-- This example assumes the Chilkat HTTP API to have been previously unlocked.
-- See Global Unlock Sample for sample code.

-- Insert your Bearer token here:
local accessToken = "VOICEBASE_TOKEN"

local http = chilkat.Http.new()

-- Add the access (bearer) token to the request, which is a header
-- having the following format:
-- Authorization: Bearer <userAccessToken>
local sbAuth = chilkat.StringBuilder.new()
sbAuth:append("Bearer ")
sbAuth:append(accessToken)
http:set_request_header("Authorization", sbAuth:get_as_string())

local sbUrl = chilkat.StringBuilder.new()
sbUrl:append("https://apis.voicebase.com/v2-beta/media/$MEDIA_ID/transcripts/latest")
local replaceCount = sbUrl:replace("$MEDIA_ID", "f9b9bb88-d52c-4960-bcef-d516a9f85594")

local strJson = http:quick_get_str(sbUrl:get_as_string())
if not http.last_method_success then
    print(http.last_error_text)
    return
end

-- The response should be JSON, even if an error.
local json = chilkat.JsonObject.new()

-- See the sample JSON response below..

-- Iterate over the words..
