Hi i trying to understand how i do a POST request. I use the "http request" and changing "GET" to "POST" and typing in the url https://api.trafikinfo.trafikverket.se/v2/data.json
but where do i put my question?
Is look like this

<REQUEST>
      <LOGIN authenticationkey="MYkey" />
      <QUERY objecttype="TrainAnnouncement" schemaversion="1.8" orderby="AdvertisedTimeAtLocation">
            <FILTER>
                  <AND>
                        <EQ name="ActivityType" value="Avgang" />
                        <EQ name="LocationSignature" value="Nkv" />
                        <OR>
                              <AND>
                                  
                                    <GT name="AdvertisedTimeAtLocation" value="$dateadd(-00:15:00)" />
                                    <LT name="AdvertisedTimeAtLocation" value="$dateadd(14:00:00)" />
                              </AND>
                              <AND>
                                    <LT name="AdvertisedTimeAtLocation" value="$dateadd(00:30:00)" />
                                    <GT name="EstimatedTimeAtLocation" value="$dateadd(-00:15:00)" />
                              </AND>
                        </OR>
                  </AND>
            </FILTER>
            <INCLUDE>AdvertisedTrainIdent</INCLUDE>
            <INCLUDE>AdvertisedTimeAtLocation</INCLUDE>
            <INCLUDE>TrackAtLocation</INCLUDE>
            <INCLUDE>ToLocation</INCLUDE>
      </QUERY>
</REQUEST>

In msg.payload this will be the body for your request.
You can use a Template node for this

Example Flow:

Note: i have also added Content-Type: application/xml in the http-request that seems to be needed for the server to know what your are sending.
Also changed the http-request Return to be parsed as JS object since its JSON

That works perfect, thanks for the help!
