How do I find my Submail AppID and AppKey?

Log in to the [Submail Management Console](https://www.mysubmail.com/), navigate to the relevant project type (SMS, Mail, or Voice) and look for the 'AppID' and 'AppKey' in the project settings or credentials section.

Does this server handle MD5 signatures?

Yes! The server automatically calculates the required MD5 signature for every request using your provided AppKey, ensuring secure authorized communication with Submail APIs.

Can I send template-based SMS?
