How do I find my Chuanglan Account and Password?

Log in to the [Chuanglan Developer Portal](https://open.253.com/), navigate to the 'Application Management' or 'API Settings' section, and you will find your unique Account (username) and Password/Key for integration.

What is Variable SMS?

Variable SMS allows you to send template-based messages where specific placeholders (like names or codes) are replaced with different values for each recipient in a single API call.

Does this work for international numbers?

Yes! Use the `send_intl_sms` tool to reach users globally. Ensure you provide the phone number with the correct international country code.
