Best way to make REST Call

Hello!

What is the best way to make a REST Call to an external API?

With a script in the run script task?

Do exist a plugin for that?

Thank you

Yep, a script is probably the most flexible and versatile option.
Something like the following:

var result,success;
var xhr = new ActiveXObject("Microsoft.XMLHTTP");
xhr.open("get", "http://www.my_rest_API/somequery", false );
xhr.send()
success = (xhr.status == 202 || xhr.status == 200));
result = xhr.responseText
