Same as runNoAuthFacebookT, but uses Facebook's beta tier
(see https://developers.facebook.com/support/beta-tier/).
Phantom type stating that you have provided your
Credentials and thus have access to the whole API.
Phantom type stating that you have not provided your
Credentials. This means that you'll be limited about which
APIs you'll be able use.

Access token
data AccessToken kind where Source #
An access token. While you can make some API calls without an access token, many require an access token and some will give you more information with an appropriate access token.
There are two kinds of access tokens:
- User access token
- An access token obtained after an user accepts your application. Let's you access more information about that user and act on their behalf (depending on which permissions you've asked for).
- App access token
- An access token that allows you to take administrative actions for your application.
These two kinds of access tokens are distinguished by the
phantom type on AccessToken, which can be UserKind or
AppKind.

True if the access token has expired, otherwise False.
isValid :: (MonadResource m, MonadUnliftIO m) => AccessToken anyKind -> FacebookT anyAuth m Bool Source #
True if the access token is valid. An expired access
token is not valid (see hasExpired). However, a non-expired
access token may not be valid as well. For example, in the
case of an user access token, they may have changed their
password, logged out from Facebook or blocked your app.
setApiVersion :: MonadIO m => ApiVersion -> FacebookT anyAuth m () Source #
Set the Graph API version.
getApiVersion :: MonadIO m => FacebookT anyAuth m ApiVersion Source #

Get an app access token from Facebook using your credentials. Ref: https://developers.facebook.com/docs/facebook-login/manually-build-a-login-flow
User access token
Phantom type used mark an AccessToken as an user access
token.
type RedirectUrl = Text Source #
URL where the user is redirected to after Facebook authenticates the user authorizes your application. This URL should be inside the domain registered for your Facebook application.
data Permission Source #
A permission that is asked for the user when he authorizes your app. Please refer to Facebook's documentation at https://developers.facebook.com/docs/reference/api/permissions/ to see which permissions are available.
This is a newtype of Text that supports only IsString.
This means that to create a Permission you should use the
OverloadedStrings language extension. For example,

getUserAccessTokenStep1 :: (Monad m, MonadIO m) => RedirectUrl -> [Permission] -> FacebookT Auth m Text Source #
The first step to get an user access token. Returns the
Facebook URL you should redirect you user to. Facebook will
authenticate the user, authorize your app and then redirect
the user back into the provider RedirectUrl.
getUserAccessTokenStep2 Source #
Arguments
| :: (MonadResource m, MonadUnliftIO m, MonadThrow m, MonadIO m) | |
| => RedirectUrl | Should be exactly the same
as in |
| -> [Argument] | Query parameters. |
| -> FacebookT Auth m UserAccessToken |
The second step to get an user access token. If the user is
successfully authenticate and they authorize your application,
then they'll be redirected back to the RedirectUrl you've
passed to getUserAccessTokenStep1. You should take the
request query parameters passed to your RedirectUrl and give
to this function that will complete the user authentication
flow and give you an AccessToken
Arguments
| :: Monad m | |
| => UserAccessToken | The user's access token. |
| -> RedirectUrl | URL the user should be directed to in your site domain. |
| -> FacebookT Auth m Text | Logout URL in
|
The URL an user should be redirected to in order to log them out of their Facebook session. Facebook will then redirect the user to the provided URL after logging them out. Note that, at the time of this writing, Facebook's policies require you to log the user out of Facebook when they ask to log out of your site.
Note also that Facebook may refuse to redirect the user to the
provided URL if their user access token is invalid. In order
to prevent this bug, we suggest that you use isValid before
redirecting the user to the URL provided by getUserLogoutUrl
since this function doesn't do any validity checks.
extendUserAccessToken :: (MonadResource m, MonadUnliftIO m, MonadThrow m, MonadIO m) => UserAccessToken -> FacebookT Auth m (Either FacebookException UserAccessToken) Source #
Extend the expiration time of an user access token (see
https://developers.facebook.com/docs/offline-access-deprecation/,
https://developers.facebook.com/roadmap/offline-access-removal/).
Only short-lived user access tokens may extended into
long-lived user access tokens, you must get a new short-lived
user access token if you need to extend a long-lived
one. Returns Left exc if there is an error while extending,
or Right token with the new user access token (which could
have the same data and expiration time as before, but you
can't assume this). Note that expired access tokens can't be
extended, only valid tokens.
Arguments
| :: (MonadResource m, MonadUnliftIO m, MonadThrow m) | |
| => AppAccessToken | Your app access token. |
| -> AccessTokenData | The access token you want to debug. |
| -> FacebookT Auth m DebugToken |

A tag (i.e. "I'll tag you on my post").
Pagination
Many Graph API results are returned as a JSON object with the following structure:
{
"data": [
...item 1...,
:
...item n...
],
"paging": {
"previous": "http://...link to previous page...",
"next": "http://...link to next page..."
}
}
Only the "data" field is required, the others may or may
not appear.
A Pager a datatype encodes such result where each item has
type a. You may use functions fetchNextPage and
fetchPreviousPage to navigate through the results.
fetchNextPage :: (MonadResource m, FromJSON a, MonadThrow m, MonadUnliftIO m) => Pager a -> FacebookT anyAuth m (Maybe (Pager a)) Source #
fetchPreviousPage :: (MonadResource m, FromJSON a, MonadThrow m, MonadUnliftIO m) => Pager a -> FacebookT anyAuth m (Maybe (Pager a)) Source #
Tries to fetch the previous page of a Pager. Returns
Nothing whenever the current Pager does not have a
pagerPrevious.

