How do I make an API call to create a fullfillment policy?
I need to create a Fulfillment Policy, there is a guide on how to do it, but I have no idea how to make an API call. I looked for a guide online but I found no explanation on how to do it. Someone suggested downloading the "Postman" extension on Chrome, so I did, but I still don't know how to make the call correctly. On ebay's page it says that the URI doesn't need parameters, so I left it as it is, I also set the header with the authorization it needs (Via the Postman extension). I don't know how to set the OAuth scope and the Request Payload. Where do I type them in?
