# Get Started with Commerce Marketplace

Use Commerce Marketplace to manage third-party sellers using a Lightning app.

To learn more, including a detailed guide for marketplace operators, go to [Salesforce Help](https://help.salesforce.com/s/articleView?id=commerce.commerce_marketplace.htm&type=5).

**note:** These guides and API reference are for developers building integrations for Commerce Marketplace.

## Marketplace Integration Toolkit

The Marketplace Integration Toolkit is a reference application. Use it to sync data between B2C Commerce and Commerce Marketplace. To start the setup process, see the [Initial Setup](https://developer.salesforce.com/docs/commerce/marketplace/guide/marketplace-initial-setup.md) guide.

## B2C Commerce Cartridges

We offer a series of cartridges to help developers build their integrations. Each one is responsible for a new service or component that can be added to the storefront. These cartridges can be added to any storefront based on the Storefront Reference Architecture (SFRA).

Available cartridges:

- **Plugin** (`plugin_marketplace_storefront`)
  Customizes the front end. Controls all interactive and visual features, including controllers, templates, and more. Doesn’t process back-end functions.
- **Int** (`int_marketplace`)
  A required cartridge used mostly in the backend for creating requests to the middleware.
- **Buybox** (`plugin_marketplace_buybox`)
  Shows different seller offers in a Product Display Page.
- **Checkout** (`plugin_marketplace_checkout`)
  Splits the cart and the order per seller and allows customers to finish their order. Customers can insert their address, select the better shipping method per seller, review all products added to the cart grouped by sellers and also insert the payment information.
- **BASE** (`int_marketplace_service`)
  An internal cartridge that works as an integration accelerator. The `int_marketplace` cartridge requires the `int_marketplace_service` cartridge.

## Marketplace Seller Integration API

For third-party sellers, we offer a REST API to build custom tooling for managing your items within Commerce Marketplace. For more information, see the [API Reference](https://developer.salesforce.com/docs/commerce/marketplace/references).

## About the Atonit Brand

While using Commerce Marketplace, you’ll see occasional references to Atonit, which was the name of the company that originally developed these technologies. Atonit was acquired by Salesforce in 2022, and we’re still in the process of rebranding.
