• PHP version ≥ 7.0
• Composer installed (dependency management tool)
• Project .env file configured

Install the SDK to your project via Composer:

composer require cregis/cregis-sdk-php:^2.0

After installation, Composer will automatically handle dependencies and generate vendor/autoload.php, and the framework will automatically load the SDK libraries.

• Ensure that the framework's vendor/autoload.php is correctly loaded (already handled by mainstream frameworks by default).
• For production environments, set ENVIRONMENT to production in the .env file to avoid using test environment interfaces.
• If the framework does not automatically load the .env file (e.g., ThinkPHP), you need to manually call Dotenv\Dotenv::createImmutable(__DIR__)->load(); to load the configuration.
