# AccountKit
A light-weight Ruby API client for [Facebook Account Kit](https://developers.facebook.com/docs/accountkit) with no dependency.
A demo of the Account Kit can be found [here](https://www.facebook.com/FacebookforDevelopers/videos/10153620979588553/).

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'account_kit'
```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install account_kit

## Usage

### Configuration

To work with Account Kit API, you need to provide Facebook App ID, Account Kit App Secret. If you don't specify an api version, the gem will call v1.0. You can also specify which version you want to use:

```
AccountKit.configure do |config|
  config.app_id = '1234566789'
  config.app_secret = 'abcdefghijklm'
  config.api_version = 'v1.0'
end
```

### API

We currently only supports [Authorization Code Flow](https://developers.facebook.com/docs/accountkit/accesstokens). Support for Client Access Token Flow will come in later versions.

To get access token, you need to provide the authorization code you get after user authenticate with Account Kit:

```
response = AccountKit.access_token(authorization_code)
json_response = JSON.parse(response)
access_token = json_response['access_token']
```

The response contains user's access token, use this token to get user's email or phone number:

```
response = AccountKit.me(access_token)
json_response = JSON.parse(response)
email = json_response[:email][:address]
phone_code = json_response[:phone][:country_prefix]
phone_number = json_response[:phone][:national_number]
```

## Development

After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).
