Docs

Each generated $token:

• is tied to a specific $action for which it is requested for;
• can have specified time-to-live ($ttl), where 0 means it never expires;
• can be used just specified number of times ($retries), while 0 retries means unlimited times to use token.

Requesting a new token

$tokenAPI = WP_AccessTokenAPI::getInstance();

$action  = 'post:123:delete'; // Action you want later to test against
$ttl     = 5; // minutes
$retries = 2; // can be triggered max 2x

try {
    $token = $tokenAPI->set($action, $ttl, $retries);
} catch (Exception $e) {
    // Handle error
}

// Use token, e.g: send token to user by mail...

Validating token

$tokenAPI = WP_AccessTokenAPI::getInstance();

if (isset($_GET['token']) && strlen(trim($_GET['token'])) > 0 && isset($_GET['action']) && $_GET['action'] === 'post:123:delete') {
    $authenticated = false;
    $action = $_GET['action'];
    $token  = $_GET['token'];

    try {
        $authenticated = $tokenAPI->validate($action, $token);
    } catch (Exception $e) {
        // Handle error
    }

    if ($authenticated) {
        // Delete post...
    }
}

Removing token

try {
    $removed = $tokenAPI->remove($action, $token);
} catch (Exception $e) {
    // Handle error
}

Enjoy!
