* 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 -X POST https://api.dropboxapi.com/2/files/get_temporary_link \
*     --header "Authorization: Bearer DROPBOX_ACCESS_TOKEN" \
*     --header "Content-Type: application/json" \
*     --data "{\"path\": \"/video.mp4\"}"

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

* The following JSON is sent in the request body.

* {
*   "path": "/video.mp4"
* }

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')
loJson = CreateObject('Chilkat.JsonObject')
loJson.UpdateString("path","/video.mp4")
