How do I execute a post function from the server in servicedesk plus?


Hi friends,
I need a popup window to send SMS to a specific phone number or perform other functions from a custom menu on a request page.
I have created an HTML file containing pop-up content and functions in JAVASCRIPT and moved it to the Integration\resources directory and a text file inthe Integration\custom_scripts\executor_files directory.
In a normal situation, if I want to execute a function and send some values to a specific URL, it will be sent from client's browser (like SEND-SMS.html in the attachments). and for security reasons, the URL called in the functions will be blocked by browsers or firewalls. how can I send my parameters to URLs directly from the server?
In other words: I need to use ServiceDesk plus Server to forward my parameters to specific URLs.
I have tried to do this like the SEND-SMS2.html file in the attachments, but I do not know how to use the URL "/servlet/ActionExecutorServlet" to send parameters from the server.
Do you have any documentation on this or other solutions that might solve my problem?
