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

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Http')
loHttp = CreateObject('Chilkat.Http')

* Implements the following CURL command:

* curl --request POST \
*   --url https://api.sendgrid.com/v3/mail/send \
*   --header 'authorization: Bearer YOUR_API_KEY' \
*   --header 'Content-Type: application/json' \
*   --data '{"personalizations": [{"to": [{"email": "recipient@example.com"}]}],"from": {"email": "sender@example.com"},"subject":"Hello, World!","content": [{"type": "text/html","value": "Hey,<br>Please find attachment."}], "attachments": [{"content": "BASE64_ENCODED_CONTENT", "type": "text/plain", "filename": "attachment.txt"}]}'

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

* Use this online tool to generate code from sample JSON:
* Generate Code to Create JSON

* The following JSON is sent in the request body.

* {
*   "personalizations": [
*     {
*       "to": [
*         {
*           "email": "recipient@example.com"

*       ]
*     }

*   "from": {
*     "email": "sender@example.com"
*   },
*   "subject": "Hello, World!",
*   "content": [
*     {
*       "type": "text/html",
*       "value": "Hey,<br>Please find attachment."
*     }
*   ],
*   "attachments": [
*     {
*       "content": "BASE64_ENCODED_CONTENT",
*       "type": "text/plain",
*       "filename": "attachment.txt"
*     }
*   ]
* }

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')
