Misfit login

This tutorial will show you how to misfit login, first things first, you need misfit account and create new application that allows you using api. To create new one, visit this create misfit application.

Once you have client id and secret, please read the instructions below to get start with misfit login.

Note: Misfit login using OAuth 2.0, for more information please read this article.

System requirements

  • PHP 5.4 or higher
  • APACHE 2.4.9 or higher
  • Netbean IDE

Project Structure

Implement code

Create projecthelper.php

We wrote one tutorial about projecthelper.php, view more at here, if you were already read it, please add this function in file, replace by your api key and secret

  • public static function get_misfit_config() {
    return $config = array(
    'client_id' => 'your-client-id',
    'client_secret' => 'client-secret',
    'redirect_uri' => self::get_base_url('misfit-callback.php'),
    'login' => self::get_base_url('misfit-login.php'),
    'session' => 'misfit_access_token'
    );
    }

Create misfit-login.php

This file will undertake two main tasks, check access_token in $_SESSION, if existed, send request to get user's profile, the opposite will create $authen_url for the user grant access your applications to connect to their accounts.

- Create $authen_url link if there is no access_token

  •  $auth_url = 'https://api.misfitwearables.com/auth/dialog/authorize?' .
    'client_id=' . $config['client_id'] .
    '&scope=profile' .
    '&response_type=code' .
    '&redirect_uri=' . $config['redirect_uri'];
    echo '<a href="' . $auth_url . '">Login with Misfit</a>';

- Send request to get user's profile and print result on screen.

  •  $access_token = $_SESSION[$config['session']];

    $endpoint = 'https://api.misfitwearables.com/move/resource/v1/user/me/profile';
    $header = array(
    'GET /move/resource/v1/user/me/profile HTTP/1.1',
    'Host: api.misfitwearables.com',
    'Authorization: Bearer ' . $access_token['access_token']
    );

    $data = projecthelper::make_request($endpoint, $header);
    var_dump($data);

<?php

if (!session_id()) {
session_start();
}
include './projecthelper.php';
$config = projecthelper::get_misfit_config();
if (isset($_SESSION[$config['session']])) {
$access_token = $_SESSION[$config['session']];

$endpoint = 'https://api.misfitwearables.com/move/resource/v1/user/me/profile';
$header = array(
'GET /move/resource/v1/user/me/profile HTTP/1.1',
'Host: api.misfitwearables.com',
'Authorization: Bearer ' . $access_token['access_token']
);

$data = projecthelper::make_request($endpoint, $header);
var_dump($data);
} else {
$auth_url = 'https://api.misfitwearables.com/auth/dialog/authorize?' .
'client_id=' . $config['client_id'] .
'&scope=profile' .
'&response_type=code' .
'&redirect_uri=' . $config['redirect_uri'];
echo '<a href="' . $auth_url . '">Login with Misfit</a>';
}

Create misfit-callback.php

After granted access to your application, user will be redirected to your redirect_uri with authentication code. Then you will make request to get access_token.
(In some cases, your redirect_uri that you provide must match with the one you've described in app's settings, or redirect_uri must begin with https).

+ Check and extract authentication code

  • Send request to get access_token
  •   $code = $_GET['code'];
    $endpoint = 'https://api.misfitwearables.com/auth/tokens/exchange';
    $header = array(
    'POST /auth/tokens/exchange HTTP/1.1',
    'Host: api.misfitwearables.com',
    );
    $post_fields = 'client_id=' . $config['client_id'] .
    '&client_secret=' . $config['client_secret'] .
    '&code=' . $code .
    '&redirect_uri=' . $config['redirect_uri'] .
    '&grant_type=authorization_code';
    $data = projecthelper::make_request($endpoint, $header, $post_fields);
  • Get result, if there is no error, save the result get into $_SESSION and navigate user to the login page.
  •  $_SESSION[$config['session']] = $data;
    header('Location: ' . $config['login']);
  • If there are errors, print to the screen
  •  print_r($data);

+ If there are errors, print to the screen

  • print_r($_GET);

<?php

if (!session_id()) {
session_start();
}
include './projecthelper.php';
$config = projecthelper::get_misfit_config();

if (isset($_GET['code'])) {
$code = $_GET['code'];
$endpoint = 'https://api.misfitwearables.com/auth/tokens/exchange';
$header = array(
'POST /auth/tokens/exchange HTTP/1.1',
'Host: api.misfitwearables.com',
);
$post_fields = 'client_id=' . $config['client_id'] .
'&client_secret=' . $config['client_secret'] .
'&code=' . $code .
'&redirect_uri=' . $config['redirect_uri'] .
'&grant_type=authorization_code';
$data = projecthelper::make_request($endpoint, $header, $post_fields);

if (is_array($data) && isset($data['access_token'])) {
$_SESSION[$config['session']] = $data;
header('Location: ' . $config['login']);
} else {
print_r($data);
}
} else {
print_r($_GET);
}

After implement code, run project and view result or you can view our example here. If you have questions, don't hesitate, tell us.
