We are trying to use the MWS API GetEligibleShippingServices but we got this response:
Array (  =>  =>  =>  => Sender  => ForbiddenRequestBlocked  => The request was blocked because it is forbidden.  =>  => 4b9db405-fca9-4ee5-ac82-07a43645f2d7  =>  => )
I think that is a problem of PII permissions.
Someone could help us to activate this option?
I wish you a nice day
