POST source-items for update returns 404

Question

I am trying to update the quantity of products using the rest api call: {HostUrl}/rest/default/V1/inventory/source-items with the below data:

{
  "sourceItems": [
    {
      "sku": "EXAMPLE_SKU",
      "quantity": 4,
      "status": 1
    }
  ]
}

However, this is returning a 404 response saying that the route cannot be found. The route appears to be correct according to the Magento 2.4 static api documentation.

Other routes such as {HostUrl}/rest/V1/store/storeViews work without a problem and the permissions for modifying products/inventory have been given, so I'm at a dead end to understanding why this isn't working.

Any solution or advice will be massively appreciated :)

Answer 1

Remove default from the url {HostUrl}/rest/default/V1/inventory/source-items.

Answer 2

as per the devdocs, https://developer.adobe.com/commerce/webapi/rest/inventory/manage-source-items/#assign-products-to-a-source

the source_code param is also needed, regardless of if you're using multiple sources. you can get a list of all sources with /rest/V1/inventory/sources

example:

{
  "sourceItems": [{
    "sku": "myproduct",
    "source_code": "home_source",
    "quantity": "521",
    "status": 1
  }]
}

Check if the following module is present and enabled in your app/etc/config.php
