OAuth client library specific to access MDirector API services, written in PHP.

This package provides MDirector (http://www.mdirector.com) OAuth 2.0 support for the 
PHP League's [OAuth 2.0 Client](https://github.com/thephpleague/oauth2-client).

As of now, only an OAuth2 implementation for the MDirector email marketing and transactional 
applications are provided. 
The package is composed of two [oauth2-client](https://github.com/thephpleague/oauth2-client) 
providers (for the email marketing and transactional services) and wrappers around them 
to hide the burden of the required OAuth2 negotiations.

As a consumer you may choose to use just a provider or a client wrapper, as it suits you best.

There is also a command line script to help you test it from the shell.

## Requirements
The following versions of PHP are supported.

* PHP 5.6
* PHP 7.0
* PHP 7.1
* PHP 7.2

## Installation
```
composer require antevenio/oauth2-mdirector 
```

## Usage
As mentioned before, you can choose to use just a provider or the wrapper around it. 
Here you can find examples for each case: 

### 1. MDirector Oauth2-client provider (email marketing application)
You can find the [oauth2-client](https://github.com/thephpleague/oauth2-client) provider under 
[OAuth2/Client/Provider](https://github.com/Antevenio/mdirector-oauth-client-php/tree/master/src/OAuth2/Client/Provider), 
for generic usage instructions please refer to generic usage in the
[oauth2-client github project](https://github.com/thephpleague/oauth2-client).

The MDirector email marketing provider as of now is just providing the **Resource Owner Password Credentials Grant** 
having a generic clientId named **webapp**. Here is an example to get a valid accessToken:

```php
$provider = new \MDOAuth\OAuth2\Client\Provider\MDirector();

try {
    // Try to get an access token using the resource owner password credentials grant.
    $accessToken = $provider->getAccessToken('password', [
        'username' => '{yourCompanyId}',
        'password' => '{yourApiSecret}'
    ]);
} catch (\League\OAuth2\Client\Provider\Exception\IdentityProviderException $e) {
    // Failed to get the access token
    exit($e->getMessage());
}
```

When building your requests to the transactional api, take into account that our api expects the
parameters to be on the query string for *GET* requests, or being 
application/x-www-form-urlencoded on the body of the request for any other method

i.e. *POST*, *PUT*, *DELETE*... etc.

### 2. Transactional Oauth2-client provider (transactional application)
You can find the [oauth2-client](https://github.com/thephpleague/oauth2-client) provider under 
[OAuth2/Client/Provider](https://github.com/Antevenio/mdirector-oauth-client-php/tree/master/src/OAuth2/Client/Provider), 
for generic usage instructions please refer to generic usage in the
[oauth2-client github project](https://github.com/thephpleague/oauth2-client).

The Transactional provider as of now is just providing the **Resource Owner Password Credentials Grant** 
having a generic clientId named **webapp**. Here is an example to get a valid accessToken:

```php
$provider = new \MDOAuth\OAuth2\Client\Provider\Transactional();

try {
    // Try to get an access token using the resource owner password credentials grant.
    $accessToken = $provider->getAccessToken('password', [
        'username' => '{yourCompanyId}',
        'password' => '{yourApiSecret}'
    ]);
} catch (\League\OAuth2\Client\Provider\Exception\IdentityProviderException $e) {
    // Failed to get the access token
    exit($e->getMessage());
}
```

When building your requests to the mdirector api, take into account that our api expects the
parameters to be on the query string for *GET* requests, or being 
application/json encoded on the body of the request for any other method 
                                                         
i.e. *POST*, *PUT*, *DELETE*... etc.

The headers:
```
Content-Type: application/json
```
and
```
Accept: application/json
```
Are required on every request.

### 3. Wrapper clients
The wrapper clients offer a simplified way to call the API. 
They take care of obtaining tokens and refreshing them where needed. 
You just have to set parameters as an associative array, 
the wrapper knows how to pass them depending on the specified method. 
You can also specify a custom user-agent to be send on request headers 
("*oauth2-mdirector client*" by default)

Example of use:
```php
$companyId = 'yourCompanyId';
$secret = 'yourApiSecret';

$client = (new \MDOAuth\OAuth2\Wrapper\MDirector\Factory())->create($companyId, $secret);
$response = $client->setUri('https://api.mdirector.com/api_contact')
    ->setMethod('get')
    ->setParameters([
        'email' => 'myemail@mydomain.org'    
    ])
    ->setUserAgent('MyOwnUserAgent 1.0')
    ->request();

echo $response->getBody()->getContents();
```

### 3. Shell script
The library also provides a [console](https://github.com/symfony/console) client so you can 
call the mdirector api from a shell.
To do so run:

```
$ ./bin/mdirector-oauth-client oauth2:mdirector --help    
```                                            
The command will display some self explanatory help about its usage and parameters.


### 4. Others

If you plan on using another client implementation, or have to call the API using a language other than PHP,
here you'll find the little bits of information you'll need to know:

You'll be asking for access tokens using "***webapp***" as your fixed clientId, 
specifying **password** as the grant type, 
being your *company id* your **username** and your *secret* your **password**. 

The endpoint for getting such tokens (or refresh them) would be:

https://app.mdirector.com/oauth2

And you'll be carrying your token on a Bearer header in your requests. 
(https://oauth.net/2/bearer-tokens/)
