' See Global Unlock Sample for sample code.

Dim http As New Chilkat.Http
Dim success As Boolean

' Implements the following CURL command:

' curl -H "Authorization: Bearer token_api_oauth" \
' "https://api.smsapi.com/sms.do?from=sender_name&to=44123456789&message=message_content&format=json"

' Use the following online tool to generate HTTP code from a CURL command
' Convert a cURL Command to HTTP Source Code

' Adds the "Authorization: Bearer token_api_oauth" header.
http.AuthToken = "token_api_oauth"

Dim messageContent As String = "Hello" & vbCrLf & "This is a test" & vbCrLf & "with multiple lines of text."

' Given that our message contentn has newlines, we obviously cannot put newlines in a URL without them being URL encoded..
' Therefore.. URL encode..
Dim sbMessage As New Chilkat.StringBuilder
