Updating Product Special Prices in Magento 2

To set or change a product's special price in Magento 2, you can use the SpecialPriceInterface. This interface allows you to programmatically manage special pricing for products.

Method Definition:

public function update(array $prices);

Parameters

Key	Type	Description
`store_id`	int	The ID of the store where the special price applies.
`sku`	string	The Stock Keeping Unit of the product.
`price`	float	The special price value.
`price_from`	string	The start date for the special price in 'Y-m-d H:i:s' format (UTC).
`price_to`	string	The end date for the special price in 'Y-m-d H:i:s' format (UTC).

Example Code to Update Special Price:

<?php

namespace Vendor\Module\Model;

use Psr\Log\LoggerInterface;

use Magento\Catalog\Api\SpecialPriceManagementInterface;

use Magento\Catalog\Api\Data\SpecialPriceInterfaceFactory;

use Magento\Framework\Exception\CouldNotSaveException;

class UpdateSpecialPrice

{

private $specialPriceManagement;

private $specialPriceFactory;

private $logger;

public function __construct(

SpecialPriceManagementInterface $specialPriceManagement,

SpecialPriceInterfaceFactory $specialPriceFactory,

LoggerInterface $logger

) {

$this->specialPriceManagement = $specialPriceManagement;

$this->specialPriceFactory = $specialPriceFactory;

$this->logger = $logger;

}

public function applySpecialPrice()

{

$sku = '24-MB01';

$price = 10.99;

$priceFrom = '2025-02-01';

$priceTo = '2025-02-28';

try {

$specialPrice = $this->specialPriceFactory->create();

$specialPrice->setSku($sku)

->setStoreId(0)

->setPrice($price)

->setPriceFrom($priceFrom)

->setPriceTo($priceTo);

$this->specialPriceManagement->update([$specialPrice]);

return true;

} catch (CouldNotSaveException $e) {

$this->logger->error(__('Error updating special price: %1', $e->getMessage()));

} catch (\Exception $e) {

$this->logger->error(__('Unexpected error: %1', $e->getMessage()));

}

return false;

}

In this example, replace '24-MB01' with your product's SKU. The price_from and price_to fields define the period during which the special price is active. If these fields are omitted, the special price will be applied immediately and remain until changed.
