You don t want multipart  but a  plain  POST request  with Content-Type  application json  instead  Here is all you need   var request   require  request     var requestData       request        slice                    origin   ZRH           destination   DUS           date   2014-12-02                     passengers          adultCount  1        infantInLapCount  0        infantInSeatCount  0        childCount  0        seniorCount  0            solutions  2      refundable  false         request  https   www googleapis com qpxExpress v1 trips search key myApiKey             json  true  body  requestData            function err  res  body          body  is a js object if request was successful

I feel   var x   request post          uri  config uri         json  reqData           Defining like this will be the effective way of writing your code  And application json should be automatically added  There is no need to specifically declare it

I worked on this for too long   The answer that helped me was at  send Content-Type  application json post with node js  Which uses the following format   request       url  url      method   POST       headers             content-type    application json                  json  requestData     body  JSON stringify requestData         function  error  resp  body

According to doc   https   github com request request  The example is     multipart          chunked  false        data                         content-type    application json              body  JSON stringify  foo   bar    attachments    message txt    follows  true  length  18   content type    text plain                                  I think you send an object where a string is expected  replace   body  requestData   by   body  JSON stringify requestData

I think the following should work      fire request request       url  url      method   POST       json  requestData          In this case  the Content-type  application json header is automatically added

Example   var request   require  request     var url    http   localhost 3000    var requestData                 var data         url  url      json  true      body  JSON stringify requestData     request post data  function error  httpResponse  body       console log body         As inserting json  true option   sets body to JSON representation of value and adds  Content-type    application json  header  Additionally  parses the response body as JSON  LINK
