I'm trying to develop an application that takes a set number of listings, and adds them to a member's cart. I have the listing functionality working properly, but when trying to add those items to the cart, I run into this :
HTTP/1.1 404 Not Found Verify the endpoint URL and your API access.
The endpoint is currently set to https://api.ebay.com/buy/order/v1/checkout_session/initiate
I might be missing something obvious, but if not, how do I gain access to the checkout api so I can put items into a user's cart?
