# About the Marketplace Seller Integration API

This document aims to help sellers who wish to perform the management of their items within Commerce Marketplace through a custom integration.

The following documentation focuses on the basic flow for the integration of the seller data, including example requests and responses.

The Marketplace Seller Integration API is based on the main REST API from Salesforce. For more information, see the [REST API Developer Guide](https://developer.salesforce.com/docs/atlas.en-us.api_rest.meta/api_rest/intro_what_is_rest_api.htm).

## Authorization

To use the API, you must authenticate using the **Login** and **Get/Refresh Token** endpoints. These endpoints include an access token in the response that you can supply as a parameter to make authorized requests to the other endpoints. For step-by-step instructions, see the [authorization instructions](https://developer.salesforce.com/docs/atlas.en-us.api_rest.meta/api_rest/quickstart_oauth.htm) for the REST API.

## Rate Limits

To ensure availability and protect from denial of service attacks, requests to the API are rate limited. For details, see the [Limits](https://developer.salesforce.com/docs/atlas.en-us.api_rest.meta/api_rest/resources_limits.htm) page in the REST API Developer Guide.
