Compatible Application Check

Complete a Compatible Application Check to request an increase in your API Call Limits.

You will need to complete the compatible application check process, if you anticipate needing API call limits higher the default number of calls per day (24 hour period, starting midnight Pacific time).

After you join the eBay Developers Program and get your application keys, you can start using eBay APIs immediately. The default call limits on the eBay APIs allow you to test and explore the API capabilities. Many applications are able to perform all capabilities using the default limits. If you need higher call limits, you can complete our free Compatible Application Check, to verify that your application is adhering to eBay's API License Agreement, and that you've made the most efficient use of the APIs you've implemented.

The app check is a free service that the eBay Developers Program provides to its members. To help speed you through the process, please use the Checklist for Going Live provided below. It tells you what you'll need to do before applying. Much of this will be obvious but some of it isn't, so please be sure to make full use of the Checklist for Going Live, before submitting your Compatible Application request.

See the API Call Limits page for the call limits associated with each eBay API.

Checklist for Going Live

  • Application Readiness: You will need a working application that we can test to ensure it complies with the requirements for the Compatible Application Check. Be sure to follow the guidelines below as you create your application.
  • API license and eBay Polices: Check that your application complies with:
    • The eBay API License Agreement.
      This includes, but is not limited to:
      • Collecting statistical or other information related to specific eBay users, groups of eBay users, or or types of eBay users
      • Deriving conversion, completion, or success rates, unless the information is specific to the user logged into your application and only to be shown to that user.
      • Estimating or displaying reserve auction prices of other users
      • Deriving sales or activity rates for listings with specific features or enhancements, unless the information is specific to the listings created by the user logged into your application and only for that user's view.
      • Displaying a user's private profile or detailed feedback information, unless the information is specific to the user logged into your application and only to be shown to that user
      • Collecting statistical data about eBay.
      • Deriving average selling price or gross merchandise value for any eBay category.
    • The eBay API Logo Usage Requirements (When you can use the eBay logo in your application.)
    • eBay site policies
    • The consumer protection and privacy laws and eBay User Agreement. For more information and practical tips, see Display Listing and Privacy Policy Help Page.
  • Technical Best Practices: Ensure that your application:
    • Follows the OWASP secure coding principles . For further information on web application vulnerabilities and how to protect against them go to the OWASP "Top Ten"
    • Uses the UTF-8 encoding scheme (not ISO-8859-1). For more detail see the article Working with UTF-8".
    • Uses the latest versions of the APIs before applying. Go to the API documentation and view the Release Notes for the APIs you're using to find the latest versions.
    • Handles errors gracefully and implements retries correctly. In particular, implement retries for a maximum of two times for infrastructure errors.
    • Limits the volume of data returned by asking only for the required amount of information and don't make calls more frequently than necessary.
    • Don't collect eBay Username and Password from your customers, instead implement support to retrieve OAuth tokens (eBay's earlier Auth & Auth tokens are also still available for older APIs). For Shopping API, Finding API and Merchandising API you do not need any username / password or user tokens.
  • Don't use more than 18 simultaneous threads to make API calls.
  • If you have a web application, don't put eBay web pages served by eBay servers in an iFrame.
