HTTP POST Google Cloud Functions NodeJS

How do I write a Google Cloud Function that will receive a HTTP request and then send a HTTP POST request to a different endpoint?

For example,

By far I have tried sending HTTP POST with node-webhooks, request & restler modules but none of them seem to work. Is it because these modules are used in conjunction with exports.test ?

My question is related to this question but the answers didn't help me.

The data being sent to endpoint is in json & Content-type: application/json.

var request = require('request'); //also tried for node-webhook, restler modules

exports.test = function(req, res) {
 //processing of received json data from source A. 

function sendToEndpoint(processed_data) {

  let abc = processed_data;   //send processed data to source B{
      uri: '',
      headers: {'Content-Type': 'application/json'},
      body: JSON.stringify(abc)


As @RenaudTarnec mentioned in the comments the problem was that my billing account was not configured.

Google doesn't allow outbound requests to external servers without valid billing info so as to prevent any malicious activity.

After configuring a billing account I was able to make outbound requests and all the node-modules mentioned in the question worked.
