Please send me the sample json file "my-product-data.json".
It's really helpful for me.

Hello, can you please share an json example, i tried to reverse engineer but without success.
Here is what i got so far:

$product_data = array(
        'sku' => '123SKU',
        'categories' => array('size', 'color'),
        'available_attributes' => array('size', 'color'),
        'variations' => array( 
            'size' => array(
                'attributes' => array( 'XL', 'M', 'S' ), 
            ),
            'color' => array(
                'attributes' => array( 'Blue', 'Red', 'Green' )  
            )
        )
)

Thank You.;

Hi.
I can create my product with php successfully, but now I want to set product's attribute and I can't.
To be more clear:
I create some custom attributes in wordpress admin panel, and I want to add values for those attributes in my product, by php.

any help?

{
product_id: product.id,
available_attributes: ["color", "size"],
variation_data: {
attributes: {
color: "Red",
size: "M",
},
sku: "",
regular_price: 200,
sale_price: "",
stock_qty: 8,
},
},

this example to inset attributes and variables in react native.

Thanks man very much :)

Would be nice if you converted this to use WC 3.0 CRUD operations. Much cleaner :)
