3rd party fulfillment partner is unable to automatically update order information after fulfillment

[BentoB]

I'm working with a 3rd party fulfillment partner at the moment. They created a custom app to integrate with our shop and fulfill our orders. The app should be pulling order information and update the order's fulfillment statues and add tracking numbers.

Currently it is only pulling order information but they are not able to automatically update the order's fulfillment statues and add tracking numbers to the order. Here is some additional information they have given us

• Language being use – REST
• Development is making a POST call with the shop URL to push the data.
• Error seems to be related to product inventory but they said they are unable to update the location id in the app/api
  • {
    "errors": {
    "base": ["None of the items are stocked at the new location."]
    }
    }

As this is a public post, we're not sure if there's any further information that can be safely posted.

Hi @BentoB , It might be a good idea to suggest that the developer for the custom app post / ask questions regarding any issue they are running into to get advice from other developers on the forums here. In this case it is not fully clear what process they are following. Although for that error I did find a previous forum post where other developers had assistance to resolve it here. https://community.shopify.com/c/shopify-apis-and-sdks/quot-errors-quot-quot-base-quot-quot-none-of-t... This might also be relevant to their issues.
