Set up a proxy server on your backend that will act as an intermediary between your frontend and the eBay API. The proxy server can forward requests to eBay, receive the response, and send it back to the frontend. This bypasses CORS restrictions because the browser considers requests to your server as same-origin.
By following these steps and integrating the eBay API on your backend, you can overcome CORS restrictions and use eBay's data and functionality in your application. Make sure to consult eBay's developer documentation for specific details on how to authenticate, make requests, and handle responses from their API.
