With increasing competition in the eCommerce industry, the need for marketplace integration is at its peak. And why shouldn’t it be?

eCommerce vendors like you need to serve their clients with full-fledged software to streamline their business operations. When you integrate with eCommerce marketplaces, you add extra functionality to your software which proves indispensable for the e-retailers. Therefore, if your clients have e-stores on Etsy, you need Etsy API integration to provide them with your software core functionality.

What is Etsy Marketplace API Integration?

Etsy recently gathered 96.3 million buyers with annual revenue of $2.3 billion. In addition, it features more than 4.3 million sellers. From a simple website back in 2015 to a vast marketplace today, Etsy has come a long way. Therefore, Etsy API integration can prove to be a profitable affair for any eCommerce SaaS business.

Let’s explore the benefits of Etsy API integration development:

  1. It can get you international exposure for your business. It is used by e-retailers from various countries who can be your software prospective clients.

API of Etsy

The API of Etsy helps in connecting the eCommerce software to this marketplace. It acts as the intermediary between the software and the marketplace. With Etsy API, you get direct access to data related to products, categories, orders, etc.

Just like every other marketplace API, Etsy has a unique API that functions particularly for the Etsy marketplace and helps developers connect with the platform. Etsy API uses REST architecture for data transfer and a secure and constraint-based data connection.

It allows JSON format for data resources and through it helps you to access data related to sales, customers, listings, tags, public profiles, shops, and favorites. Further, Etsy API uses the OAuth method for authenticating you to read and write both public and private data of the customers on the e-stores.

For information retrieval, Etsy API allows the use of HTTP methods like PUT, POST, GET, and DELETE. It works on the request and response model wherein a successful response comes with 200 codes, and an unsuccessful one comes with a 404 error code.

How to Develop Integration with Etsy?

Etsy API integration can be developed in two different ways. One is in-house integration development, and the other one is development via third-party services. Let’s take a look at both approaches.

In-house integration development

In in-house integration development, you will have to hire a development team and train it to build integrations for you. You have to look for advanced developers who can code integrations and onboard them along with training them according to your client’s requirements.

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

Choosing Etsy API integration development via a third-party service, you need to find a service provider to develop integrations for you. Here, you don’t need to hire or train a development team or pay them a salary. Instead, everything will be taken care of by the service provider.

One of such services is API2Cart, which allows B2B eCommerce software vendors to develop integration with more than 40 eCommerce platforms and marketplaces in one go.

The platforms include Amazon, eBay, Magento, Shopify, WooCommerce, and Etsy. API2Cart provides more than 100 API methods to help vendors access the required data from these platforms.

Moreover, API2Cart also looks after the setup and infrastructure on its own, so you don’t have to spend money from your budget.

API2Cart makes it easy for the vendors to make their software access data related to products, orders, customers, categories, shipments, etc., from the eCommerce platforms and marketplaces like Etsy.


Etsy API integration development can be challenging if you don’t choose the right approach like a third-party service provider. But its importance cannot be overlooked, considering the benefits it brings to your SaaS business.
