After a lot of searching and banging my head everywhere I have successfully implemented to add WooCommerce products through Rest API. Here is my complete working code for reference :-
$api_response = wp_remote_get('www.myapi.com');
$body = wp_remote_retrieve_body($api_response);
/****** API not ready yet...working on it *******/
$data = [
'type' => 'variable',
'description' => 'Trying it out for real',
'short_description' => 'Pellentesque habitant.',
'categories' => [
[
'id' => 37
],
[
'id' => 38
]
],
'images' => [
[
'src' => 'http://demo.woothemes.com/woocommerce/wp-content/uploads/sites/56/2013/06/T_4_front.jpg',
'position' => 0
]
],
'attributes' => [
[
'name' => 'Color',
'position' => 0,
'visible' => true,
'variation' => true,
'options' => [
'Black',
'Green'
]
],
[
'name' => 'Size',
'position' => 0,
'visible' => true,
'variation' => true,
'options' => [
'S',
'M'
]
]
],
'default_attributes' => [
[
'name' => 'Color',
'option' => 'Black'
],
[
'name' => 'Size',
'option' => 'S'
]
],
'variations' => [
[
'regular_price' => '29.98',
'attributes' => [
[
'slug'=>'color',
'name'=>'Color',
'option'=>'Black'
]
]
],
[
'regular_price' => '69.98',
'attributes' => [
[
'slug'=>'color',
'name'=>'Color',
'option'=>'Green'
]
]
]
]
];
$wp_rest_request = new WP_REST_Request( 'POST' );
$wp_rest_request->set_body_params( $data );
$products_controller = new WC_REST_Products_Controller;
$res = $products_controller->create_item( $wp_rest_request );
$res = $res->data;
// The created product must have variations
// If it doesn't, it's the new WC3+ API which forces us to build those manually
if ( !isset( $res['variations'] ) ){
$res['variations'] = array();
}
if ( count( $res['variations'] ) == 0 && count( $data['variations'] ) > 0 ) {
if ( ! isset( $variations_controler ) ) {
$variations_controler = new WC_REST_Product_Variations_Controller();
}
foreach ( $data['variations'] as $variation ) {
$wp_rest_request = new WP_REST_Request( 'POST' );
$variation_rest = array(
'product_id' => $res['id'],
'regular_price' => $variation['regular_price'],
'attributes' => $variation['attributes'],
);
$wp_rest_request->set_body_params( $variation_rest );
$new_variation = $variations_controler->create_item( $wp_rest_request );
$res['variations'][] = $new_variation->data;
}
}
