WC REST API – how to add product variations?

Whenever you need to edit a product that already exists, it’s correct to use PUT.

Is WooCommerce related to Jigoshop in any way? Jigoshop is horrible and has no support. Please let me know as I am thinking about converting to WooCommerce.

This I know and PUT works for updating single product and elements of variable product like title, description etc. It also works for updating already existing variation. But when I’m trying to add new variation with following code, it’s not added to the system:

{
    "product": {
        "variations": [
            {
                "regular_price": 123,
                "virtual": true
            }
        ]
    }
}

PUT: https://example.com/wc-api/v3/products/736?consumer_key=ck_123&consumer_secret=cs_123

736 is ID of variable product.

Is there any list of required attributes necessary to create product variation? I also tried to add "attributes" array and it didn’t work either.

@pawelkmpt yet, just use PUT to create the variations on the existing product.
But your code is not enough to create a new variation. That’s the problem ??

Please read the docs: https://woothemes.github.io/woocommerce-rest-api-docs/#products-properties

Missing attributes in your product and variations.

Here an example:

{
  "product": {
    "attributes": [
      {
        "name": "Color",
        "slug": "color",
        "position": "0",
        "visible": false,
        "variation": true,
        "options": [
          "Black",
          "Green"
        ]
      }
    ],
    "default_attributes": [
      {
        "name": "Color",
        "slug": "color",
        "option": "Black"
      }
    ],
    "variations": [
      {
        "regular_price": "123",
        "virtual": true,
        "attributes": [
          {
            "name": "Color",
            "slug": "color",
            "option": "black"
          }
        ]
      },
      {
        "regular_price": "123",
        "virtual": true,
        "attributes": [
          {
            "name": "Color",
            "slug": "color",
            "option": "green"
          }
        ]
      }
    ]
  }
}

@orlando85 WooCommerce born from fork of Jigoshop, but we don’t anything related with Jigoshop anymore.
So, welcome to WooCommerce ??

Well, docs don’t say anywhere which attributes are required for specific actions.
You code doesn’t work either, one more attribute is missing: "type": "variable". When I add it everything works.

See: https://github.com/woothemes/woocommerce/blob/master/includes/api/class-wc-api-products.php#L394

Actually following code is enough to insert variation:

{
  "product": {
    "type": "variable",
    "variations": [
      {
        "virtual": true,
        "regular_price": "123"
      }
    ]
  }
}

so "type": "variable" is a key attribute here.

I’ll add some note about it on the docs.
Thanks ??
