But when I'm trying to save this product, the error Option values are not specified. appear. Can someone help me to save the product or just release another way to save a configurable product. Thanks!

You have to set attribute id and its value to it. For example this array of data:

public function getProductData($data = [])
{
 $productData = [
 'stock_data' => [
 'min_qty_allowed_in_shopping_cart' => [
 [
 'record_id' => "0",
 'customer_group_id' => "32000",
 'min_sale_qty' => "",
 ]
 ],
 'deferred_stock_update' => "1",
 'use_config_deferred_stock_update' => "1",
 'min_qty' => "0",
 'max_sale_qty' => "10000",
 'notify_stock_qty' => "1",
 'qty_increments' => "1",
 'min_sale_qty' => "1",
 'use_config_manage_stock' => "1",
 'manage_stock' => "1",
 'use_config_min_qty' => "1",
 'use_config_max_sale_qty' => "1",
 'use_config_backorders' => "1",
 'backorders' => "0",
 'use_config_notify_stock_qty' => "1",
 'use_config_enable_qty_inc' => "1",
 'enable_qty_increments' => "0",
 'use_config_qty_increments' => "1",
 'use_config_min_sale_qty' => "1",
 'is_qty_decimal' => "0",
 'is_decimal_divided' => "0",
 ],
 'use_config_is_returnable' => "1",
 'gift_wrapping_available' => "1",
 'use_config_gift_wrapping_available' => "1",
 'gift_message_available' => "0",
 'use_config_gift_message_available' => "1",
 'links_title' => "Links",
 'links_purchased_separately' => "0",
 'samples_title' => "Samples",
 'attribute_set_id' => "4",
 'status' => $this->isParentProductEnable(),
 'affect_product_custom_options' => "1",
 'name' => $data['title'],
 'title_rewrite' => "",
 'price' => "100",
 'weight' => "",
 'url_key' => "",
 'gift_wrapping_price' => "",
 'special_price' => "",
 'cost' => "",
 'msrp' => "",
 'quantity_and_stock_status' => [
 'qty' => "",
 'is_in_stock' => "1"
 ],
 'is_returnable' => "2",
 'website_ids' => [$this->getWebsiteId($data['division'])],
 'tax_class_id' => "2",
 'product_has_weight' => "1",
 'visibility' => "4",
 'color' => "49",
 'size' => "91",
 'options_container' => "container2",
 'weltpixel_exclude_from_sitemap' => "0",
 'msrp_display_actual_price_type' => "0",
 'description' => "",
 'short_description' => "",
 'custom_layout_update' => "",
 'sku' => $data['product_code'],
 'meta_title' => $data['title'],
 'meta_keyword' => $data['title'],
 'meta_description' => "",
 'configurable_attributes_data' => [
 self::COLOR_ATTRIBUTE_ID => [
 'attribute_id' => self::COLOR_ATTRIBUTE_ID,
 'code' => "color",
 'label' => "Color",
 'position' => "0",
 'values' => $this->getColorValue($data)
 ],
 self::SIZE_ATTRIBUTE_ID => [
 'attribute_id' => self::SIZE_ATTRIBUTE_ID,
 'code' => "size",
 'label' => "Size",
 'position' => "1",
 'values' => $this->getSizeValue($data)
 ]
 ],
 'associated_product_ids_serialized' => "[]",
 'configurable-matrix-serialized' => $this->getConfigurableMatrix($data)
 ];
 return $productData;
}

The important part is here:

 'configurable_attributes_data' => [
 self::COLOR_ATTRIBUTE_ID => [
 'attribute_id' => self::COLOR_ATTRIBUTE_ID,
 'code' => "color",
 'label' => "Color",
 'position' => "0",
 'values' => $this->getColorValue($data)
 ],
 self::SIZE_ATTRIBUTE_ID => [
 'attribute_id' => self::SIZE_ATTRIBUTE_ID,
 'code' => "size",
 'label' => "Size",
 'position' => "1",
 'values' => $this->getSizeValue($data)
 ]
 ],
'configurable-matrix-serialized' => $this->getConfigurableMatrix($data)

That would be the data indicating the simple products data.

