Procedure Test
    Variant vOauth2
    Handle hoOauth2
    Handle hoRest
    Boolean iBAutoReconnect
    Boolean iSuccess
    String sResponseJson
    String sTemp1
    Boolean bTemp1

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

    // This example assumes we previously obtained an access token
    Get Create (RefClass(cComChilkatOAuth2)) To hoOauth2
    If (Not(IsComObjectCreated(hoOauth2))) Begin
        Send CreateComObject of hoOauth2
    End
    Set ComAccessToken Of hoOauth2 To "FACEBOOK-ACCESS-TOKEN"

    Get Create (RefClass(cComChilkatRest)) To hoRest
    If (Not(IsComObjectCreated(hoRest))) Begin
        Send CreateComObject of hoRest
    End

    // Connect to Facebook and send the following GET request:

    // GET /v2.7/me HTTP/1.1
    // Host: graph.facebook.com
    Move True To iBAutoReconnect
    Get ComConnect Of hoRest "graph.facebook.com" 443 True iBAutoReconnect To iSuccess
    If (iSuccess <> True) Begin
        Get ComLastErrorText Of hoRest To sTemp1
        Showln sTemp1
        Procedure_Return
    End

    // Provide the authentication credentials (i.e. the access key)
    Get pvComObject of hoOauth2 to vOauth2
    Get ComSetAuthOAuth2 Of hoRest vOauth2 To iSuccess

    Get ComFullRequestNoBody Of hoRest "GET" "/v2.7/me" To sResponseJson
    Get ComLastMethodSuccess Of hoRest To bTemp1
    If (bTemp1 <> True) Begin
        Get ComLastErrorText Of hoRest To sTemp1
        Showln sTemp1
        Procedure_Return
    End

    Showln sResponseJson

    // The responseJson looks like this:
    // {"name":"John Doe","id":"10111011320111110"}
