SMS Integration Tutorial?

I haven’t integrated SMS with Wappler yet.
I already have a page that saves a form to a database & then sends an html email.
It would be a logical place to attach this SMS.php script –
& I thought of starting by copying the script into a Server Action folder & calling for it & then mapping the variables available from the send-email action.

But, the php files in Server actions are just json structure & this script is actually a PHP script.

I see questions about using different API scripts from different online SMS hosts but no overall Tutorial on the best Wappler steps to start with –

(I know curl is installed on my hosting account)

For those who have already done something similar would you give me some pointers?

Thank you!
