  • New Feature: The Inventory Mapping API helps you turn your existing product data into high-quality listings with AI-powered recommendations. Learn more here.
  • Important Update: eBay's API integrations will be modified to address data handling requirements for select developers. Usernames will be replaced with immutable user IDs, and financial data will be protected for certain users. Learn more here.
  • Action required: From early May, API users must include standardized condition details when creating or updating listings. Update your integration to stay compliant. Learn more here.

Note: The Client Registration API is not intended for use by developers who have previously registered for a Developer Account on the eBay platform.
The Client Registration API provides Dynamic Client Registration for regulated Third Party Providers (TPPs) who are, or will be, engaged in financial transactions on behalf of individuals domiciled in the EU/UK. This is required by the EU's Second Payment Services Directive (PSD2) which requires all regulated Account Servicing Payment Service Providers (ASPSPs) to provide secure APIs to access account and payment services on behalf of account holders.

A successful registration response returns a HTTP 201 Created status code with a JSON payload [RFC7519] that includes registration information.
