WooCommerce REST API – Create Products with Attributes

There are two types of attributes in WooCommerce – custom attributes and predefined ones. Custom attributes can be created individually on the product pages, to create a predefined attribute, go to Products — Attributes in admin menu.

$api_response = wp_remote_post( 'https://rudrastyh.com/wp-json/wc/v2/products', array(
	'headers' => array(
		'Authorization' => 'Basic ' . base64_encode( 'KEY:SECRET' )
	),
	'body' => array(
    		'name' => 'My test2',
  		'regular_price' => '21.99',
		'attributes' => array(
			array(
      				'name' => 'Color', // parameter for custom attributes
      				'visible' => true, // default: false
      				'options' => array(
        				'black',
        				'blue'
				)
			)
		)
	)
) );

$body = json_decode( $api_response['body'] );
//print_r( $body );

if( wp_remote_retrieve_response_message( $api_response ) === 'Created' ) {
	echo 'The product ' . $body->name . ' has been created successfully';
}

If you go to the edit product page, you will see something like this on the Attributes tab:

Add Predefined Attributes to already Existing Products

If you want to use already existing attribute, you have to specify its ID which can be found on the Products — Attributes page, just find the attribute you need, click the Edit button and look at the URL.


$api_response = wp_remote_post( 'https://rudrastyh.com/wp-json/wc/v2/products/PRODUCT ID', array(
	'headers' => array(
		'Authorization' => 'Basic ' . base64_encode( 'KEY:SECRET' )
	),
	'body' => array(
		'attributes' => array(
			array(
      				'name' => 'Color',
				'position' => 1,
      				'visible' => true, // default: false
      				'options' => array(
        				'black',
        				'blue'
				)
			),
			array(
      				'id' => '2',
				'position' => 0,
				'variation' => true, // for variative products in case you would like to use it for variations
      				'options' => array(
        				'Big',
					'SuperBig' // if the attribute term doesn't exist, it will be created
				)
			)
		)
	)
) );

$body = json_decode( $api_response['body'] );
//print_r( $body );

if( wp_remote_retrieve_response_message( $api_response ) === 'OK' ) {
	echo 'The product ' . $body->name . ' has been updated';
}
