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

* This example uses the OAuth client credentials flow.
* See How to Create an Azure App Registration for OAuth 2.0 Client Credentials

* Use your client ID, client secret, and tenant ID in the following lines
loJson = CreateObject('Chilkat.JsonObject')
loJson.UpdateString("client_id","2871da2c-8176-4b7f-869b-2311aa82e743")
loJson.UpdateString("client_secret","2hu9Q~r5QuryUcEkNbg1btLtnfU1VUXzhSCG6brH")
loJson.UpdateString("scope","https://graph.microsoft.com/.default")
loJson.UpdateString("token_endpoint","https://login.microsoftonline.com/114d7ed6-71bf-4dbe-a866-748364121bf2/oauth2/v2.0/token")

loHttp = CreateObject('Chilkat.Http')
loHttp.AuthToken = loJson.Emit()

* List drives.
* You can specify a {siteId}, {groupId}, or {userId} in the URL
* to access document libraries for a group, a site, or a specific user.
* Use your specific Id instead of what we're using here:
loHttp.SetUrlVar("userId","4fe732c3-322e-4a6b-b729-2fd1eb5c6104")
lcResp = loHttp.QuickGetStr("https://graph.microsoft.com/v1.0/users/{$userId}/drives")
IF (loHttp.LastMethodSuccess <> 1) THEN
    ? loHttp.LastErrorText
    RELEASE loJson
    RELEASE loHttp
    CANCEL
ENDIF

* The response should be JSON.
loJson.EmitCompact = 0
loJson.Load(lcResp)

* A successful response should return a status code of 200.
IF (loHttp.LastStatus <> 200) THEN
    ? loJson.Emit()
    ? "Response status = " + STR(loHttp.LastStatus)
    RELEASE loJson
    RELEASE loHttp
    CANCEL
ENDIF

? loJson.Emit()

* Sample output:

* 	{
* 	  "@odata.context": "https://graph.microsoft.com/v1.0/$metadata#drives",
* 	  "value": [
* 	    {
* 	      "id": "3a33fceb9b74cc15",
* 	      "driveType": "personal",
* 	      "owner": {
* 	        "user": {
* 	          "displayName": "Matt Smith",
* 	          "id": "3a33fceb9b74cc15"
* 	        }
* 	      },
* 	      "quota": {
* 	        "deleted": 0,
* 	        "remaining": 1114571275977,
* 	        "state": "normal",
* 	        "total": 1115617755136,
* 	        "used": 1046479159
* 	      }
* 	    }
* 	  ]
* 	}

* Iterate over the drives in the JSON response:
i = 0
lnNumDrives = loJson.SizeOfArray("value")
DO WHILE i < lnNumDrives
    loJson.I = i
    ? "-- Drive " + STR(i + 1)
    ? "id: " + loJson.StringOf("value[i].id")
    * The size will be a number larger than what can fit in a 32-bit integer.
    * Get the integer as a string..
    ? "total: " + loJson.StringOf("value[i].quota.total")
    i = i + 1
