Insufficient permissions to fulfill the request

[seattlegoodwill]

I am trying to access Inverntory Items API but it is showing as insufficient permissions for getInventoryItems. It is showing this message in API explorer. Also I need to access this endpoint in Logic Apps.

Hello @seattlegoodwill,

The error message you're encountering typically occurs when an incorrect token is used to make a request. The getInventoryItems API requires a User token, which is generated through the Authorization Code Grant flow. Please ensure you are using the correct token for this API, as using an Application token or a token generated through the Client Credentials Grant flow will result in an error.

For detailed guidance on generating a User token using the Authorization Code Grant flow, please visit: https://developer.ebay.com/api-docs/static/oauth-authorization-code-grant.html 

Best Regards,
eBay Developer Support

I have explained the process here https://github.com/CMS365-PTY-LTD/EbaySharp?tab=readme-ov-file#access-and-security 

You can create an API which you can call from logic app and that API will call eBay directly Or If you prefer to use package I created.
