How to call webhook Rest URl of localhost with Dialog Flow?

Question

I am trying to call my Rest webhook from dialog flow console. I know it is feasible with deployment to any public ip.

But how to test the same without hosting the webhook to any public IP, and test it via localhost:8080/webhook?

you can use ngrok tool for this – Manjeet Thakur Dec 15 '17 at 06:19 — Manjeet Thakur, Dec 15 '17 at 06:19

You can't do this - Dialogflow needs a public HTTPS server to access.

Fortunately, you can use a tool such as ngrok, which will create a tunnel between your machine and a public host name/address. You run ngrok on your localhost and tell it what local port your server is on. It will display a hostname that you can plug into Dialogflow. As long as you keep ngrok running locally, you'll have that address.

It depends exactly what you mean by "debug", but yes. – Prisoner Feb 13 '19 at 10:19
Hitting the breakpoints of the application, in my case it is not – Sana Ahmed Feb 14 '19 at 04:37
@Sana- I suggest you open a new StackOverflow question, providing as many details as possible explaining what you're trying to do (including code and the environment you're using), how you're doing it, and what isn't working. – Prisoner Feb 14 '19 at 09:15
Thanks, this is what I was looking for. – Codigo Morsa Apr 11 '21 at 08:56

Run your local host server as you do.

Then download the following utility.

https://ngrok.com/download

Then unzip it and you will get a ngrok binary.

Then run, ngrok http portnu

here port number is the one where your local webserver is listening.

On running the above command, ngrok will provide a http as well as a https public url. Use that public url as your fulfillment logic on dialog flow console. And now you have a local webhook running.

You can use Webhook Relay (https://webhookrelay.com) to create webhook forwarding tunnels:

$ relay forward -b webhook-demo http://localhost:8080/webhook
Forwarding:
https://my.webhookrelay.com/v1/webhooks/5e722a5e-f3d2-4hqec-9e9f-79f1158e4b10 -> http://localhost:8080/webhook
starting webhook relay agent..

Endpoints are permanent (until you delete them) and it is also possible to inspect webhook body, retry them or fan-out webhooks to more than one destination.
