Mastodon API PHP

PHP wrapper for the Mastodon API that includes oAuth helpers, Guzzle based.

Build Status

Getting started

Install it via Composer.

composer require colorfield/mastodon-api

Mastodon API and instances

This is a plain API wrapper, so the intention is to support further changes in the API by letting the developer pass the desired endpoint.

  1. Get the REST Mastodon documentation.
  2. Get an instance from the instance list.

Quick test


An interactive demo is available.

  1. Clone the GitHub repository.
  2. cd in the cloned directory
  3. Run composer install
  4. Run php -S localhost:8000
  5. In your browser, go to http://localhost:8000/test_oauth.php
  6. You will get the client_id and client_secret, click on the authorization URL link, then confirm the authorization under Mastodon and copy the authorization code.
  7. Get the bearer: click on the "Get access token" button.
  8. Authenticate with your Mastodon username (email) and password: click on "Login".

Authorize your application

Authorize your application

Mastodon API

  1. Make your own copy of test_credentials.example.php as test_credentials.php
  2. Define in test_credentials.php the information obtained with oAuth and your Mastodon email and password.
  3. In your browser, go to http://localhost:8000/test_api.php

Authenticate with oAuth

Register your application

Give it a name and an optional instance. The instance defaults to

$name = 'MyMastodonApp';
$instance = '';
$oAuth = new Colorfield\Mastodon\MastodonOAuth($name, $instance);

The default configuration is limited the the 'read' and 'write' scopes. You can modify it via

$oAuth->config->setScopes(['read', 'write', 'follow']);

Note that this must be done while obtaining the token so you cannot override this after. More about scopes.

Get the authorization code

  1. Get the authorization URL $authorizationUrl = $oAuth->getAuthorizationUrl();
  2. Go to this URL, authorize and copy the authorization code.

Get the bearer

  1. Store the authorization code in the configuration value object. $oAuth->config->setAuthorizationCode(xxx);

  2. Then get the access token. As a side effect, stores it on the configuration value object. $oAuth->getAccessToken();

Use the Mastodon API

Instantiate the Mastodon API with the configuration

The oAuth credentials should be stored from the configuration value object for later retrieval. Then you can use it in this way.

$name = 'MyMastodonApp';
$instance = '';
$oAuth = new Colorfield\Mastodon\MastodonOAuth($name, $instance);
$mastodonAPI = new Colorfield\Mastodon\MastodonAPI($oAuth->config);

User login

Login with Mastodon email and password. $oAuth->authenticateUser($email, $password);

Use the API wrapper

Here are a few examples of the API wrapper usage. Read the full documentation.


Get credentials

$credentials = $mastodonAPI->get('/accounts/verify_credentials');

Get followers

$followers = $mastodonAPI->get('/accounts/USER_ID/followers');


Clear notifications

$clearedNotifications = $mastodonAPI->post('/notifications/clear');

@todo complete with delete and stream.
