WeltPixel Marketplace extensions are compatible with **Magento 2.3.X – 2.4.X**. > Always install on a **development/staging server first**, then move to production after verifying functionality. --- ## Step 2 — Configure Authentication Keys Ensure your **Magento Marketplace Authentication Keys** are configured on your instance. If keys are missing or misconfigured, Composer may return a **“no matching package found”** error. Refer to [Magento Documentation](https://devdocs.magento.com/guides/v2.4/install-gde/prereq/connect-auth.html) for instructions on generating and adding these keys. --- ## Step 3 — Install the Extension Navigate to the root of your Magento project and run the following commands. For example, to install the **Layered Navigation** extension: composer require weltpixel/m2-weltpixel-layered-navigation php bin/magento setup:upgrade php bin/magento setup:di:compile php bin/magento setup:static-content:deploy -f --- # Installing Manually via SSH (legacy, before 1.16.0) Manual installation is no longer offered for paid products. Since 1.16.0, paid WeltPixel extensions and themes install and update via Composer only. If you purchased directly from [weltpixel.com](https://www.weltpixel.com/), or migrated your Marketplace purchase to your WeltPixel account, get Composer access under **My Products** at [account.weltpixel.com](https://account.weltpixel.com). If you’ve purchased from the Marketplace and would like to migrate, see this guide: [Manual (SSH) Installation if product is purchased from Magento Marketplace](https://help.weltpixel.com/en/article/manual-ssh-installation-if-product-is-purchased-from-magento-marketplace-fu0zvy/?bust=1758026309384) --- # License Key for Paid Extensions Paid extensions purchased via the Marketplace require a **WeltPixel License Key**. To generate your license key, see this guide: [How to generate a license key and access the latest version of a WeltPixel product if purchased via the Magento Marketplace](https://support.weltpixel.com/hc/en-us/articles/115004378627-How-to-generate-a-license-key-and-access-the-latest-version-of-a-WeltPixel-product-if-purchased-via-the-Magento-Marketplace) --- # Deprecated Method Magento has removed the **Web Setup Wizard**, but for reference, the legacy installation method is documented below. After purchase, you would be redirected to the Marketplace order confirmation page: 1.
