Integrating with Facebook App

I'm doing a Facebook App version (runs in the browser) of my mobile app. How can I authenticate the user without creating a popup window? Better yet, how can we piggyback on the fact that the user is already logged into facebook and just put up a popup to grant access? I'm finding that the popup window for authentication is a HUGE barrier for users.

Using a different access code shouldn’t matter when logging in - internally we retrieve a user by its Facebook ID, which will be the same.
Thanks. It works create. Now i have another question:

when the access_token from facebook has changed, how do i prevent kinvey from creating a new user?
You should be able to use:



```

$kinvey.User.login({

_socialIdentity: {

facebook: {

access_token: '',

expires_in: ''

}

}

});

```
actually i am using cordova and angularjs.

I am able to call the cordova facebook plugin to retrieve the authorization token, but i cant find any documentation on how to pass the token back to kinvey using:



$kinvey.Social.connect(null, facebook');



could you help me on that?
I am not sure to what extend you are running into the same problem as reported by Daniel. Either way, in the requests it looks like you’re using `socialIdentity` instead of `_socialIdentity` (note the underscore), which will lead to the faulty behavior you described.
Hello Caroline, do you have any update on this?
No, I wasn't able to figure it out and hadn't heard back from engineering.
Hello

Did you ever make it work or got a response on this? I need to implement the same feature

Thanks...
Hi Daniel, I've got an engineer taking a look at this. Did you get anywhere with it since your last post?
Social Login isn't working for me in the REST API. When I first create the user, I get back an expected result - user data. If I try to login as that user using the facebook authentication I created it with, I get back 400 (bad request error):



This code creates the user, using the FB Javascript API to login to Facebook and get the authorization key:

var response = Kinvey.Persistence.Net.request(

"POST",

"https://baas.kinvey.com/user/APP_KEY",

{

"_socialIdentity":

{

"facebook":

{

"access_token":FB.getAuthResponse().accessToken,

"expires":FB.getAuthResponse().expiresIn

}

}



},

{

"Authorization": "Basic " + Kinvey.Persistence.Net.base64('APP_KEY:APP_SECRET'),

"X-Kinvey-API-Version": 3

}

)

That part works fine and it creates a new Kinvey user (though it should really be returning an existing user that already uses those credentials).



My understanding is that following code, identical except in the URL which I am adding /login to, should login using the same facebook account I just created the user with:

var response = Kinvey.Persistence.Net.request(

"POST",

"https://baas.kinvey.com/user/APP_KEY/login",

{

"_socialIdentity":

{

"facebook":

{

"access_token":FB.getAuthResponse().accessToken,

"expires":FB.getAuthResponse().expiresIn

}

}



},

{

"Authorization": "Basic " + Kinvey.Persistence.Net.base64('APP_KEY:APP_SECRET'),

"X-Kinvey-API-Version": 3

}

)



No dice, I get a 401 error:

It looks like the REST API is the way to go for this. It sounds like I can do an authentication with facebook's sdk, then use the resulting id and token in a Kinvey REST call.
Hey Daniel, I think that this depends on the requirements of Facebook-- I don't know if there's a decent way to get around it.
