Maximize Your Revenues with the API

Keyboard_Typing The API (Application Programming Interface) is one of the most powerful ePN tools available. Not only does it give you access to all of eBay’s inventory, but it also enables you to customize listings to optimize your campaigns and improve your conversion rates.

The API allows publishers with deeper programming knowledge to fully customize the user experience, while considerably enhancing your chances to boost your performance. Here are a few things you’ll need to know:

What can I do with the API?

The API is the most open and powerful tool for tailoring eBay listings to work harmoniously with your site. There is also functionality to integrate ePN reports within your own backend systems for a more streamlined way to monitor your performance.

Customizing eBay listings

You can use the API to personalize eBay’s listings according to filters, thus maximizing your performance potential. There are multiple types of calls and filters available for you to experiment with to find the mix that works best for your visitors.

For example, a comparison website might use the API to display eBay products that are sold by top rated sellers, above a certain amount, and with free shipping, which could help drastically improve conversion rates.

How do I access the API?

First, apply to join the Developers Program here. After you have been accepted, go to “My Account” and click on “Generate Productions Keys” to get an Application ID.

Then, begin by picking a call, checking out the sample code and testing using your Application ID.

From there, you can build your app, test it and have it approved by the eBay Developer Program to start making up to 5,000 requests per IP per day. For more details, check out the Checklist for Going Live.
