Hello, 

The api works pretty well when executing trackDemoBoards without problems.

But when trying to update a demoboard with a the OpportunityData, it always respond 401 - unauthorized_error. 

→ User have the admin permissions, it was the user that have created the demoboard

→ the api documentation is not very clear how to build the request: sign as no description, and the entityData in items as not example or schema in the openapi or postman collection

{
    "auth": {
        "api_key": "{{key}}",
        "api_secret": "{{Secret}}",
        "user_email": "{{user}}",
        "source_name": "Postman"
    },
    "request": {
        "sign": "f0b52176-0c78-4552-9519-d7af25b17a5e",
        "updatedEntities": {
            "entityType": "OPPORTUNITY",
            "entityAction": "UPDATE",
            "items":  
                {
                    "entityId": "test"
                }
            ]
        }
    }
}
