# Enqueuing Calls

Use the call queue API to let users add themselves to a call queue — whether for onboarding, support, or any moment when they want to speak with your team.

<CodeGroup>
  ```swift Swift theme={null}
  UserKit.shared.enqueue(reason: "Onboarding", preferredCallTime: "Today")
  ```

  ```objc Objective-C theme={null}
  [[UserKit sharedInstance] enqueueWithReason:@"Onboarding" preferredCallTime:@"Today"];
  ```
</CodeGroup>

Each time a user is added to the call queue, UserKit automatically sends an email notification to your team.
