deprecated-Reason

If you receive one of these headers in your response, this means Shopify considers that a deprecated call.  This is an effort to allow these calls to be machine readable, and loggable, in order to assist developers in identifying the areas that need to be updated.

Examples of calls that will return this header:

  • Creating a fulfillment without a location
  • Creating a product with variants that have "inventory_quantity"
  • Creating a new variant on a product that has "inventory_quantity"
  • Updating a variant with "inventory_quantity_adjustment"
  • Updating a variant with "inventory_quantity"

 

Happy Coding!

 

UPDATE JUNE 28: 

Hey Devs,

Just want to let you know that we are extending the deprecation deadline from July 1st to August 1st.  There will be a new post tomorrow with more details, but we just wanted to get it out there to maybe relieve some of the stress you are feeling headed into the weekend.

Most, if not all of your questions will be answered in the post tomorrow so try to save any queries for that!

Cheers All!

Ryan

 

Hey Devs,

Shopify is preparing to release multi-location inventory features to all merchants this summer. All apps that create fulfillments or manage inventory will need to be updated by July 1st, 2018, to remain functional on shops that track inventory across multiple locations.

Key dates

July 1st, 2018

  • Apps will no longer be able to create fulfillments without specifying a location
  • Apps will no longer be able to set inventory on the Product/Variant APIs

Migrating to support multi-location fulfillments

Shopify fulfillments are currently “location unaware”, meaning that when an app creates a fulfillment and fulfills an order, Shopify decrements the inventory with no concept of which location that inventory should be decremented from. In order to support merchants with inventory allocated across multiple locations, apps will need to include a location_id when creating fulfillments.

For details on how to migrate your apps to support multi-location, see our Multi-Location Fulfillment Migration Guide.

Migrating to support multi-location inventory

Currently inventory is set and adjusted on the product variant and is not tracked by any particular location. In anticipation of multi-location inventory, Shopify has released a new Inventory API, which includes two new endpoints: Inventory Item and Inventory Level. The Inventory API will allows apps to effectively manage inventory quantities across multiple locations.

For details on how to migrate your apps to support multi-location inventory, see our Multi-Location Inventory Migration Guide.

We’ll keep you up to date as we continue to make improvements to our platform’s multi-location fulfillment and inventory management capabilities, so you can continue to build the best apps to help extend these new features.

If you have any questions about this change, please read our detailed FAQ or contact deprecations@shopify.com.

 

Thanks,

Shopify Apps Team

Hey Ryan,

After 1st July, for a shop that does not enable multi-location inventory, will each variant of the shop linked to an inventory_item? Or inventory_item only present if a shop has multi-location inventory enabled?

EDIT:
It looks like all variants will have an inventory_item :) irregardless multi-location inventory is enabled or not.

Thanks a lot for all the help and insights you gave us so far. While performing our final acceptance tests, we found out that the `location_id` attribute of the order object is always set to `null` and instead, it is the fulfillement object which now holds the location from where the order is fulfilled. 

Will the `location_id` attribute of the order object be deprecated? 

Location_id on the order only exists if the order was made through a Shopify POS location.  These multi-location changes do not affect the Order API (this location_id was already there).

I just noticed that SKU will also need special handling, incurring even more calls. The Product Variant API guide doesn't have SKU marked as deprecated fwiw.

SKU will still be readable from the variant, but not writeable.  I'll look into a doc update for clarity.

After 1st July, for a shop that does not enable multi-location inventory, will each variant of the shop linked to an inventory_item? Or inventory_item only present if a shop has multi-location inventory enabled?

EDIT:

Inventory Items and Inventory Levels have been released and implemented since February.  All inventory logic has been using them since then, and yes they are useable without multi-location enabled.

Will the Liquid template variable variant.inventory_quantity be affected by this change?

Will the Liquid template variable variant.inventory_quantity be affected by this change?

There are no liquid updates planned for the initial release of multi-location.

Hi,

Will I be able to set the availability for multiple inventory_levels at once? The documentation seems to show that we'll only be able to set the availability of one inventory_level at one time.

If so, this will dramatically increase the amount of API calls we have to make. Previously, we were adjusting inventory at the Product-level (which only included the VariantID and InventoryQty) to help reduce the number of API calls we have to make.

Thanks

With the REST API, the only way to update multiple inventory levels in one call is by registering as a FulfillmentService and registering to be polled for inventory levels.

Using the new GraphQL Admin API however, you can easily update multiple inventory level in a single call (GraphQL doesn't use the concept of calls for rate limiting).  Example:

mutation {
  item1: inventoryAdjustQuantity (input: {inventoryLevelId: "gid://shopify/InventoryLevel/37685843?inventory_item_id=40011829139", availableDelta:3 }) {
    inventoryLevel {
      available
    }
    userErrors {
      field
      message
    }
  }
  
  item2: inventoryAdjustQuantity (input: {inventoryLevelId: "gid://shopify/InventoryLevel/37685843?inventory_item_id=40011857683", availableDelta:3 }) {
    inventoryLevel {
      available
    }
    userErrors {
      field
      message
    }
  }
  
  item3: inventoryAdjustQuantity (input: {inventoryLevelId: "gid://shopify/InventoryLevel/37685843?inventory_item_id=40011857875", availableDelta:3 }) {
    inventoryLevel {
      available
    }
    userErrors {
      field
      message
    }
  }
}

Hi,

1) What impact will it have on products for which inventory is not tracking?

2) How to fulfill orders with such products? We didn’t set up a FulfillmentService. It looks the only way, in this case, is fetch available locations and use one of them to set a location_id for the fulfillment?
Suppose we will set up a FulfillmentService soon, but if we are not on the schedule, need a way to create fulfillments.

1) What impact will it have on products for which inventory is not tracking?

The inventory item will still have a location_id but will have available = null

example from my store:

{
  "inventory_levels": [
     {
        "inventory_item_id": 871696400403,
        "location_id": 13968900152,
        "available": null,
        "updated_at": "2018-05-22T14:50:57-04:00"
     }
  ]
}

 

2) How to fulfill orders with such products? We didn’t set up a FulfillmentService. It looks the only way, in this case, is fetch available locations and use one of them to set a location_id for the fulfillment?

You can still create a fufillment without registering as a fulfillment service, and pass the required location_id parameter.
