Tutorial: accessing Facebook API using C#

[@wilachamlong8644]

Can we get access token dynamically by Facebook account? Base on your demo, You can do any thing on your FB account only.

[@dylanwarrener5857]

So is this the same process for accessing and posting to an instagram account?

Hello, thank you for the good quality video. Will this work for C# winforms?

[@smokz98]

Hey, what if I want to do an application where the users authorize the program through a facebook app? I have seen some videos doing that but I don't know, cause I don't want that every person who want to do something have to look and search their own token and put it in the program.

Hey, Piotr. Thanks for the lesson, it is going to be mighty useful. Quick question. How difficult will it be to do this was a "Web Page"?

[@PiotrGankiewicz]

Hi Wayne, what exactly are you trying to achieve? Please give me more details :).

[@WayneBarroncffcs]

Hello, Piotr. OK. I have a page on FB, for our website. When a new Question is asked, I would like to have the post shared on our page. I usually do everything with .net in VB. But, if I can get it in C#, that will work as well. As the site is designed in ASP Classic. I am just going to send a call to the script during processing, and then have it take the URL and Title, and submit that to the FB page. So, that is the plan, anyway.

[@PiotrGankiewicz]

Hey, apologies for the late response. If you're using a classic ASP, it's possible that you could make use of the official Facebook SDK for C#. Otherwise, you can do it on your own, just like I did - just make use of the HttpClient to perform the HTTP request to the Facebook API. In your scenario, I'm not sure if you could get somehow notified by the FB API that e.g. new post was added on your fanpage. You will probably need to fetch the changes periodically from their API by your server, but maybe there's a better way of which I'm not aware of.

Any way to post message to all facebook friends via API?

[@jamessathyanathan4668]

I can get the Account ID and Account name but its not posting the message in my timeline

Your url is showing an error page. You still got that source somewhere, mate?

[@PiotrGankiewicz]

Which URL?

[@JayBlackthorne]

Sorry, posted this comment on the wrong video.

Jaki to wzorzec? takie rozdzielenie Client Service ?

[@PiotrGankiewicz]

Tu nie ma akurat żadnego specyficznego wzorca użytego (nie do końca też wiem o co dokładnie Ci chodzi).

[@sociell]

aha myślałem że jak do faceServis wstrzykrzniesz faceClient i korzystasz z funkcji daceclienta opakowane w metody faceServisu to wyjdzie wychodzić jakis wzorzec, ale się myliłem dzięki za odpowiedź

[@PiotrGankiewicz]

To tak naprawdę są dobre praktyki związane z dążeniem do abstrakcji w kodzie i używaniem interfejsów. Można to ew. podpiąć pod strategy pattern :).

Too much high resolution. Imposable to see code in a cell phone KZbin app.

Hi Piotr, can I commission you to make me a desktop app for FB sharing? I will need it for a photobooth app we're doing. Thanks.

[@PiotrGankiewicz]

Hi, I only work with .NET Core and JavaScript, thus it's not really possible to create a desktop app using C# unless you would consider something like Electron or so.

[@metamedian]

Hi Piotr, can you provide me the solution files for the post? I really need to make this app badly. We are trying to recreate it. Does it still work today? Facebook hasn't broken anything in it yet?

[@PiotrGankiewicz]

It still works, you can download the source code here: piotrgankiewicz.com/wp-content/uploads/2017/02/Facebook_API_NET_Core.zip

Hallo, does it still works for you ? I tried it , used newer api ( 7.0 ) and it seems does not work ... I am not sure if I now have to use some "Send dialog" solution from FB or not ... Thanks ! edit: What I want to do is publish the post on fb wall

[@ngthdinh94]

@@dusanbernath1891 hello, yes, it still works. I think the problem is your accessToken does not have the authorizations. Try with your accesstoken in FB graph explorer first to check the endpoint. If it does not work, Try to log in your FB with Google chrome (firefox does not work), then open this url m.facebook.com/composer/ocelot/async_loader/?publisher=feed , then search accessToken EAAA, then try with FB graph explorer

[@dusanbernath1891]

@@ngthdinh94 Hi , thanks for answer ( am aware of the fact this is not stackover... ) well with token provided it works well and I am able to post the message (locked) on my wall , but with my generated token it does not work ( just read works) I tried to tick all the items to in order to test my access token but it shows with some it have to be verified by someone and it is not available ( individual) for comapny you have to have business account ( I am individual user of application not the company or business ) ... So not sure what to do. I also would like to get know what is the loader you provided to me , whos "service" it is ? thanks !
