FastComments PHP SSO SDK

Give your coding agent the FastComments context it needs - widgets, configuration, Secure SSO, the REST API, and the SDKs:

npx skills add fastcomments/skills

Works with Claude Code, Codex, Cursor, Copilot, Gemini, and every other agent the skills CLI supports.

composer require fastcomments/sso

Simple SSO

Simple SSO is straightforward to use, but provides less security than Secure SSO:

use FastComments\SSO\FastCommentsSSO;
use FastComments\SSO\SimpleSSOUserData;

// Create user data
$userData = SimpleSSOUserData::create(
    'username123',
    'user@example.com',
    'https://example.com/avatar.png'
);

// With URL-based login/logout
$sso = FastCommentsSSO::createWithUrls(
    null,
    $userData,
    'https://example.com/login',
    'https://example.com/logout'
);

// Or with callbacks
$sso = FastCommentsSSO::createWithCallbacks(
    $userData,
    function($url) { /* Handle login */ },
    function($url) { /* Handle logout */ }
);

// Get the token to pass to FastComments
$token = $sso->prepareToSend();

Secure SSO

Secure SSO provides enhanced security with HMAC verification:

use FastComments\SSO\FastCommentsSSO;
use FastComments\SSO\SecureSSOUserData;

// Create user data
$userData = SecureSSOUserData::create(
    'user-123',
    'user@example.com',
    'username123',
    'https://example.com/avatar.png'
);

// Add optional data if needed
$userData->isAdmin = true;
$userData->groupIds = ['group-1', 'group-2'];

// Create the SSO object with your API key
$sso = FastCommentsSSO::createSecure('your-api-key', $userData);

// Get the token to pass to FastComments
$token = $sso->prepareToSend();
