Business Benefits of API Integrations 

An online store or marketplace requires multiple business processes to function in cohesion.

Some of these benefits are discussed below:


Some Marketplace integrations can be configured to enable the automation of marketplace functions. Automation simplifies the complexities of processes and adds value to the e-business.

For instance, imagine a scenario where there are hundreds of sellers in a multi-vendor platform. A marketplace owner manually transferring the outstanding payments to each account of the sellers will be a time-consuming process. This process can be easily streamlined with the integration of split payment gateway like Stripe Connect, saving the company precious time and resources.  

Automation increases efficiency, reduces manpower costs for the marketplace owner and the vendors, and reduces errors a manual process might entail

Once the eCommerce store scales up, automation is the best option to assist in most of the e-business’ functions. 

Unified Platform

These integrations enable the admin of the marketplace to control the business processes without having to leave the platform, further increasing efficiency. All processes of the marketplace are centralized and unified.

A unified platform also streamlines the workflow of the marketplace. 

For instance, if the accounting API is integrated with the marketplace, each order placed on the marketplace will be automatically updated in the firm’s accounts. 

This will eliminate errors, fasten the process, and most importantly, changes in the accounts would happen vis-a-vis changes in the order system of the marketplace. 

Better Customer Experience 

Ecommerce shopping has leveraged a unique shopping experience to the customers. An eCommerce platform can be customized via marketplace integrations to enhance buyer experience. 

For instance, customers get to search for products or services based on their location, personalizing the shopping experience. They can pay via payment modes that are convenient to them. The customers can also get live product-tracking information. These are some features that enhance the buyer experience. These features can be facilitated by marketplace integrations. 

A better buyer experience leads to better conversion rates and increases customer loyalty by making the customer look forward to shopping from the marketplace.

Enhanced Business Opportunities 

The biggest boom of eCommerce is that it doesn’t confine a business to a particular geographical location as a physical store would. 

However, when an eCommerce store ventures into new markets to enhance the business reach, it is met by challenges of different tax structures, language barriers, and others.

eCommerce integrations bring forth functionalities like automated tax information, translation of text on the website based on location of the buyer, SEO and marketing features, and others.

These features enable a business to transcend boundaries and increase opportunities to scale up its operations by venturing into newer markets. 

 Facilitates Business Management

  • Business analytics 

These are some of the features that facilitate the management of an eCommerce marketplace. 

Revenue Models of Marketplace Integrations  

By considering all the benefits of third-party integrations, it is safe to assume that they are integral to the marketplace. 

Third-party companies use multiple revenue models to charge for their services. The most popular revenue models used by these companies are as follows. 

Subscription Model 

The companies that implement this model charge a recurring subscription fee to the online shops that avail their services. For instance, 

Volume-based Model  

The companies that charge based on this model, levy a fee per transaction. For instance, payment gateways like Stripe, Paypal, and some others are free to sign up and don’t charge monthly. Rather, these payment gateways charge for each transaction that takes place on the e-store using their payment gateways.
