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

When we run request to the website with Cloudflare ON from python request module on local machine it works fine and return status 200.
If however exactly the same code executed from Google Cloud Run instance it returns status 522.
What we've done so far:
We went through help article about error 522 in Cloudflare documentation with our webserver provider and they confirmed we are all good on their side.
We stopped the Proxy from Cloudflare for the domain/ip.
This worked fine and we were able to run requests from the Google Cloud Run. All the requests went through.
What is the best way to set up Cloudflare so that proxy is ON and our requests are going through to the webserver?
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 am developing a web service using REST API. This REST API is running on port 6443 for HTTPS. Client is going to be a Single page application running on port 443 for HTTPS on same machine. The problem I am facing is:
While I hit the url say: https://mymachine.com/new_ui I get certificate exception for an invalid certificate because I use a self signed one, so mymachine.com:443 gets added to server exception. But still requests doen't go to REST API as they are running on https://mymachine.com:6443/restservice. If I manually add mymachine.com:6443 to server exception on firefox it works but it will not be the case in production for customers.
Some options that I thought are:
1. Give another pop up and ask to add REST server on port 6443 exception too.But this doesn't look proper as why an end user should accept the cerf for same domain twice. Also REST api server port can change.
Can we programmatically add exception for domain and both the ports in one shot? Ofcourse with the consent of the user. 3. Use a reverse proxy. But then its going to have memory footprint on our system. Also it will be time consuming.
Please suggest some options. How do I deal with it. Thank you
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.)
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-)
