clef / clef-php

A PHP library for the Clef API

Clef PHP bindings

A PHP wrapper for the Clef API. Authenticate a user and access their information in two lines of code.

You can sign up for a Clef account at https://getclef.com.

Requirements

PHP 5.3.3 and later.

Composer

You can install the bindings via Composer. Add this to your composer.json:

{
  "require": {
    "clef/clef-php": "1.*"
  }
}

Then install via:

composer install

To use the bindings, use Composer's autoload:

require_once('vendor/autoload.php');

Manual Installation

If you do not wish to use Composer, you can download the latest release. Then, to use the bindings, include the init.php file.

require_once('/path/to/clef-php/init.php');

Usage

Logging in a user

When a user logs in with Clef, the browser will redirect to your data-redirect-url. To retrieve user information, call get_login_information in that endpoint:

\Clef\Clef::initialize(APP_ID, APP_SECRET);
$response = \Clef\Clef::get_login_information($_GET["code"]);

For what to do after getting user information, check out our documentation on Associating users.

Logging out a user

When you configure your Clef integration, you can also set up a logout hook URL. Clef sends a POST to this URL whenever a user logs out with Clef, so you can log them out on your website too.

\Clef\Clef::initialize(APP_ID, APP_SECRET);
$clef_id = \Clef\Clef::get_logout_information($_POST["logout_token"]);

For what to do after getting a user who's logging out's clef_id, see our documentation on Database logout.
