i have read that in in able to test IPN in localhost magento site ,i can use Advance Rest API in google chrome ,now i downloaded already the app and test some values, but it showed The response was Empty..
how to test it correctly? am i doing the right thing there in the picture above? thank you,
You cannot test IPN on your localhost, as IPN is all about PayPal's server initiating a server-side POST to a URL you define.
As a result, your IPN script must be accessible by the outside world (or you can use a tunnel such as ngrok.me/localtunnel.me)
You can test on localhost using ngrok :- https://ngrok.com/
Simply run ngrok locally then paste test url that ngrok gives you (something like http://1bc7d09d.ngrok.com/)
It provides a tunnel to your localhost.

I am running a ruby Sinatra server on my development machine with ngrok.
I have verified that the accessing the publicly exposed url through ngrok does get routed to the ruby server and the correct response is returned.
I also used apitester.com to verify that the exposed url is accessible from the internet and the correct response is returned.
When I attempt to execute using the Alexa Simulator through the alexa developer console I only get "I am unable to reach the requested skill". I get the same response using a physical echo also.
I have double checked the endpoint configuration of the developer console and everything looks like ok to me.
I am using https for the endpoint with the "My development endpoint is a sub-domain of a domain that has a wildcard certificate" as the SSL certificate type.
Using the JSON request that is generated when attempting to use the Alexa Simultor does successfully send the request to my Sinatra server and the appropriate response is returned. This eliminated my concern that this was related to the sinatra/ngrok configuration, but it continues to fail when entering text (or speaking) into the simulator.
This is my first attempt at creating an Alexa skill, so I may be overlooking something obvious.
Does anyone have any suggestions?

I had set the default and North America endpoint urls containing the same URL.
Removing the optional North America endpoint url solved the problem for me.
I'm starting with Messenger Platform API. I want to make simple Messenger Chatbot. Here is tutorial I follow.
As you see, to start I need to set up webhook (step 2). So basically: web server that provides some REST API and posts some data back. The problem is: facebook requires me to provide some real, existing app URL that works currently in internet. So, do I need to upload my code to server each time I change something? Can I somehow test it locally (on my localhost)? How can I test behavior of my bot?
There's a few services you can use to expose your webserver running on localhost to the public. Two options are localtunnel and ngrok.
An example (from localtunnel's quickstart) of how you might do this, given that your webserver is running at http://localhost:8000/ would look like this:
Install localtunnel from npm:
npm install -g localtunnel
Request a tunnel to your local server:
lt --port 8000
This will generate a link, of the form https://foo.localtunnel.me you can use to access your localhost from the web. One nice feature is that you automatically get https so Facebook won't give you a 'SSL certificate problem' error. Localtunnel or ngrok are also nice for sharing work running locally with others.
Note that the localtunnel url is only valid as long as the connection lives, so you will have to update the url Facebook has if the connection ends.
I created a library that tries to solve this exact problem! With fb-local-chat-bot you can easily test your bot offline. The library also makes testing much more simple. If you're interested, definitely check it out
https://github.com/spchuang/fb-local-chat-bot
Demo:
you may use ngrok to test the messenger bot in localhost. You may download it at:
https://ngrok.com/download
on executing ngrok, it will generate secure link that can be used as a end point in webhook.
You can also check the detailed status of each request and response of ngrok through
http://localhost:4040/inspect/http
Later, once you are done, you may deploy your code to secure server.
You can find more info as to how to build a basic chat bot on the link below:

