REST API v7: cannot create a new project

Hi everybody,

I'm trying to create a blank Project using REST API v7, but the best result I had was "401 Unauthorized" (I'm using Postman to test). 

Since all the other activities (creating test cases, test sets, etc) I've performed via APIs were successful, my guess is there is something wrong with permissions associated with the user account I'm using to perform the operation (Program Owner).
 

Here some details:

- API: SpiraTeam: REST Web Service

- POST: passing existing project ID, username and RSS/API-key
- request body:

{"ProjectId":null,

"ProjectTemplateId":null,

"ProjectGroupId":17,

"Name":"MyDesperateAttempt",

"Description":null,

"Website":null,

"CreationDate":"0001-01-01T00:00:00",

"Active":true,

"WorkingHours":0,

"WorkingDays":0,

"NonWorkingHours":0,

"StartDate":null,

"EndDate":null,

"PercentComplete":0,

"RequirementCount":0,

"WorkspaceTypeId":0,

"Guid":null,

"LastUpdatedDate":null,

"ArtifactTypeId":0,

"ConcurrencyGuid":null,

"CustomProperties":null}

Am I missing something or doing something wrong?

Any suggestion welcome.
