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

* Get the previously obtained access token.
* See Get Google Photos Access Token.

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')
loJsonToken = CreateObject('Chilkat.JsonObject')
lnSuccess = loJsonToken.LoadFile("qa_data/tokens/googlePhotos.json")

loHttp.AuthToken = loJsonToken.StringOf("access_token")

* For more information, see Google Photos Upload Media REST API Documentation

* Build a JSON body that looks like this:
* {
*   "albumId": "ALBUM_ID",
*   "newMediaItems": [
*     {
*       "description": "ITEM_DESCRIPTION",
*       "simpleMediaItem": {

*       }
*     }
*    , ...
*   ]
* }

* Build the above JSON:
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')
loJson = CreateObject('Chilkat.JsonObject')
loJson.UpdateString("albumId","ALBUM_ID")

    RELEASE loHttp
    RELEASE loJson
    CANCEL
ENDIF

* Examine the response status code.  Success is indicated by a status code of 200.
? "response status code: " + STR(loResp.StatusCode)
