When will CreateSupplier and PurchaseOrderCreateMutation be available to use?

Topic summary

Developers are requesting API access to programmatically create purchase orders (POs) in Shopify, noting that while the feature exists in the admin interface, the corresponding CreateSupplier and PurchaseOrderCreateMutation API endpoints are unavailable.

Current Status:

  • The B2B product team confirmed these mutations are not yet available
  • Shopify indicated improvements would come “later this year” (as of early 2024)
  • Developers are advised to monitor the official changelog for updates

Workarounds Being Explored:

  • Using regular order objects combined with custom metaobjects
  • Adjusting incoming inventory quantities via existing API endpoints
  • UI automation tools (AutoIt, Selenium WebDriver) for single-merchant use cases

Business Impact:

  • Multiple users report needing to manually enter POs with 100-200+ line items periodically
  • Use cases include B2B customers managing inventory levels and tracking serial numbers/asset tags

Discussion remains open with no concrete release timeline provided, and users continue requesting updates on API availability.

I need to create purchase orders (https://help.shopify.com/en/manual/products/inventory/purchase-orders) via the Admin API. They have been added to the admin front-end without any of the queries or mutations subsequently made available. When will they be added to a release (even if it’s just in unstable)?

Hi Ryan,

I’ve connected with the b2b product team on this and while these mutations are not currently available, it is possible to adjust incoming quantities via the API, and you can also share the date of arrival. We’ll be improving this experience later this year so keep an eye on our developer changelog.

Hey Liam,

Thank you for checking in with them, it’s good to hear that they are looking to release it this year. For now, my specific workaround will need to use a regular order object and a custom metaobject, but I’ll be keeping my eye on that changelog to get switched over asap once they’re released.

If y’all take in priority suggestions, please give them a +1 from me to pump this update out as soon as they can. Thanks!

@RyanTechLLC If this is for your own merchant usage there’s always tools like autoit,or webdrivers, or browser extensions for automating UI interactions in singular use cases when platforms lack the proper apis.

@PaulNewton , I love using Selenium WebDriver and Microsoft Power Automate for my own automations. This app I’m working on now is for a client’s store, so everything has to be nicely packaged with 0 manual setup required. Running a headless web driver on the server is actually very close to a working solution, the only issue I see is needing to log in to their admin and dealing with password changes.

They want their b2b customers to be able to manage their own inventory levels and place inventory reorders- hence the no-brainer to use a purchase order. I think a regular order with some tags will work fine for now. The most critical part is logging any incoming serial numbers, asset tags, PO numbers, etc. which is where I think the custom metaobject definition will come into play. Still planning this out though.

Hi Liam,
Hope you’re well. Are there any updates on this, in regard to querying and mutating PurchaseOrders?

Hey RyanTechLLC!
Have you found a workaround to create a PO programmatically from an Order?
I need to place a PO with 140 different variants (and quantities) and I want to avoid to loose the entire day entering it by hand.

Thank you for any clue about this!

Hi! Any update on this?
I need to add POs with 100-200 lines periodically and having to do it manually is far from acceptable.

Thank you!

Any update about this?
