How to post to a users wall as the App - facebook-graph-api

I have build a Facebook-app that needs to post to the users wall in certain situations. I've come a long way in doing this: it works perfectly, even when the user is not logged in. However, I need to post to the user's wall on behalf of the app, not the user himself. The reason is that posting as the user will not trigger a notification.
Does anybody know how to do this?

This is not possible; apps cannot post to the profiles of users - if you want someone to come back to your app, you could use a Request which will increment the counter on the user's bookmark for your app, but it's not possible to post to a user's profile 'from' a page or application

How to kick off Facebook Messenger conversation with user

I've seen this use case a few times.
A user goes to a company's web site and places an order with the company.
User logs into Facebook.
Messenger window shows up that says order confirmation # and now there's a chat between you and the business.
I'm trying to figure out how this is done.
Of course, if the user has given the app permissions or there was some Facebook integration on check out, then presumably the company has captured the user id and can send messages.
Is there any possible way that a company can send a message to a user by simply knowing their e-mail address? I think FB ids are scoped to Apps so even if you knew the user's FB Id, the ID on your app would be different. Any ideas?
I did it with ruby on rails.Let me give my articles about messenger bot.
This link show from scratch. and it uses this gem to make it happen. These are so useful articles. if you have additional questions, please let me know.

How to set privacy policy url for a fb app when working on localhost?

I am working on a local application that needs to retrieve data from user's Facebook profile. As long as I can see, by default I can only get name, picture and age range, but I need many others information like education, location, likes and so on. I tried to submit approval for these items, but Facebook won't set my submission because I don't have a Privacy Policy URL added. I don't know what Privacy Policy URL to add because I'm working on localhost.
Please help me figure it out and excuse me if my question is wrong, it's the first time when I work with fb api. Also, if there is another way to retrieve this items, I would be more than happy to hear about it.
Have a look at
https://developers.facebook.com/docs/apps/review/login#do-you-need-review
It's saying that
in order to help you craft your Facebook Login experience, your app's developers will be able to see, and grant, any permission without requiring review by Facebook.
and
Also, if you're the developer of an app and are the only person using it, then your app doesn't need to go through review. Since you're the developer, all app capabilities should be available. You will still need to take your app out of developer mode, but you should be able to do that without going through review.
So, to be able to develop your app and request extended permissions, you don't need to pass your app to review, as long as you test with an app admin/developer/tester.

Facebook OpenGraph: Getting like count of post without User Token

I have an existing app that uses the Facebook API & login that makes posts to the user's wall. For each post I store the id of that post.
What I need to accomplish is to gather like counts of those posts generated by the first app. I'm trying to write a small app that routinely pulls the like count. I've figured out how to get the like count of the post if I use a User Token - via Facebook Login. But since this app will run as a batch and not by a human, I don't want to use a Facebook login page. I could write code that simulates a user logging in but that would be a major ugly hack. I've tried to use an App Token but then the like count is always zero. I've found how to get the like count of a page without the need for a User Token http://www.techrecite.com/get-facebook-likes-count-of-a-page-using-graph-api/ but not a post
Is this even possible? If so how?
I've looked into Facebook API's subscription, but it doesn't seem possible to subscribe to a "like-a-post" event. Although I could be wrong. If so, could someone point me in the correct direction.
Thanks.

Django, track session even as user logs in and out

How do I track sessions in Django even after a user has logged in or out? I am using Django authentication.
For example, a user lands on the main page, and maybe follows a few links on my site. Then he logs in. Logs out. Follows some links. I want to track that this is the same user, or at least someone using the same browser session.
I am currently tracking
request.user.id
which is, of course, specific for a logged in user.
I thought I could use
request.session.session_key
to track the session, but the session_key changes when the user logs in and again when he logs out.
(What I really want to know is whether the person who lands on my page also logs in / signs up.)
Don't rely on the session cookie for this (because indeed, Django automatically rotates it across login / logouts — mainly to prevent session fixation attacks).
Instead, just create your own cookie, and track users that way.

How can I allow my users, who create pages on my website, to communicate back to those people who click the Facebook "Like" button on their pages?

OK, apologies for the verbose title. Let me give the background in a bit more detail.
My website allows my registered users to create new pages, each of which has its own unique URL. Each page has a Facebook "Like" button on it. I've already implemented Facebook Open Graph API meta tags so that the pages are proper open graph objects, and when some other visiting Facebook user "likes" the registered user's page, a post appears on that Facebook user's wall saying they have liked the page. The Facebook Like widget also displays the number of "likes" that page has received as normal. So far, so good.
What I want to do is allow my registered users to be able to communicate back to the Facebook users who have liked their page. The community of "likers" for a page is a potentially valuable social media resource to the registered user, if only they could communicate back.
I am aware of the "admin page" link you get beside the Like button, which can be used to post to these people, but that is not an option for my registered users as they have no privileges in relation to the Like button.
What I want to do, if possible, is setup a form to capture the registered user's message back to the Facebook users, and then my website sends the message on their behalf, without having to ask for any extra privileges from the Facebook users.
The following Facebook documentation pages seem to say this is possible, but having followed the Open Graph API documentation, I can't get it to work as described - http://developers.facebook.com/blog/post/465/ and http://developers.facebook.com/docs/reference/api/ ("Publishing" subsection). I can get the access token correctly in the first request, and plug that into the second request to do the post, but that doesn't seem to do anything and doesn't return any error.
Since it doesn't work for me, I'm wondering if this is possible as described, or do I need to get some sort of extra permission to do this? I've seen reference to offline_access permission but as I'm new to this stuff I am not sure how it would fit in. If I have to get the Facebook users to grant permissions, this is not going to work as envisaged.
Any thoughts would be most helpful.
The short answer: No, You will never been able to post on someones wall as another user.
The long answer:
You could try to ask for offline access but then you are asking the user to hand over all their facebook data and give you access todo whatever you like their accound, so that is not likely to happend.
The next problem is that they have to be friends to be able to post on each others walls.
Thats why Pages was implemented, so that organisations could announce/talk with the people interested.
However if you have created the like button correctly and give the pages correct meta data, you are able to post to user who have liked it.
Scroll down to Publishing:
http://developers.facebook.com/docs/opengraph/
Just add a form for your user and let your system publish to the correct page, you probably will need a offline token from your own account or similar to use on the server.
Another more complex way could be to generate a facebook page for each page you have on your server.
When the user creates a page on your system a page is created on facebook but as your app as admin.
And when another user likes the page they like the facebook page, hence you have the possibility to post in that page and speak to the user who liked it. (whooa thats a mouthfull).
