How to fire POST request using inline editor in dialogflow?

Question

Code:

var rp = require('request-promise');
var options = {
                method: 'POST',
                uri: 'http://c663fe13.ngrok.io/ap/lighton',
                body: {"color": 'white'},
                json: true // Automatically stringifies the body to JSON
            };

            rp(options)
                .then(function (parsedBody) {
                    // POST succeeded...+
                    console.log("parsedBody", parsedBody);
                })
                .catch(function (err) {
                    // POST failed...
                    console.log("err", err);
                });

but this gives me the following error:

{ RequestError: Error: getaddrinfo EAI_AGAIN c663fe13.ngrok.io:80 at new RequestError (/srv/node_modules/request-promise-core/lib/errors.js:14:15) at Request.plumbing.callback (/srv/node_modules/request-promise-core/lib/plumbing.js:87:29) at Request.RP$callback [as _callback] (/srv/node_modules/request-promise-core/lib/plumbing.js:46:31)

. . .

name: 'RequestError', message: 'Error: getaddrinfo EAI_AGAIN c663fe13.ngrok.io:80',
cause: { Error: getaddrinfo EAI_AGAIN c663fe13.ngrok.io:80 at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:67:26) errno: 'EAI_AGAIN', code: 'EAI_AGAIN', syscall: 'getaddrinfo', hostname: 'c663fe13.ngrok.io', host: 'c663fe13.ngrok.io', port: 80 },

I trie to call that API with postman and it's working fine.

If you are using a free account you will not be able to hit any 3rd party services from Firebase cloud functions. It would be better if you write down your own webhook code and using fulfillment integrate that webhook with your Dialogflow agent if you are going to use the free account.

UPDATE Check out the code snippets I have shared here. You can use that to integrate ExpressJS and then add your POST code and host it locally. Expose the local server using ngrok and then put that URL in fulfillment.

Okay, and for the solution, do you have any example on that? – Harsh Patel May 03 '19 at 09:10
should I use all 3 things or just Express JS with Dialogflow is enough? – Harsh Patel May 03 '19 at 09:21
Depends on your use. If using Action on Google you will need the second one. If you are new to NodeJS then please go through some online tutorials first for better understanding. – Abhinav Tyagi May 03 '19 at 09:22
Yes, I am using Action on Google. I tried inline fulfillment but as you know It can't be done because of a free account. thanks for the node suggestion but I have done node very well bro. just confusing with dialogflow and action-on-google. – Harsh Patel May 03 '19 at 09:28
then just use the code snippet and enjoy Google Assistant ;) – Abhinav Tyagi May 03 '19 at 09:30
Sure, I'll try. Thanks for the help. – Harsh Patel May 03 '19 at 09:30
I am not able to use server tunneled by ngrok because it was running on HTTP and while adding that URL to Fulfillment it show **You can use the only https:// in fulfillment URL when "Google Assistant" integration enabled** – Harsh Patel May 03 '19 at 09:42

ngrok gives https option. I am using it – Abhinav Tyagi May 03 '19 at 09:43
