llSuccess = .F.

loHttp = createobject("CkHttp")
llSuccess = .F.

loSb = createobject("CkStringBuilder")
loSb.Append('{"greeting":"Hello World"}')

// This URL echoes the contents of the request body, letting us view it.
lcUrl = "https://chilkatsoft.com/echo_request_body.asp"

// Send a POST with the contents of the StringBuilder in the HTTP request body.
loResp = createobject("CkHttpResponse")
llSuccess = loHttp.HttpSb("POST",lcUrl,loSb,"utf-8","application/json",loResp)
if (llSuccess = .F.) then
    ? loHttp.LastErrorText
    release loHttp
    release loSb
    release loResp
    return
endif

? "Response Status Code: " + str(loResp.StatusCode)

// Examine the request we sent.
// The LastHeader property stores the HTTP request header of the most recent request sent,
// and in this instance, the response body mirrors the request body.
? loHttp.LastHeader
? loResp.BodyStr

// Output:

// POST /echo_request_body.asp HTTP/1.1
// Host: chilkatsoft.com
// Accept: */*
// Accept-Encoding: gzip
// Content-Type: application/json
// Content-Length: 26
// 
// {"greeting":"Hello World"}
