If you are not yet familiar with GraphQL and GraphiQL it is highly recommended to review those pages at first.
FeedId:StopId formatgtfsId (note that field gtfsId also contains the feed ID)Note: For more details about the query types related to stops you can use the Documentation Explorer provided in GraphiQL.
Note: If the examples provided with an ID do not return what is expected then the ID in question may not be in use any more and you should try again with an existing ID.
zoneId tells which zone the stop is located in{
  stops {
    gtfsId
    name
    lat
    lon
    zoneId
  }
}{
  stop(id: "HSL:1140447") {
    name
    wheelchairBoarding
  }
}{
  stop(id: "HSL:1140447") {
    gtfsId
    name
    lat
    lon
    patterns {
      code
      directionId
      headsign
      route {
        gtfsId
        shortName
        longName
        mode
      }
    }
  }
}name can be a part of the stop name (e.g. "hertton" or "rautatientori").{
  stops(name: "hertton") {
    gtfsId
    name
    code
    lat
    lon
  }
}Station is a location, which contains stops
{
  stations {
    gtfsId
    name
    lat
    lon
    stops {
      gtfsId
      name
      code
      platformCode
    }
  }
}{
  stations(name: "pasila") {
    gtfsId
    name
    lat
    lon
    stops {
      gtfsId
      name
      code
      platformCode
    }
  }
}first is not used in the query, all results will be on one page.radius is the maximum walking distance along streets and paths to the stop{
  stopsByRadius(lat:60.199, lon:24.938, radius:500) {
    edges {
      node {
        stop {
          gtfsId
          name
        }
        distance
      }
    }
  }
}serviceDay in the response is Unix timestamp (local timezone) of the departure dateValues scheduledArrival, realtimeArrival, scheduledDeparture and realtimeDeparture in the response are seconds since midnight of the departure date
serviceDay{
  stop(id: "HSL:1140447") {
    name
      stoptimesWithoutPatterns {
      scheduledArrival
      realtimeArrival
      arrivalDelay
      scheduledDeparture
      realtimeDeparture
      departureDelay
      realtime
      realtimeState
      serviceDay
      headsign
    }
  }
}Use argument startTime in stoptimes query
startTime is Unix timestamp (UTC timezone) in seconds{
  stop(id: "HSL:1140447") {
    name
    stoptimesWithoutPatterns(startTime: 1528633800) {
      scheduledArrival
      realtimeArrival
      arrivalDelay
      scheduledDeparture
      realtimeDeparture
      departureDelay
      realtime
      realtimeState
      serviceDay
      headsign
    }
  }
}startTime.platformCode contains the platform code used by the vehicle{
  station(id: "HSL:1000202") {
    name
    stoptimesWithoutPatterns(numberOfDepartures: 10) {
      stop {
        platformCode
      }
      serviceDay
      scheduledArrival
      scheduledDeparture
      trip {
        route {
          shortName
        }
      }
      headsign
    }
  }
}Querying nearest departure rows returns only one stop per pattern
{
  nearest(lat: 60.19915, lon: 24.94089, maxDistance: 500, filterByPlaceTypes: DEPARTURE_ROW) {
    edges {
      node {
        place {
          ...on DepartureRow {
            stop {
              lat
              lon
              name
            }
            stoptimes {
              serviceDay
              scheduledDeparture
              realtimeDeparture
              trip {
                route {
                  shortName
                  longName

          }
        }
        distance
