* This example requires 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')

* Use your previously obtained access token here:
* See the following examples for getting an access token:
*    Get Microsoft Graph OAuth2 Access Token (Azure AD v2.0 Endpoint).
*    Get Microsoft Graph OAuth2 Access Token (Azure AD Endpoint).
*    Refresh Access Token (Azure AD v2.0 Endpoint).
*    Refresh Access Token (Azure AD Endpoint).

loHttp.AuthToken = "MICROSOFT_GRAPH_ACCESS_TOKEN"

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

* Sends:  GET /users/{user_id | userPrincipalName}/messages/{message_id}/attachments
* Note: It is also possible to use the literal string "me" for the current logged-on user.
* For example: GET /me/messages/{message_id}/attachments

loHttp.ClearUrlVars()
loHttp.SetUrlVar("userPrincipalName","chilkatsoft@outlook.com")

* Assume we already have a message ID from previously listing the messages in a folder
lcMessageId = "AAMkADYzZWE3YmZmLWU0YzgtNGNkZC04MGE1LWFiYTFlNTRlY2QwYQBGAAAAAAAu7cUXL5YOTrdsUIw7-v8FBwBUcG0qWqkmQYqWLHQataQxAACnwqJUAABUcG0qWqkmQYqWLHQataQxAACnwrnOAAA="
loHttp.SetUrlVar("message_id",lcMessageId)

* Send the request to download the attachments.
lnSuccess = loHttp.QuickGetSb("https://graph.microsoft.com/v1.0/users/{$userPrincipalName}/messages/{$message_id}/attachments",loSbResponse)
IF ((lnSuccess <> 1) AND (loHttp.LastStatus = 0)) THEN
    ? loHttp.LastErrorText
    RELEASE loHttp
    RELEASE loSbResponse
    CANCEL
ENDIF

* The attachment data is contained within the JSON response.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')
loJson = CreateObject('Chilkat.JsonObject')
loJson.LoadSb(loSbResponse)
loJson.EmitCompact = 0

? "Status code = " + STR(loHttp.LastStatus)
IF (loHttp.LastStatus <> 200) THEN
    ? loJson.Emit()
    ? "Failed."

* This is a sample JSON response.  The code for parsing and extracting/saving the attachments
* is shown below.
