Running a Connector Dataset Programmatically - Full Authorization Required

Hi,

I have a dataset created using the Amazon Redshfit Unload connector, created via the Domo Web Interface.

I would like to call this programmatically via a POST request to the api.

I am making a post request to: my Domo instance using OAuth 2.0.

And I am recieving this response:

{
    "status": 401,
    "statusReason": "Unauthorized",
    "path": "/api/data/v1/streams/684/executions",
    "message": "Full authentication is required to access this resource",
    "toe": ""
}

Is there a way to do this?

Thanks.
