this

you're missing accept: */* header. also, json.stringify not application/x-www-form-urlencoded. here working code build based on:

var request = require('request'); var endpoint = 'www.sandbox.paypal.com'; var options = {   form: {     cmd: '_notify-synch',     tx: tx,     at: auth   },   headers: {     accept: '*/*'   } }; request.post('https://' + endpoint + '/cgi-bin/webscr', options, function(e, r, body) {   return console.log(body); });
