The issueRefund documentation states that the client credentials grant flow is required. This seems odd to me because every other endpoint I've consumed uses authorization code grant flow. When I check my key set, I only see '
https://api.ebay.com/oauth/api_scope/sell.fulfillment' available for authorization code grant type. The only scope I have available for client credential grant type is '
https://api.ebay.com/oauth/api_scope'. As expected, when I attempt to mint a client credential token for the fulfillment scope, I receive invalid_scope error. Desperately trying to automate refunds for managed payments. Thanks, Shaun
