Zoom API : Server to Server OAuth の利用

phpにてZoomAPIを使う際，いろいろなサンプルを参考にしたけどうまくいかなかったので，うまくいった方法を記録．

トークンを取得→予約するユーザー情報を取得→Zoom会議を予約，という流れ．

ini_set( 'display_errors', true );
ini_set( 'max_execution_time', 0 );




// zoom API の情報
$admin_email = 'hogehoge@fugafuga.net';

// Account ID
$account_id = 'xxxxxxxxxx';

// API Key
$client_id = 'xxxxxxxxxx';

// API Secret
$client_secret = 'xxxxxxxxxx';

// Secret Token
$secret_token = 'xxxxxxxxxx';

// Verification Token
$verification_token = 'xxxxxxxxxx';



//// トークンの取得
// POST method を利用する

$auth = base64_encode( $client_id . ':' . $client_secret );
