Top Product Data APIs Ecommerce Marketplaces Can Offer Their Partners

The ability to acquire, manage and utilize product data is crucial to the success of your marketplace. Marketplace operators are currently being offered a wide range of eCommerce APIs. What do the best eCommerce platform APIs have to offer and which of these are most suited to your needs?

Leading enterprises such as Amazon, Walmart and eBay have developed outstanding eCommerce APIs. Let’s take a look at their features and understand how your marketplace can benefit from them.

What are product data APIs?

Product data APIs are a powerful tool for eCommerce businesses that allow them to access product information and other relevant data from a variety of sources. Essentially, an API (Application Programming Interface) is a set of protocols that enable different software applications to communicate with each other. In the context of eCommerce, product data APIs allow businesses to easily access product information, including price, availability, and other relevant data, from a variety of sources, such as suppliers or other eCommerce platforms.

Benefits of product data APIs for eCommerce marketplaces

Improved efficiency

One of the primary benefits of using product data APIs is improved efficiency. By automating the process of accessing and updating product information, businesses can save time and reduce the risk of errors. For example, instead of manually entering product data into your eCommerce platform, you can use a product data API to automatically import product information from a supplier’s database. This can save a significant amount of time and resources, allowing you to focus on other areas of your business.

Enhanced customer experience

In addition to improving efficiency, product data APIs can also help enhance the customer experience. By providing accurate and up-to-date product information, businesses can improve the customer’s online shopping experience, leading to higher conversion rates and increased customer loyalty. For example, if a customer sees that a product is out of stock or has an incorrect price, they may become frustrated and abandon their purchase. By using a product data API, you can ensure that your customers always have access to accurate and up-to-date product information, improving their overall experience with your brand.

Increased profitability

Product data APIs can also help increase profitability by providing businesses with valuable insights into product performance and trends. By analyzing data from a variety of sources, businesses can identify which products are selling well, which products are underperforming, and make data-driven decisions to optimize their product offerings. Additionally, by automating the process of accessing and updating product data, businesses can save time and resources, allowing them to focus on other areas of their business, such as marketing and customer service.

Amazon’s Product Advertising and MWS API 

With 310 million monthly users, Amazon has massive appeal for sellers and buyers alike. Free Amazon MWS data can be used to create listings, fetch orders, get payments, produce reports, and more. MWS API data enables sellers to increase selling efficiency, reduce manpower expenses, and improve response time. By studying eCommerce data attributes, applications can be developed to list products for sale, set product prices, retrieve information for order fulfillment, generate reports, and more. 

The Amazon Advertising API automates scales for affiliates, and optimizes advertising results. This API yields campaign and performance data for sponsored products, brands, and display, with programmatic access for campaign management. Advertisers have the ability to manage ads or ad groups based on predefined conditions.

Walmart’s Open API

The Walmart Open API provides access to the marketplace’s extensive product catalog, thereby enabling digital distribution partners to earn affiliate revenues from customer referrals. Walmart is very restrictive in providing access to that API and it’s nothing but open.

Developers can utilize a variety of APIs to acquire crucial Walmart API data, promote sales, and improve the user experience:

Lookup API –  This product price API features the price and availability of each item. 

Search API  – This product lookup API enables a text search to be conducted on the catalogue, which returns matching products on sale. 

Taxonomy API – This API reveals’s category taxonomy which is used to categorize items.

