eBay API Connection

Authorize eBay access for a Next-Cart migration service when eBay API setup is shown for your selected platform.

A valid eBay API connection gives Next-Cart the authorized platform access required by the selected migration path.

For eBay, the setup usually uses an authorization flow. Next-Cart provides or displays the authorization path, then eBay asks you to sign in and grant access. After authorization succeeds, Next-Cart receives or shows the connection value needed for setup.

Use this guide when:

  • eBay is the Source Platform or Target Platform in your selected migration path;
  • Next-Cart shows eBay API setup;
  • Next-Cart provides an eBay authorization link or asks you to complete eBay authorization.

Before you begin, confirm that:
