How do you call an endpoint from freemarker?

We have a use case where we would like to have and enpoint processed on the serverside. It would help our presentation a lot. I know rest calls can be made in java to get the data back from an endpoi...

Could you help me wrap my head around this? If I want to make a server to server call with the endpoint, and then want to use the resulting response with FreeMarker in a component (ie. use returned JSON data in a component without using javscript)... would that be possible? Thanks

Hi jlutterloh, 

 

sorry, as I know, it is not possible to do this in component (including endpoint result without JavaScript) at this moment.

 

if you worries about the UI "flashing" effect by including endpoint result with JavaScript, you may want to hide the outter div first, call the endpoint, add generated html and show the div. for exmaple,  I created an Endpoint in Studio which reaches some 3-rd party API and generate a HTML, and in my another component, I just do something like this.

 

<#assign kb_endpoint_url = "/plugins/custom/customer-id-goes-here/community-id-goes-here/endpoint-goes-name-here" />

(function($) {
        $(document).ready(function() {
        
                function callLithiumEndpoint() {
                
                    $('.my-div-css-class-goes-here').hide();
                    
                    var jqxhr = $.get("${kb_endpoint_url}" function(data) {
                      console.log("success");                     
                      $('.my-div-css-class-goes-here').prepend(data); 
                    })
                    .done(function() { console.log("second success"); })
                    .fail(function() { console.log("error"); })
                    .always(function() { console.log("finished"); $('.tmy-div-css-class-goes-here').show(); });                   
                }                
                callLithiumEndpoint();
        });
})(LITHIUM.jQuery);
</@liaAddScript>

 I hope that this is helpful for you.