Trending API – This eCommerce API features trending items on

Reviews API – This API provides user reviews of products.

eBay’s Buy and Sell APIs

eBay currently has 177 million active monthly users. Its free Sell APIs provide sellers and third-party developers with all the capabilities needed to manage the vendor’s end-to-end eBay business. Sell APIs are focused on product catalogs (structured data), inventory on-boarding, and management capabilities. It employs a SKU-driven approach to manage purchase orders, fulfillment and returns. 

eBay’s Buy APIs enable vendors to create buying experiences outside of the site. Users can search for, select, and buy eBay items based on eBay API data. Sellers can mirror and display the contents of the items in an eBay category, provide marketing data to drive conversions, and track orders, all from within the seller’s own website. eBay’s Buy APIs offer shoppers the option to buy eBay sellers’ items at any location including social sites.

eCommerce API: What it is & Why You Should Use One

eCommerce API

In today’s digital world, eCommerce is the new norm. The Internet has revolutionized the way businesses operate and consumers shop, making it easier for companies to reach a much larger audience. As eCommerce continues to grow, businesses are increasingly looking for ways to streamline the buying and selling process. This is where an eCommerce API  comes in. An eCommerce API is a set of tools that allows developers to integrate eCommerce functionalities into their own applications and websites.

APIs, or application programming interfaces, play a crucial role in modern web development and digital commerce. They provide a bridge between different software systems, allowing them to communicate and exchange data with one another.

What is an eCommerce API?

An eCommerce API is a set of programming tools and standards that allow developers to integrate eCommerce functionalities into their own applications and websites. It essentially allows businesses to interact with their customers and provide them with a seamless shopping experience. APIs are generally used to facilitate the integration of third-party services into an existing application. Businesses may use an eCommerce API to integrate a payment gateway, shipping provider, or customer service software into their own website.

By using an API, developers can build applications that interact with an online store’s platform and functions, such as product listings, customer accounts, and checkout processes. This allows developers to create applications that can provide a seamless shopping experience for customers.

For example, let’s say you have a web store that sells clothes. You can use an eCommerce API to create a mobile app that allows customers to browse your store’s inventory, complete their purchases, and even track their orders. This would be an example of how an API can help to provide a better shopping experience for your customers.

Why Should Businesses Use an eCommerce API?

There are many advantages of using an eCommerce API, more than simplifying the integration of third-party services into a business’s website or application. 

Improved User Experience

API integrations help to improve the user experience by allowing for seamless navigation and a more intuitive user interface. This is because API integrations help to integrate different software systems and bring together all of the different elements of the website into a single, cohesive platform.

Increased Efficiency

API integrations help to streamline operations and automate certain processes, which in turn leads to increased efficiency. For example, an API integration between a website and a payment gateway can help to automate the process of processing payments, saving time and reducing the risk of errors.

Better Data Management

API integrations help to ensure that data is consistent and up-to-date across all systems. This is because the API acts as a bridge between the different software systems, ensuring that data is passed back and forth accurately and in real-time, it can help businesses to stay up to date with the latest trends and technologies, as APIs are constantly being updated to include the latest features and services.  

Enhanced Security

API integrations can help to enhance the security of an ecommerce website by allowing for secure communication between different systems. This helps to reduce the risk of data breaches and other security incidents. By using a secure eCommerce API, businesses can ensure that customer data is kept secure and private. 

Save Time and Money

By using an API, businesses can avoid the need to manually integrate third-party services, which can be time-consuming and costly. APIs also help online retailers get more insight into their customers so they can offer them products customized to meet their needs.

Types of eCommerce APIs

There are several different types of eCommerce APIs available. 

  • Payment API, which allows businesses to securely process payments and accept credit cards, PayPal, and other payment methods. Another type of API is the Shipping API, which allows businesses to integrate shipping providers, such as UPS and FedEx, into their own website. 
  • Inventory API is another popular type of API. This API allows businesses to keep track of their inventory and automatically update the inventory count on their website. The Customer API is another popular type of API. This API allows businesses to keep track of customer information, such as order history and customer profiles. 
  • Analytics API is a type of API that allows businesses to track and analyze customer data. This data can be used to make informed decisions about marketing strategies and product development.
  • Shipping APIs: These APIs allow for integration with shipping carriers, enabling real-time shipping quotes and order tracking on an e-commerce website.
  • Product APIs: These APIs allow for integration with product catalogs, enabling the display of product information and images on an e-commerce website.
  • CRM API: This type of API integration helps to integrate an eCommerce website with a CRM (Customer Relationship Management) system. This helps to automate the process of managing customer interactions, reducing the risk of errors and improving the overall customer experience.

