I have a Post call that takes a string GUID "AA0DB615-D4CB-4466-BC23-0E0083002220"
I am using HTTPWebRequest to send request but I am not sure how to add this along with my Post request. Basically I have not found any method inside the HTTPWebRequest to send a Post that is just a string or a character datatype. Is their anything like request.AddBody

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://exampleapi.com");
                    request.ContentType = "application/json";
                    request.Method = "POST";

request.AddBody ???

What I have tried:

I am not sure how to add the post parameter to the body of the request.

You have to call GetRequestStream and write the request body to that stream.
WebRequest.GetRequestStream Method (System.Net) | Microsoft Docs[^]

NB: It might be easier to use the HttpClient class instead of the low-level WebRequest class:
HttpClient Class (System.Net.Http) | Microsoft Docs[^]
Call a Web API From a .NET Client (C#) - ASP.NET 4.x | Microsoft Docs[^]
