Synchronization issue - error message 400

When I try to get data on orders, an error 400 comes out although the same request through postman produces the correct data.
And the error report we get is empty

Has somebody already faced such an issue ?
Has amazon a dedicated technical support for such problem ?

Thank you.

Regarding the error 400, it typically indicates a bad request or invalid parameters. Since you mentioned that the same request through Postman yields the correct data, it suggests that the issue might lie within the code or configuration of your system making the request. It’s essential to ensure that you’re using the correct API endpoints, headers, and parameters when making requests to retrieve order data.
