Why have my configurables stock status Out of Stock

Question

All I found so far is from the User Guide in Step 4 under 2.:

The Quantity is determined by the product variations, so you can leave it blank for now.

The Stock Status of a configurable product is determined by each associated configuration. Because the product was saved without entering a quantity, the Stock Status is now set to “Out of Stock.”

According to this the Quantity is determined by the product variations but how about the Stock Status? If you have variations that are "In Stock" shouldn't be the configurable "In Stock" too?

My background:
Our products are created via rest api like this:

1. All simples
2. The configurables with the simple ids that belong to them in configurable_product_links

In our case all configurables are set to "Out of Stock". Even when I reindex the Stock Status is not getting updated. Is this expected behavior?

I've already tried:

• Clearing cache
• Reindexing

Here an example json we post to create a configurable:

{
  "product": {
    "typeId": "configurable",
    "sku": "sku",
    "status": 1,
    "attributeSetId": 44,
    "name": "Configurable product name",
    "extensionAttributes": {
      "configurable_product_options": [
        {
          "attribute_id": 861,
          "label": "Some Label",
          "values": [
            {
              "value_index": 15929
            },
            {
              "value_index": 15945
            },
            {
              "value_index": 15967
            }
          ]
        }
      ],
      "configurable_product_links": [
        18449,
        18450,
        18451
      ],
      "category_links": [
        {
          "position": 0,
          "category_id": 899
        }
      ]
    },
    "customAttributes": [
      {
        "attributeCode": "description",
        "value": "Our description"
      }
    ]
  }
}

Answer 1

Try to create the configurable product with manage_stock=false it will works as expected!

Answer 2

1) Pass 2 params in headers:

a) Content-Type:application/json b) Authorization: Bearer {token}

2) Create the simple product ============= Payload ==== POST Method = /rest/default/V1/products

{ "product": { "sku": "tester-rj-sm", "name": "Tester Rj Small", "attribute_set_id": 4, "price": 25, "status": 1, "visibility": 1, "type_id": "simple", "weight": "0.5", "extension_attributes": {
"stock_item": { "qty": "10", "is_in_stock": true } }, "custom_attributes": [ { "attribute_code": "description", "value": "Long description......." }, { "attribute_code": "tax_class_id", "value": "2" }, { "attribute_code": "size", "value": "507" } ] } }

3) Create the configurable product ============= Payload ==== POST Method = /rest/default/V1/products

{ "product": { "sku": "tester-rj1", "name": "Tester Rj", "attribute_set_id": 4, "status": 1, "visibility": 4, "type_id": "configurable", "weight": "0.5", "extension_attributes": { "stock_item": {"itemId":null,"productId":0,"stockId":1,"qty":0,"isInStock":true,"isQtyDecimal":true,"showDefaultNotificationMessage":false, "useConfigMinQty":true,"minQty":1,"useConfigMinSaleQty":1,"minSaleQty":1,"useConfigMaxSaleQty":false,"maxSaleQty":0,"useConfigBackorders":true, "backorders":0,"useConfigNotifyStockQty":true,"notifyStockQty":1,"useConfigQtyIncrements":true,"qtyIncrements":1,"useConfigEnableQtyInc":true,"enableQtyIncrements":true,"useConfigManageStock":true,"manageStock":true, "lowStockDate":null,"isDecimalDivided":true,"stockStatusChangedAuto":0,"extensionAttributes":null} },
"custom_attributes": [ { "attribute_code": "description", "value": "Long description....." }, { "attribute_code": "tax_class_id", "value": "2" } ] } }

4) Define configurable product options ======= Payload ====== POST Method = /rest/default/V1/configurable-products/tester-rj1/options

{ "option": { "attribute_id": "180", "label": "Size", "position": 0, "is_use_default": true, "values": [ { "value_index": 507 } ] } }

5) Link the simple products to the configurable product === Payload ==== POST Method = /rest/default/V1/configurable-products/tester-rj1/child

{ "childSku": "tester-rj-sm" }

Above are the steps to create configurable product using Magento 2.X.X rest API. This way configurable product will be In Stock and will be available for purchase automatically.
