I have question about FB messenger bot, any help would be apriciated!
I have a web application where we have FB login which gives us information about user and FB ID.
FB messenger also gives us an ID, but it's different from FB ID and I cannot find any connection between those 2.
Do we have a way to identify FB user by Messenger ID?
Thanks!
Yes there's a way actually,
it's not official but I've been using it for a while now.
Just retrieve the profile picture of the user in both Messenger and FB app.
Facebook provides profile pictures as URLs, and it's the same whether it's retrieved from Messenger or app.
So what you have to do is to store these URLs, and whenever you want to match profiles with Messengers, just compare the profile pictures links, and you'll be able to link your users profiles to their Messenger.
FB messenger also gives us an ID, but it's different from FB ID
Yes, it is called a page-scoped id (meaning it will be different for every page your bot runs on.)
https://developers.facebook.com/docs/messenger-platform/implementation#send_api:
These ids are page-scoped. These ids differ from those returned from Facebook Login apps which are app-scoped. You must use ids retrieved from a Messenger integration for this page in order to function properly.
and I cannot find any connection between those 2.
That’s because you are not supposed to.

The Facebook messenger bot API seems to require you create a Facebook app for each bot, for each page. The Facebook app stores the webhook, and connects to the page.
Is there a way to have a single Facebook app for many bots connected to many pages?
If you create a bot to resell to clients as a service, you need to be able to do this. But there does not seem to be any way. You need to create a Facebook app for each client, and go through the Facebook app review process for each page which is very difficult.
How can this be avoided?
Can a single Facebook app have multiple webhooks, or access to multiple pages messages?
You can create one chatbot and can use this bot in multiple Facebook pages. All you need is to store PAGE_ACCESS_TOKEN for each page and response messages to the user with right PAGE_ACCESS_TOKEN. You should get the necessary permissions to get page access tokens by Facebook Login. And then you need to subscribe the page to your chatbot(app): https://developers.facebook.com/docs/graph-api/reference/page/subscribed_apps
One important thing is Facebook generates a unique identifier for users for each page. Some user#A will have a different SENDER_ID/RECIPIENT_ID on different pages.
I'm trying the recent released Facebook Messenger Platform and so far so good. Everything worked well and I was able to create a echo bot.
But I'm wondering how I could identify this user that started chatting in my page. For example, when a user started chatting I get a PID user (page specific user id).
Making the follow request to Facebook Graph API:
GET https://graph.facebook.com/v2.6/{PAGE_SPECIFIC_USER_ID}
I discovered that I can just ask for the following fields: first_name,last_name and profile_pic.
So my question is, how could I discover if this user is a current customer of my business page? Is there another way of querying more information (like e-mail and real facebook user id)?
Facebook has updated the messenger platform API (2016-07-01) and introduced a new feature called Account Linking. This can be used to identify a user who has created an account on your website via Facebook Login and you can link the two accounts. Facebook login has its own set of permissions which can be used to get a lot more information via Facebook graph API. You can find the complete list here.
Currently, there's no way to do this. The best way would be to prompt the user to enter their information in chat or give them a link to a mobile login page or some other way of linking their account to the chat.
Messenger Platform 2.0 introduce "ID Matching API" ,that will solve the problem.
https://developers.facebook.com/docs/messenger-platform/connecting-accounts
you can retreive a user information like below using fbmq library https://github.com/conbus/fbmq
# this method will occur when a message received from user
#page.handle_message
def message_handler(event):
user_profile = page.get_user_profile(event.sender_id)
print(user_profile) #first_name, last_name, profile_pic, gender ...
I am using facebook to login to my website. The website does not need any information about the facebook user's friends' list. I am interested only in the user's general information.
https://developers.facebook.com/docs/reference/login/public-profile-and-friend-list/ shows the friend list also as the minimum information shared by Facebook.
Hence wanted to check if there is any way to restrict the user friend list information from being passed on from facebook to my application?
No, when a user authorize an application the minimum data shared is it's basic information and friend list.
Unfortunately you cannot change this.
Official documentation:
When someone connects with an app using Facebook Login, the app can
access their public profile and friend list, the pieces of information
that are visible to everyone. Each other piece of information that
someone adds to their Facebook profile is secured behind permissions.

We are building mobile app that uses Facebook for registration (know how to do this).
We would like to have a screen, where all your friends would be listed with indication, if they also use our app.
How should we save data (client, server) that one facebook user is also our app user?
When you're already using Facebook for authentication, you probably already have a column in the user table in your database that holds Facebook profile ids of each user. If you want to distinguish between them, just add a column modeling if that user is also using your mobile app.
By issuing a request to https://graph.facebook.com/PROFILE_ID/friends as described in the Facebook Graph API Documentation you can get the list of friends for a certain user without requiring any additional permissions.
Now just build the intersection between the friends list of the user and your (mobile app) user base and you got the list of his friends that are using your mobile app. You should of course do this comparision on the server, so you don't have to send the Facebook ids of your complete user base around.
I want to create facebook application that will allow to insert some data from my site to user's profile. User can choose to set up application. The users enters his ID on my site and when user's profile is viewed there is block of data loaded from my site (specified to the ID).
Is this possible to create such application with facebook ? If no the what type of application is closest to this? My site users want to display their profiles from my site inside their facebook profiles , so facebook friends can see this.
If I understand you correctly you want to add some additional data on the users Facebook profile, something like if Stackoverflow would add their flair on the Facebook profile.
I don't think this is possible, but you have a few alternatives:
Make the user post out a link to his profile on your site to his Facebook Wall, more details here.
Integrate your site to the new Open Graph Objects. Open Graph Objects will create a box on the users profile for your application which shows the users activity in your application. You should check out the demos and documentation for more information about this.
The users enters his ID on my site and when user's profile is viewed there is block of data loaded from my site
You can't do anything like this, you will need to use the authentication flow provided by Facebook in order to get access to the Facebook user data and then tie up the Facebook user to "your user", see documentation.
When it comes to what type of app you should create, there is basically only one type of app with some different options. But you should focus on the "Facebook for websites" documentation.
