# Start a meeting for a non-logged in or API user

<!-- WARNING: THIS FILE WAS AUTOGENERATED! DO NOT EDIT! -->

> The code on this page works with either the **default UI** or the **custom UI**.

After getting the [Zoom Access Key (ZAK) token](/docs/api/users/#tag/users/get/users/me/zak), pass it to start meetings with either a meeting number or a vanity ID.

## Start with a meeting number

To start a meeting with meeting number, first get a `ZoomSDKMeetingService` instance from `ZoomSDK`.

```swift
guard let meetingService = ZoomSDK.shared().getMeetingService() else { return }
```

```objectivec
ZoomSDKMeetingService *meetingService = [[ZoomSDK sharedSDK] getMeetingService];
if (!meetingService) {
    return;
}
```

Then, prepare `ZoomSDKStartMeetingUseZakElements`.

```swift
let params = ZoomSDKStartMeetingUseZakElements()
```

```objectivec
ZoomSDKStartMeetingUseZakElements *params = [[ZoomSDKStartMeetingUseZakElements alloc] init];
```

Store the Zoom Access Key (`zak`), display name, and meeting number in the `ZoomSDKStartMeetingUseZakElements` instance, and start the meeting by calling `startMeetingWithZAK` method.

```swift
params.userType = SDKUserType_APIUser // SDKUserType class
params.zak = "ZAK" // ZAK of the local user
params.displayName = "DISPLAY_NAME"
params.meetingNumber = 123456789
let result = meetingService.startMeeting(withZAK: params)
```

```objectivec
params.userType = SDKUserType_APIUser;
params.zak = @"ZAK"; // ZAK of the local user
params.displayName = @"DISPLAY_NAME";
params.meetingNumber = 123456789;
ZoomSDKError result = [meetingService startMeetingWithZAK:params];
```

## Start with a vanity ID

A **vanity ID** is a special and personalized ID that uniquely belongs to a user.

To start a meeting with a vanity ID, the process is almost the same as starting a meeting with a meeting number. Just store the `vanityID` inside the `ZoomSDKStartMeetingUseZakElements` instance instead of the `meetingNumber`.

```swift
params.userType = SDKUserType_APIUser // SDKUserType class
params.zak = "ZAK" // ZAK of the local user
params.displayName = "DISPLAY_NAME"
params.vanityID = "123456789"
let result = meetingService.startMeeting(withZAK: params)
```

```objectivec
params.userType = SDKUserType_APIUser;
params.zak = @"ZAK"; // ZAK of the local user
params.displayName = @"DISPLAY_NAME";
params.vanityID = @"123456789";
ZoomSDKError result = [meetingService startMeetingWithZAK:params];
```

## Start meeting status

To know whether the start meeting action succeeded, didn't succeed, or resulted in an error, listen to the `onMeetingStatusChange` callback under `ZoomSDKMeetingServiceDelegate`.

```swift
guard let meetingService = ZoomSDK.shared().getMeetingService() else { return }
meetingService.delegate = self

extension ViewController: ZoomSDKMeetingServiceDelegate {
    func onMeetingStatusChange(_ state: ZoomSDKMeetingStatus, meetingError error: ZoomSDKMeetingError, end reason: EndMeetingReason) {

    }
}
```

```objectivec
// In your .h file
@interface TestWindow : NSWindowController <ZoomSDKMeetingServiceDelegate> {

}

// In your .m file
ZoomSDKMeetingService *meetingService = [[ZoomSDK sharedSDK] getMeetingService];
if (!meetingService) {
    return;
}

meetingService.delegate = self;

- (void)onMeetingStatusChange:(ZoomSDKMeetingStatus)state meetingError:(ZoomSDKMeetingError)error EndReason:(EndMeetingReason)reason {

}
```
