Magento2 – Customer Import Using API

This is working for me:

{
   "email": "email@email.com",
   "template": "email_reset",
   "websiteId": 1
}

template - "email_reset" is not real template which you can create in admin. It is constant which I found in AccountManagenet.php.

$product = $objectManager->create('\Magento\Catalog\Model\Product');
        $product->setWebsiteIds(array(1));
        $product->setAttributeSetId(4);
        $product->setTypeId('simple');
        $product->setCreatedAt(strtotime('now')); 
        $product->setName($importProduct[1]); 
        $product->setSku($importProduct[3]);
        $product->setWeight($importProduct[16]);
        $product->setStatus(1);
        $category_id= array(30,24);
        $product->setCategoryIds($category_id); 
        $product->setTaxClassId(0); // (0 - none, 1 - default, 2 - taxable, 4 - shipping)
        $product->setVisibility(4); // catalog and search visibility
        $product->setColor(24);
        $product->setPrice($importProduct[11]) ;
        $product->setCost(1); 
        $product->setMetaTitle($importProduct[1]);
        $product->setMetaKeyword($importProduct[26]);
        $product->setMetaDescription($importProduct[28]);
        $product->setDescription($importProduct[27]);
        $product->setShortDescription($importProduct[27]);

        $product->setStockData(
            array(
            'use_config_manage_stock' => 0, 
            'manage_stock' => 1, // manage stock
            'min_sale_qty' => 1, // Shopping Cart Minimum Qty Allowed 
            'max_sale_qty' => 2, // Shopping Cart Maximum Qty Allowed
            'is_in_stock' => 1, // Stock Availability of product
            'qty' => (int)$importProduct[6]
            )
        );


        $product->save();
        echo "Upload simple product id :: ".$product->getId()."\n";
    }
catch(Exception $e)
{
    echo 'Something failed for product import ' . $importProduct[1] . PHP_EOL;
    print_r($e);
}
