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

loHttp = CreateObject('Chilkat.Http')

* Implements the following CURL command:

* curl -X POST "https://api.x.com/2/tweets" \
* -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
* -H "Content-Type: application/json" \
* -d '{"text":"Hello, X.com! This is my first post using the API."}'

* Generate Code to Create JSON

* The following JSON is sent in the request body.

* {
*   "text": "Hello, X.com! This is my first post using the API."
* }

loJson = CreateObject('Chilkat.JsonObject')
loJson.UpdateString("text","Hello, X.com! This is my first post using the API.")

* Adds the "Authorization: Bearer YOUR_ACCESS_TOKEN" header.
* Get our access token.
