What is Etsy API and How It Works
Etsy is a marketplace that enables sellers from all across the globe to promote their handmade products. Even if the business model of this platform is slightly similar to the one offered by eBay or Amazon, Etsy stands out from the crowd by providing an amazing level of value to both sellers and buyers.
According to statistics, Etsy is a $12.5 billion marketplace shaping global eCommerce culture. In 2024, Etsy earned $2.808 billion in revenue, a modest 2.18% growth over the previous year, a decline from the pandemic growth of 2020–2021. With 95.5 million active buyers and 8.1 million sellers, the competition is heating up, and consumer expectations are evolving.
Now, because of its growth, Etsy represents a goldmine for eCommerce software developers like yourself. Connecting your software to this marketplace opens up a whole new array of opportunities, giving you access to all e-store owners on this marketplace and allowing you to expand your range of services. However, to get there from here, you first need to understand how an API integration works.
Etsy API allows developers to retrieve and manage data from Etsy shops using RESTful methods. It supports JSON responses and OAuth authentication, helping your system work with product listings, customer details, order information, and more. By integrating with Etsy API, you gain full control over essential e-store operations.
Why Etsy API Integration Is Crucial for eCommerce Software
As Etsy continues to grow, offering Etsy integration becomes a competitive advantage. It allows your clients to synchronize their Etsy shops with your software, automate business processes, and save time on manual updates. Whether you're developing order management, shipping, or inventory tools — Etsy marketplace integration is the key.
Each shopping platform and marketplace, such as Amazon, Walmart, WooCommerce, or Etsy, has its unique API. Therefore, to work with the sellers on each platform, you need to set up a connection with each API in particular. For example, for Etsy, you need to set up a connection with this marketplace API.
Etsy API is a seamless one that uses a RESTful infrastructure to improve data connection and transfer. It uses JSON-formatted responses to enable you to gain access to all Etsy’s website features, such as shops, public profiles, tags, listings, sales, customers, and favorites.
This API leverages the oAuth method to allow you to easily write and read users’ private and public data, making it super easy for you to gain access to any type of information you might need. Once you access the API, which lies under an “openapi” subdomain, you can start using HTTPS methods to retrieve the information you need. These methods you can use are: PUT, POST, GET and DELETE.

Also, see how you can integrate Etsy and eBay easily with API2Cart, managing products, orders, inventory, and customers across multiple marketplaces without extra development effort.
What is Etsy Integration?
Etsy integration is the process of connecting your software application with the Etsy marketplace using Etsy’s API. This connection allows your software to interact with Etsy’s platform automatically—enabling the retrieval and management of store data such as products, orders, inventory, and customer information.
This allows software developers to automate key Etsy store operations, so sellers don’t have to manage them manually. Instead, everything can be accessed and controlled from within the software itself.
Etsy integration is an essential feature for modern eCommerce software. It allows developers to support their users more fully by connecting directly to one of the world’s most popular marketplaces. Whether you choose to integrate directly via Etsy’s API or use a unified solution, adding Etsy support is a strong move that can help your software stand out and grow in today’s competitive market.
Challenges of Etsy API Integration Development
Direct Etsy API integration requires deep tech expertise and ongoing maintenance. The documentation can be complex, and Etsy’s frequent updates demand constant support. That’s why many companies choose API2Cart to avoid hidden costs and long development cycles.
Benefits of Connecting to Etsy via API2Cart
Etsy integration can unlock new opportunities for your eCommerce software. But doing it directly can be complex and time-consuming. That’s where API2Cart comes in. It’s a unified API solution that enables software developers to integrate their applications with multiple eCommerce platforms, including Etsy, through a single integration. Here’s why software developers choose to integrate Etsy via API2Cart instead of developing direct integrations:
1. Single Integration – Multiple Platforms
With API2Cart, you don’t just get access to Etsy, you connect to 60+ eCommerce platforms and marketplaces, including Shopify, Magento, WooCommerce, BigCommerce, Etsy, Wix, OpenCart, and others - all through one unified API. This drastically reduces the need to build separate integrations for each platform, making it easier to scale your software solution.
2. Faster Time-to-Market
API2Cart provides ready-made API methods for working with Etsy product listings, orders, inventory, shipments, and more. You can start retrieving and managing store data right away without spending weeks studying Etsy’s native API documentation or dealing with edge cases.

Marketplace APIs like Etsy’s frequently change. With API2Cart, their team handles all API updates and version changes for you, so your development team doesn’t need to spend time fixing or rewriting code every time Etsy modifies something.
4. Reduced Development Costs
Building and maintaining a direct Etsy API integration requires significant investment—especially if you need to support other platforms, too. API2Cart eliminates the need for dedicated resources for each individual platform and lowers the overall cost of development.
5. Reliable Support and Documentation
API2Cart offers detailed technical documentation, SDKs, interactive API consoles, and a support team that helps developers resolve integration questions quickly. This allows your developers to focus more on building your product, not troubleshooting marketplace APIs.

You will also have to look after the setup and infrastructure for developing integrations in-house. Further, you will have upgrades and maintenance for each integration to take care of because every time Etsy rolls out a new version of its API, your integration will need an update.
Usage of third-party services like API2Cart