How to Choose the Right API for E-commerce Website Development

When choosing an API for e-commerce website development, there are several factors to consider, including:

  • Integration: The API should be easy to integrate with other systems, such as payment gateways and shipping carriers.
  • Security: The API should have robust security features to protect sensitive information during transactions.

Benefits To Using an API-First Strategy

Over the past few years, eCommerce businesses have had to deploy new digital technologies to better serve their customers and stay one step ahead of their competitors.

As such, many eCommerce providers have adopted application programming interfaces (APIs) to integrate their software with such shopping platforms as Shopify, Magento, eBay, Amazon, and more. This eCommerce API integration works as a data transfer bridge between the eCommerce shopping platforms and the eCommerce tools, enabling the vendors to provide their customers with the functionality of their platforms.

An API is a set of functions that lets an application interact with operating systems, microservices, external applications, or data. Put simply, APIs allow software to “talk to” and interact with each other. An API for an eCommerce website connects consumers and eCommerce companies by transforming data into valuable business information.

Participating in the API economy is critical to the long-term success of eCommerce vendors as it allows them to connect to tools that help them as well as their customers operate more efficiently. The key to this, however, is using an API-first strategy. 


Benefits of an API-first strategy

Generally, software vendors add APIs on top of their platforms, allowing customers to access some of their software’s underlying functionality but not all the functionality. The API-first strategy makes system integration easier. 

An API-first strategy ensures that customers can access all of the functionality of the vendors’ software through the APIs. This API-first strategy enables eCommerce vendors to create and extend the solution they need to develop to meet their needs as well as the needs of their customers. Not only does the API-first approach improve the development of a solution, it also makes the development process more agile.

Today, applications must not only be well-designed but they have to be on the market within six months. Another benefit of an API-first strategy is that it allows companies to get their products to market faster and it enables customers to derive value more quickly from those products. 

And an API-first model allows developers to customize the features of their solutions according to the business needs of their clients. API-first also makes it easier for developers to make improvements and adjustments to the solutions without having to re-architect the entire system to meet the ever-changing business needs of their customers

The following are benefits of an API-first strategy for eCommerce vendors:

  • Saves time and money on developing applications and rolling out updates. 
  • Changes to the API happen simultaneously across all applications. 
  • Enables automation, which accelerates production.
  • Developers don’t have to build new programs for each application.

Benefits of an API-first approach for eCommerce companies:

  • Lets teams identify design or programming flaws before rolling out applications to customers. 
  • User-facing information looks the same across all platforms. 
  • Website content can be customized to meet the needs of returning customers and website visitors.
  • Improves user experience, as APIs let companies offer customers more services in less time.

Importance of a product price API strategy 

Price monitoring software enables eCommerce companies to monitor the changes in their competitors’ prices in real time. It also gives them real-time insights into stock availability, promotions, and other information eCommerce companies can use to optimize their pricing strategies on the fly.

It’s important for eCommerce companies to use price-monitoring APIs that provide up-to-date eCommerce data that collects information from large retailers and eCommerce marketplaces. This includes information about the top-selling products, product availability, shipping costs, and more. 

Price monitoring APIs also allow eCommerce retailers to trace the pricing history of any product for a specific time period. In addition, the automated price tracing capabilities help organizations save time and money on competitive analysis.


By adopting an API-first development strategy, eCommerce vendors will have agility to meet ever-changing customer expectations and remain competitive in the market. An API-first strategy gives online retailers more control over the selling experience and offers them more options when it comes to scaling up and improving services. APIs also help online retailers get more insight into their customers so they can offer them products customized to meet their needs.

API tools enable online retailers to build more scalable and robust eCommerce platforms that are critical in today’s business climate.
