type UserAccessToken = AccessToken UserKind

Type synonym for AccessToken UserKind.

data AccessToken kind where

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.

Constructors

UserAccessToken :: UserId -> AccessTokenData -> UTCTime -> AccessToken UserKind
AppAccessToken :: AccessTokenData -> AccessToken AppKind

ToJSON (AccessToken kind)	Since 0.14.9. Not a Facebook JSON format, but a custom `fb` format for convenience if you need to serialize access tokens.
ParseAccessToken kind => FromJSON (AccessToken kind)	Since 0.14.9. Parses the format that `ToJSON` produces. Note that you need to statically decide whether you want to parse a user access token or an app access token.
