Question on calling REST API from Skuid snippet

Hi

Earlier, while using VF page we had the below snippet in use:

function tokenizeCreditCard(CCNumber){

        if ( CCNumber == null || CCNumber.length < 15 || CCNumber.length > 16 ) 
        {
            popupjQuery$('#creditCardErrorDiv').html( '<b>'+'Please enter valid 16 digit Credit Card Numbers'+'</b>');
            return false;
        }
        
        // Strip out spaces from input value
        var fixedCard = CCNumber.replace( /s+/g, "" );
        console.log( "noSpaces: '" + fixedCard + "'" );
        
        CCNumber = fixedCard;
        
        var token = "";
        var isDebug = false;
        var parsedJSON = "";
        //popupjQuery$("[id*='BPCardNumber']").val('');
        
        try 
        {
            var soapMsg = '{ "cc":"' + CCNumber + '"}'; //json request message
            sforce.connection.sessionId = "{!$Api.Session_ID}";
            // url : "{!sdtUrl}",
            
            sforce.connection.remoteFunction({
                url : "{!sdtEndpoint}",
                requestHeaders: 
                { 
                    "Content-Type": "Application/json",
                    "Authorization": "{!sdtHeader}"
                },
                mimeType: "text/plain",
                requestData: soapMsg,
                method: "POST",
                async: false,
                onSuccess: function(response)
                {   
                    console.log('I am in Success '+response);
                    
                    parsedJSON = JSON.parse(response);
                    
                    var cc = parsedJSON.cc;
                    var CCToken = parsedJSON.ccToken;
                    
                    if (typeof console != 'undefined') {
                      console.log('CCToken = '+CCToken);
                    }
                    if (typeof CCToken != 'undefined' &amp;&amp; CCToken!= '') {
                        
                        var lastDigits = CCToken.substring(CCToken.length - 4,CCToken.length);
                        var ccFormat = "**** **** **** "+lastDigits;
                        //popupjQuery$('.'+BPCardNumber).val(ccFormat);
                        popupjQuery$("[id*='BPCardNumber']").val(ccFormat);
                        errorMsg = '';
                    } else {
                        
                    }
                   
                    return;
                },
                onFailure: function(response)
                { 
                   console.log('error message on failure');
                    
                    var errorMsg = GetErrMsg(response);
                    
                    //popupjQuery$('#creditCardErrorDiv').html( 'Invalid Credit card number');
                    popupjQuery$('#creditCardErrorDiv').html( '<b>'+ errorMsg+'</b>');
                   
                    return;
                }
            });
        } catch(exception) {  
           console.log('exception message in catch block**');
           
        }
        
    } 

This function will send the CCard No# to an endpoint and get a token.

how to convert this into skuid’s snippet ?

How to get the sessionID and how does it work for sforce.connection.remoteFunction(){} ?

Any ideas ?
