am able to access basic order and customer data through the Fulfillment API, but I still cannot retrieve full financial details (such as transaction fees, promoted listing fees, regulatory or processing fees) for each sale via the Finance API.I understand that this requires sell.finances API scope, and possibly Signature Key/digital signing, which appear to be unavailable or unconfigurable from my developer account interface.Specifically:My app’s current OAuth scopes include sell.account.readonly and sell.fulfillment.readonly only.Attempts to add sell.finances scope lead to authorization or scope errors (including "Missing x-ebay-signature-key header" and “requested scope is invalid/unknown/malformed”).My developer portal does not show any option to generate or manage signature keys, nor is there a “Signed Fetch” setting, as referenced in documentation and community help.Why this matters:The ability to pull actual eBay sales fees at the transaction level is essential for the accounting automation functionality. Without access to these endpoints and features, the app cannot deliver the core value I discussed with you at the event.Request:Could you please connect me to a team or specialist who can:Enable or advise on how to enable sell.finances scope for my appEnable digital signature key provisioning so I can comply with the latest API security requirementsHelp resolve these account-level barriers so I can complete and commercialize my integrationI am reaching out because you kindly offered your assistance in case I faced ongoing integration challenges, and I have exhausted all other available channels.Many thanks in advance for any support or direction you can provide.