Real-time update notifications
Subscriptions
Arguments
| :: (MonadResource m, MonadUnliftIO m, MonadThrow m) | |
| => RealTimeUpdateObject | Type of objects whose subscription you and to add or modify. |
| -> [RealTimeUpdateField] | Fields that you are interested in receiving updates. |
| -> RealTimeUpdateUrl | Your callback URL. |
| -> RealTimeUpdateToken | A verification token. |
| -> AppAccessToken | Access token for your app. |
| -> FacebookT Auth m () |
Add or modify a subscription for real-time updates. If
there were no previous subscriptions for the given
RealTimeUpdateObject, then a new subscription is created.
If there was any previous subscription for the given
RealTimeUpdateObject, it's overriden by this one (even if
the other subscription had a different callback URL).
listSubscriptions :: (MonadResource m, MonadUnliftIO m, MonadThrow m) => AppAccessToken -> FacebookT Auth m [RealTimeUpdateSubscription] Source #
List current real-time update subscriptions.
data RealTimeUpdateObject Source #
The type of objects that a real-time update refers to.
Constructors
| UserRTUO | |
| PermissionsRTUO | |

Instances
type RealTimeUpdateField = ByteString Source #
A field of a RealTimeUpdateObject that you would like to
receive notifications when changed.
type RealTimeUpdateUrl = Text Source #
The URL on your server that will receive the real-time updates. Please refer to Facebook's documentation in order to see what this URL needs to implement.
type RealTimeUpdateToken = ByteString Source #
A token that is sent back by Facebook's servers to your server in order to verify that you really were trying to modify your subscription.
data RealTimeUpdateSubscription Source #
Information returned by Facebook about a real-time update notification subscription.

Notifications
verifyRealTimeUpdateNotifications Source #
Arguments
| :: (Monad m, MonadIO m) | |
| => ByteString |
|
| -> ByteString | Request body with JSON-encoded notifications. |
| -> FacebookT Auth m (Maybe ByteString) |
Verifi(es the input's authenticity (i.e. it comes from, MonadIO m)
Facebook) and integrity by calculating its HMAC-SHA1 (using
your application secret as the key) and verifying that it
matches the value from the HTTP request's X-Hub-Signature
header's value. If it's not valid, Nothing is returned,
otherwise Just data is returned where data is the original
data.
getRealTimeUpdateNotifications Source #
Arguments
| :: (Monad m, FromJSON a, MonadIO m) | |
| => ByteString |
|
| -> ByteString | Request body with JSON-encoded notifications. |
| -> FacebookT Auth m (Maybe (RealTimeUpdateNotification a)) |
Same as verifyRealTimeUpdateNotifications but also parses
the response as JSON. Returns Nothing if either the
signature is invalid or the data can't be parsed (use
verifyRealTimeUpdateNotifications if you need to distinguish
between these two error conditions).
data RealTimeUpdateNotification a Source #
When data changes and there's a valid subscription, Facebook
will POST to your RealTimeUpdateUrl with a JSON-encoded
object containing the notifications. A
'RealTimeUpdateNotification a' represents such object where
a is type of the entries (e.g.,
RealTimeUpdateNotificationUserEntry).
If you have a single RealTimeUpdateUrl for different kinds
of notifications, you may parse a RealTimeUpdateNotification
and then manually parse the ValueValue depending on
the value of rtunObject.
We recommend using getRealTimeUpdateNotifications.

FQL
Arguments
| :: (MonadResource m, MonadUnliftIO m, MonadThrow m, FromJSON a) | |
| => Text | FQL Query |
| -> Maybe (AccessToken anyKind) | Optional access token |
| -> FacebookT anyAuth m (Pager a) |
Query the Facebook Graph using FQL.
Deprecated: Deprecated since fb 0.14.7, please use FbUTCTime instead.
newtype wrapper around UTCTime that is able to parse
FQL's time representation as seconds since the Unix epoch.
Constructors
| FQLTime | Deprecated: Deprecated since fb 0.14.7, please use FbUTCTime instead. |
newtype wrapper around lists that works around FQL's
strange lists.
For example, if you fetch the tagged_uids field from
location_post, you'll find that Facebook's FQL represents an
empty list of tagged UIDs as plain JSON array ([]).
However, it represents a singleton list as an object
{"1234": 1234} instead of the much more correct [1234].
On the other hand, not all FQL arrays are represented in this
bogus manner. Also, some so-called arrays by FQL's
documentation are actually objects, see FQLObject.

| Eq a => Eq (FQLList a) Source # | |
| Ord a => Ord (FQLList a) Source # | |
| Show a => Show (FQLList a) Source # | |
| FromJSON a => FromJSON (FQLList a) Source # | |
newtype wrapper around any object that works around FQL's
strange objects.
For example, if you fetch the app_data field from stream,
you'll find that empty objects are actually represented as
empty lists [] instead of a proper empty object {}. Also
note that FQL's documentation says that app_data is an
array, which it clear is not. See also FQLList.

makeFriendConn :: (MonadResource m, MonadUnliftIO m, MonadThrow m) => TestUser -> TestUser -> FacebookT Auth m () Source #
Make a friend connection between two test users.
This is how Facebook's API work: two calls must be made. The first call has the format: "/userA_id/friends/userB_id" with the access token of user A as query parameter. The second call has the format: "/userB_id/friends/userA_id" with the access token of user B as query parameter. The first call creates a friend request and the second call accepts the friend request.
