i mean.. in c# using RestSharp it's something along the lines of =>
var Client = new RestClient("WebsiteUrl");
var Request = new RestRequest("/api/cms/records/{dID}/{rID}" + "/?key=Api Key With perms", DataFormat.Json);
Request.AddUrlSegment("dID", 6);
Request.AddUrlSegment("rID", 1);
Request.AddParameter("fields[24]", "This changes record title");
var Response = Client.Post(Request);
if (Response.StatusCode == HttpStatusCode.OK)
{
// Convert Response.Content and/or Response.Data to class object
}
else Console.WriteLine(Response.StatusCode);