You can deploy your backend services on heroku free of cost. It provide public DNS with RSA.
If you can't use ngrok for some reason (like routing webhook to multiples dev machines). please try this emulator i have created for developing / debugging webhooks locally. this provides emulation of send api and a messenger ui
I have created an emulator for send api and messenger which i use for debugging web hooks locally
https://github.com/SonOfSardaar/facebook-send-api-emulator
I also came across this (i have not tried this one yet but looks good)
https://learn.microsoft.com/en-us/bot-framework/debug-bots-emulator
Good evening, just saw that Facebook released his messenger bot toolkit and i immediately jumped right into it to learn more about it and maybe try to do my own.
My problem is that i don't have a https website running and it requires a https valid url. I tried to use my local web-server that has a certificate but it doesn't work.
My question is if this is possible to be done using a localhost url at all.
Thank you in advance
Actually this is possible with localhost. Use ngrok. It allows you to open localhost to the public web, over http or https. This should only be used for testing however.
If you want to test webhooks on your local environment, I would try ultrahook.com, you can get an API Key for free and the tool creates a tunnel from a public URL to your computer. This is from their FAQs page:
You download and run the UltraHook client on your computer. It
connects to UltraHook servers in the cloud and creates a tunnel from a
public endpoint on our servers to your computer. Any HTTP POST
requests sent to the public end point will be sent through the tunnel
an delivered to a private endpoint accessible from your computer.
I have used it to test webhooks from different providers (like payment gateways). In your computer, you can run something like:
ultrahook <subdomain> http://localhost:8000/webhook/
and then configure the webhook URL in your external service to something like <subdomain>.ultrahook.com
My question is if this is possible to be done using a localhost url at all.
No, of course it isn’t – because what such a “callback” actually means, is that Facebook makes a request to your server – and that is hardly possible with localhost.
A valid SSL certificate for your website is easy to get for free these days, via LetsEncrypt. And even if that is not available on your server, there’s still StartSSL, that provide basic certificates for free. All you need is a server you can install them on, or upload them to, or whatever mechanism your hoster provides for it. (And if they don’t provide any, then it might be time to switch.)
Iv been working to intergrate the paypal REST API into a web application, its now time to change from the sandbox endpoint to the live endpoint, but iv hit a snag, it seems like the live endpoints have dropped from the face of the earth. the sandbox environement works, api.sandbox.paypal.com and i can reach it via ping and so on,
but not api.paypal.com which is the live endpoint according to developer.paypal.com/webapps/developer/applications i can not even ping the live server, both from my local development environment and a cloud server instance. im i doing something wrong?
Edit:
solved, see comment
In order to publish real-time updates to my app, Facebook needs needs to perform a post request to my server.
Problem is, my server is my home computer and not publicly addressable from the internet. Bringing a server live to implement this sounds like it could be a pain... can't attach debugger, fiddler etc....
So what's the best way to test the Http Endpoint? Integration tests that simulate the Facebook server? Fiddling with firewalls/NAT to try and get Facebook talking to my home computer?
Any ideas?
You can use ngrok - https://ngrok.com/ - free (pay-what-you-can) service that does exactly what you need. Localtunnel service is down and the developers also recommend ngrok.
In the past, I've used LocalTunnel to do this. It's a nice wrapper around an SSH tunnel and it effectively assigns you a subdomain at localtunnel.com pointing to a port on your localhost.
So basically, when you run it it will spit back an externally accessible sub domain name like xyz.localtunnel.com who's port 80 will point a port you specify on your local box.
You can find it at: http://progrium.com/localtunnel/
It's really great for testing various pubsubhubbub subscription feeds (like Facebook's).
OK! I think NAT should be the best bet and I don't see a reason for it not to work. You should try it out.
It was actually pretty easy - Logged into my home router, set up port forwarding on port 80 to the local IP of my computer, put an exception in windows firewall for port 80. and then navigate to my public IP address in the browser.
Implement the receiver samples at: https://github.com/facebook/real-time/tree/master/samples
The only answer is to get a webserver that is publicly accessible for real-time updates to be able to call back to.
There's lots of free webhosts that allow server-side scripting. And there's lots of paid for webhosts out there too. Stackoverflow is really not the place to get leads on where/when/why/howmuch for web hosting.
No you can't use ngrok only to simulate facebook realtime update since you must make a call to facebook servers with your ngrok adress to validate it (tell me if you find out how to do this :p ).
I use an openshift server to receive facebook realtime and then post evry json data received from facebook to my ngrok adress. So the process is
set up an openshift server to receive facebook notifications
Facebook sends notifications to your openshift
your openshift sends datas (as received) to your ngrok adress
And if you must receive facebook notifications on a local website (like www.website.dev/fb-notifications/) then create a script in your localhost folder which receives openshift posts (let's call it tunelscript.php). the process will be
set up an openshift server to receive facebook notifications
Facebook sends notifications to your openshift
your openshift sends datas (as received) to your tunel script via your ngrok adress (perso.ngrok.com/tunelscript.php)
Relay datas from your tunelscript to your local website (tunelscript.php => www.website.dev/fb-notifications/)
That's Tuneling B-)
