We have had the same privacy policy URL for our facebook app since ~2013. This morning, facebook sent over a "warning" email that our application didn't have a valid privacy policy URL. I searched everywhere and could not find a contact email for their dev team.
I found in another post, Facebook privacy policy error to try and use Facebook's debug tool to validate the URL. When I add the URL and submit it, it shows "206" (partial content). The URL itself links back to a PDF file, but again, this was never a problem in the last 5 years or so, the URL hasn't changed (and the app hasn't been updated), but now there seems to be a problem. Can anyone help me figure out how to get this addressed? or how to get into contact with FB dev support, directly?
At this moment I'm working with the Facebook API; I Need to fill in a Privacy Policy, so I did. However, after some research I discovered that the HTTP Response code will always be 503, But I can't find out why. The page is there, and when visiting it in a Browser it works, with no problem at all. Running a check, shows me that the page returns a 503 to facebook and any other request (For example. https://httpstatus.io/).
I use cloudflare, nothing more. Why am I getting a 503 Response, but the page is just working fine?
It is possible to have 503 only when robot is visiting the page. Try to simulate Facebook User Agent from your browser or rest client.
You can check Facebook user agents on developers facebook page:
https://developers.facebook.com/docs/sharing/webmasters/crawler
Cloudflare could be the cause of your problem, because it blocks bad robots (Facebook should be good robot). Try to disable it and see if it works. If this is the problem, you need to contact Cloudflare support.
Im trying to setup and webhook for facebook leads, i've followed the tutorial that is given. Everything works fine and all the verification steps through the Graph explorer are "OK". My endpoints seams to live and working.
But when i try the Lead Ads Testing Tool and make an request to send the form i get the status "404 rejected"
I have verified that the callback url is correct, both via the Graph explorer and the webinterface on developer.facebook.com under the tab "Webhooks"
I have logs on the server so i can see all types of requests done to the url, empty or not and i don't even get an request. I've tried to rule out every possible "auth" problems.
So i'm stuck guys, what is missing? What i'am doing wrong?
I'm totally stuck and Facebook support doesn't respond.
I'm promoting an app from a Facebook page. The link to my web page on set up worked fine.
Couple weeks ago I noticed a security warning users were getting when they clicked a link to my site from Facebook.
The Google tells me this warning is usually issued by site suspected of redirecting or calling external javascript that looks suspicious.
I ran the URL through the URL Debugger.
There is a 301 redirect there but it's not flagged as an issue that needs fixing, only one that impacts the inability to find or download my og:image file but that's not flagged as a must fix either and the URL Debugger actually displays the image -- so it does find it.
I've localized all external Javascript calls, I've inspected the .htaccess for 301 redirects and removed all ReWrite engine instructions.
I thought maybe Facebook was tripping over my URL parameters -- my Facebook page linked to http://www.brian-fitzgerald.net/i-ching/?fbp -- so I tried to change it in the setup of my page. I can't. Any formulation of the URL is called invalid:
So I have a Facebook URL debugger that basically gives the site a near-clean bill of health.
A warning to users that they shouldn't click unless it's a trusted site.
And a content mangagment system that says the URL is completely invalid.
In short, WTF?
I can't see what Facebook is tripping over. Can anyone else?
I'm trying to get the code to use with /oauth/access_token to get the access_token for a facebook app. From what I've read (here and in the facebook dev docs about access token), I have to make a request at that adress :
http://www.facebook.com/dialog/oauth/?client_id=269256053176066&redirect_uri=https%3A%2F%2Fwww.outils.ch%2Ffacebook%2Fgroupemutuel%2Fcanevas%2Fadvices%2F&scope=publish_stream,manage_pages
And it should give me back as a get parameter the code to use to generate the access_token. This is where I'm stuck, it redirect me to the facebook app page, but without any code. I've been on this since yesterday and can't figure what I'm missing and dont find any similar post.
Well I finally find out where was the problem, the page was redirecting automatically to the facebook app page (whitout the code). I was able to find the code with chrome console in network tab.
