## Magento Inventory (MSI)

<Note>
  `Algolia_AlgoliaSearchInventory` is a community-maintained module available on [GitHub](https://github.com/algolia/algoliasearch-inventory-magento-2).
  Algolia contributes to the repository but doesn't provide a product roadmap for the module.
  Its releases don't follow the Algolia/Magento integration release schedule.
</Note>

The Algolia extension supports the [Magento Inventory](https://developer.adobe.com/commerce/php/module-reference/module-inventory/) module.
It's also known as Multi-Source Inventory (MSI).

For more information, see [Inventory Management](https://developer.adobe.com/commerce/webapi/rest/inventory/) in the Magento developer docs.

The MSI features include:

* Different setups for merchants whose stock comes from one or more sources
* Stock tracking through assigned sources
* Concurrent checkout protection
* Shipment matching algorithms

This lets you create several inventory sources and stocks.
You can then manage product availability across your stores.

### Compatibility

MSI changed how Magento determines whether a product is in stock.
To support this behavior, Algolia provides an optional module, `Algolia_AlgoliaSearchInventory`.
This module also keeps older Magento 2 integration versions working.

You can download this module separately with Composer.
Then use it alongside the Algolia extension.

Use `Algolia_AlgoliaSearchInventory` with version 1.12 or later of the Algolia extension.
To find which version to install, check the [compatibility](https://github.com/algolia/algoliasearch-inventory-magento-2#compatibility) list on GitHub.

### Requirements

You can use `Algolia_AlgoliaSearchInventory` if:

* You're using Magento version 2.3 or later
* You're using several sources or stocks to manage your inventory

<Check>
  If you don't use MSI, the `Algolia_AlgoliaSearchInventory` module won't break your indexing process.
  It may still slow it down.
  Only install the module if you're using MSI.
</Check>

### Install the Algolia\_AlgoliaSearchInventory module

```sh Command line icon=square-terminal theme={"system"}
composer require algolia/algoliasearch-inventory-magento-2
php bin/magento module:enable Algolia_AlgoliaSearchInventory
php bin/magento setup:upgrade
php bin/magento setup:static-content:deploy # in case you're on production mode
```

Now Magento handles your sources and stocks as expected.
You can keep using the Algolia extension.

## Backend search adapter

<Note>
  The `Algolia_SearchAdapter` module is an official companion module, available on [GitHub](https://github.com/algolia/algoliasearch-adapter-magento-2).
  Algolia maintains it and aligns it with the Algolia/Magento integration product releases, starting with version 3.18.
</Note>

The Algolia Search Adapter registers Algolia as a native Magento 2 search engine.
It also provides server-side rendering for category pages and search results.
When enabled, Magento's standard product listing blocks query Algolia directly.
This makes the content visible to search engine crawlers, LLM-based discovery tools, and clients that don't run JavaScript.

### Install the Algolia\_SearchAdapter module

```sh icon="square-terminal" theme={"system"}
composer require algolia/algoliasearch-adapter-magento-2
php bin/magento module:enable Algolia_SearchAdapter
php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento cache:flush
```
