@andrewbrazzatti Did you intend to add another route for listDatastreams, or change the existing route from put to get?

Also, doesn't the route for getDataStream above need the datastreamId?

'get /:branding/:portal/api/records/datastreams/:oid/:datastreamId': {
    controller: 'webservice/RecordController',
    action: 'getDataStream',
    csrf: false
  },
