Medium SDK for PHP

Open source SDK for integrating Medium's OAuth2 API into your PHP application. Please note that Medium's API is still on an early stage and this implementation is not final. Breaking changes will happen. This SDK is unofficial. Medium's API documentation can be found here.

Installation

composer require jonathantorres/medium-sdk

Authentication

Initialize the SDK with your client credentials:

    use JonathanTorres\MediumSdk\Medium;

    $credentials = [
        'client-id' => 'CLIENT-ID',
        'client-secret' => 'CLIENT-SECRET',
        'redirect-url' => 'http://example.com/callback',
        'state' => 'somesecret',
        'scopes' => 'scope1,scope2',
    ];

    $medium = new Medium($credentials);

You can also use the connect method.

    use JonathanTorres\MediumSdk\Medium;

    $medium = new Medium();
    $medium->connect($credentials);

Browser-based authentication

Request the authentication url, this url will take the user to medium's authentication page. If successfull, it will return an authorization code.

    $authUrl = $medium->getAuthenticationUrl();

    <a href="<?php echo $authUrl; ?>">Authenticate with Medium</a>

Grab the authorization code from the url and use the authenticate method to be able to make requests to the API. Now you should be able to start making requests.

    $authorizationCode = $_GET['code'];
    $medium->authenticate($authorizationCode);

Generate a new access token

Access tokens are valid for 60 days. Once it expires, you can request a new access token using your refresh token. Refresh tokens do not expire. You can request a new access token using your refresh token.

    $accessToken = $medium->exchangeRefreshToken($refreshToken);
    $medium->setAccessToken($accessToken);

If you need to retrieve your refresh token after authentication, you can use the getRefreshToken(); method.

$refreshToken = $medium->getRefreshToken();

Authenticating with a self-issued access token

Medium recommends to use browser-based authentication, but you can also make requests to the API using a self-issued access token generated from your Medium settings page. These types of tokens never expire. Once you have it you can authenticate using this access token.

    $medium = new Medium('SELF-ISSUED-ACCESS-TOKEN');

You can also use the connect method.

    $medium = new Medium();
    $medium->connect('SELF-ISSUED-ACCESS-TOKEN');

Now you should be ready to start making requests to the API using your self issued access token.

Users

Get the authenticated user details.

This will return an object with the user's details:

    $user = $medium->getAuthenticatedUser();

    echo 'Authenticated user name is: ' . $user->data->name;

Publications

List the specified user publications

This will return an array of objects that represent a publication that the specified user is related to in some way.

    $publications = $medium->publications($userId)->data;

    foreach($publications as $publication) {
        echo 'Publication name: ' . $publication->name;
    }

List the contributors for the specified publication

This will return an array of users that are allowed to publish under the specified publication.

    $contributors = $medium->contributors($publicationId)->data;

    foreach($contributors as $contributor) {
        echo 'User ' . $contributor->userId . ' is an ' . $contributor->role . ' on ' . $contributor->publicationId;
    }

Posts

Creating a post

This will create a post on the authenticated user's profile. Provide the id of the authenticated user and the post data. This will return an object with the created post's details.

    $user = $medium->getAuthenticatedUser();
    $data = [
        'title' => 'Post title',
        'contentFormat' => 'html',
        'content' => 'This is my post content.',
        'publishStatus' => 'draft',
    ];

    $post = $medium->createPost($user->data->id, $data);

    echo 'Created post: ' . $post->data->title;

Creating a post under a publication

This will create a post on the authenticated user's profile but also associate it with a publication. Provide the same data as creating a post. The response will also be the same with the exception of adding the publicationId field.

    $data = [
        'title' => 'Post title',
        'contentFormat' => 'html',
        'content' => 'This is my post content.',
        'publishStatus' => 'draft',
    ];

    $post = $medium->createPostUnderPublication($publicationId, $data);

    echo 'Created post: ' . $post->data->title . ' under the publication ' . $post->data->publicationId;

Images

Uploading an image.

Provide an image resource, the image name and the extension. This will return an object with the uploaded image's data.

    $imageResource = fopen('path/to/your/image', 'r');
    $image = $medium->uploadImage($imageResource, 'image-filename.jpg');

    echo 'Uploaded image ' . $image->data->url . ' succesfully.';

Running the examples

After cloning your repo:

git clone [email protected]:jonathantorres/medium-sdk-php.git

Add your API credentials on examples/credentials.php

    $credentials = [
        'client-id' => 'YOUR-CLIENT-ID',
        'client-secret' => 'YOUR-CLIENT-SECRET',
        'redirect-url' => 'http://localhost:8888/callback.php',
        'state' => 'secret',
        'scopes' => 'basicProfile,publishPost,listPublications',
    ];

Start the included php server on the examples folder:

cd medium-sdk-php/examples && php -S localhost:8888

Run tests

Tests are written with PHPUnit.

After cloning your repo:

git clone [email protected]:jonathantorres/medium-sdk-php.git

Generate a self-issued access token from your Medium settings page. You need this to run the integration tests. Then, just run composer test on the project's root directory:

cd medium-sdk-php
export MEDIUM_TOKEN=YOUR_ACCESS_TOKEN; composer test