Updated: These are methods for building simple products with configurable product:

private function getConfigurableMatrix($data)
{
 $jsonOutput = "[";
 // Get pair codes for matrix
 $colors = $data['colors'];
 $sizes = $this->getSizeArray($colors)['sizes'];
 $status = $this->isChildProductEnable();
 foreach ($colors as $color) {
 foreach ($sizes as $size) {
 $colorParam = [
 'id' => $this->getColorOptionId($color['color_id']),
 'lable' => $color['color_id']
 ];
 $sizeParam = [
 'id' => $this->getSizeOptionId($size['size']),
 'lable' => $size['size']
 ];
 $weight = $size['weight'] ? $size['weight'] : $this->getDefaultWeight();
 $jsonOutput .= $this->getConfigurableMatrixItem($data['title'], $size['sku'], $colorParam, $sizeParam, $size['quantity'], $weight, $size['price'], $status) . ",";
 }
 }
 $jsonOutput = rtrim($jsonOutput, ',');
 $jsonOutput .= "]";
 return $jsonOutput;
}
private function getConfigurableMatrixItem($name, $sku, $color = [], $size = [], $qty, $weight, $price, $status = 1)
{
 $item = [
 "id" => null,
 "product_link" => "",
 "name" => "$name {$color['lable']} {$size['lable']}",
 "sku" => "$sku",
 "status" => $status,
 "price" => "$price",
 "price_currency" => "$",
 "price_string" => "$$price",
 "weight" => "$weight",
 "qty" => "$qty",
 "variationKey" => "{$size['id']}-{$color['id']}",
 "configurable_attribute" => "{\"color\":\"{$color['id']}\",\"size\":\"{$size['id']}\"}",
 "thumbnail_image" => "",
 "media_gallery" => [
 "images" => []
 ],
 "image" => [],
 "attributes" => "Color : {$color['lable']}, Size: {$size['lable']}",
 "was_changed" => true,
 "canEdit" => 1,
 "newProduct" => 1,
 "record_id" => 0
 ];
 return json_encode($item);
}
private function getSizeOptionId($labelSize)
{
 if ($labelSize == '') return "";
 $attribute = $this->_eavConfig->getAttribute('catalog_product', 'size');
 $optionId = $attribute->getSource()->getOptionId($labelSize);
 if (!$optionId) {
 // Create a new Option
 $option['attribute_id'] = $attribute->getId();
 //$option['value'][$lableSize][0] = $lableSize;
 $option['value']['size'][0] = $labelSize;
 $eavSetup = $this->_eavSetupFactory->create();
 $eavSetup->addAttributeOption($option);
 $this->_eavConfig = $this->createObject('\Magento\Eav\Model\Config');
 $attribute = $this->_eavConfig->getAttribute('catalog_product', 'size');
 $optionId = $attribute->getSource()->getOptionId($labelSize);
 $this->insertSwatch($optionId, 0, $labelSize);
 }
 return $optionId;
}
private function getColorOptionId($labelColor)
{
 if ($labelColor == '') return "";
 $attribute = $this->_eavConfig->getAttribute('catalog_product', 'color');
 $optionId = $attribute->getSource()->getOptionId($labelColor);
 if (!$optionId) {
 // Create a new Option
 $option['attribute_id'] = $attribute->getId();
 //$option['value'][$labelColor][0] = $labelColor;
 $option['value']['color'][0] = $labelColor;
 $eavSetup = $this->_eavSetupFactory->create();
 $eavSetup->addAttributeOption($option);
 $this->_eavConfig = $this->createObject('\Magento\Eav\Model\Config');
 $attribute = $this->_eavConfig->getAttribute('catalog_product', 'color');
 $optionId = $attribute->getSource()->getOptionId($labelColor);
 $this->insertSwatch($optionId);
 }
 return $optionId;
}
private function insertSwatch($optionId, $type = 1, $value = "#ffffff")
{
 $swatch = $this->createObject('Magento\Swatches\Model\Swatch');
 $swatch->setData([
 'option_id' => $optionId,
 'store_id' => 0,
 'type' => $type,
 'value' => $value
 ]);
 $swatch->save();
}

• Nero Phung: How can I call the function: $this->getConfigurableMatrix($data)
• Toan Tam: This is my function to build the json data for simple product. Do you want to see it ?
• Nero Phung: Of course yes!!
• Toan Tam: please, see my updated answer
• Toan Tam: Any luck @NeroPhung ?
