Tradera's application programming interface (API) and Developer Program

Here you can find information regarding Tradera's application programming interface (API), a source code interface that enables external applications and services to interact with the Tradera platform.

This opens up opportunities for developers to build applications and services that communicate directly with, Sweden’s largest e-commerce marketplace.

The API offers unprecedented opportunities for you as a developer, affiliate or entrepreneur to build a new Tradera business or expand your current business, reach new customers, and create a potential new stream of revenue.

Together with the API, we also have the Tradera Developer Program, a free of charge, membership based program created with the developer community in mind. The Tradera Developer Program provides services and support for individuals and companies who build applications and services using the API. Membership in the program is a prerequisite for using the API.

The Tradera API and Developer Program

The Tradera API was released as a private beta during the fall of 2007, and we are now glad to launch a public version. Tradera developers can sign up to the program and get access to resources which will help you build eg. the following type of applications and services:

  • Seller tools. You can create programs that handle listing of items, payment flows, order handling and shipping.
  • Search applications. You can develop web applications to showcase items currently selling on Tradera, to be placed eg. on your own web site, or in your blog.
  • Affiliate tools. You can develop tools to be used in your affiliate marketing and earn money by sending potential buyers to
  • Mobile applications. You can use the API to build mobile applications to access

Tradera Developer Program is a long term commitment from Tradera, and we will continuosly evolve the functionality of the API and the information and services that we provide to members of the program.

Our program and API is created based on the success of eBay’s API. We are striving to make our API as similar as possible to the eBay API, with the advantage that developers having developed tools or applications for either platform, should find it easy to port them to the other platform.

Technical overview

The Tradera Service API is divided into two parts: The Public Service and the Restricted Service. The Public Service contains methods that correspond to the information found on the site when you are not logged in, while the Restricted Service is used for actions that require user authorization, like adding an item, or getting the address of a buyer.

All methods are available as SOAP calls and most are also available using regular GET/POST. See the API documentation for more information.
