using System;
using System.Collections.Specialized;
using System.Net;

using (WebClient client = new WebClient())
{
byte[] response =
client.UploadValues("https://semaphore.co/api/v4/messages", new NameValueCollection()
{
{ "apikey", "" },
{ "number", "09998887777" },


{ "message", "I just sent my first message with Semaphore" },
{ "sendername", "SEMAPHORE" },
});
string result = System.Text.Encoding.UTF8.GetString(response);
}

Give this a try:

Sub PostIt()
    Dim objReq As Object
    Set objReq = CreateObject("MSXML2.ServerXMLHTTP")
    
    Dim postBody As String
    postBody = _
    "{" & _
        """apikey"": ""WRITE_API_KEY_HERE""," & _
        """number"": ""09998887777""," & _
        """message"": ""I just sent my first message with Semaphore""," & _
        """sendername"": ""SEMAPHORE""" & _
    "}"

    With objReq
        .Open "POST", "https://semaphore.co/api/v4/messages", False
        .setRequestHeader "Content-Type", "application/json"
        .Send postBody
        MsgBox .responseText
    End With
    
    Set objReq = Nothing
End Sub
