## Integration Flows

Choose the flow that matches your use case:

<CardGroup cols={2}>
  <Card title="Call single number" icon="user" href="/ai-integration/call-single">
    Initiate AI calls to a single phone number.

    Use this if the single call is meant to be automated based on user actions (like a sign-up or a form submission).

    **Best for**: Real-time automated responses, lead follow-ups, and 2FA/verification alerts.
  </Card>

  <Card title="Call bulk numbers" icon="users" href="/ai-integration/call-bulk">
    Dispatches AI calls to a list of several phone numbers via campaigns.

    This focuses on the business value of reaching a large audience simultaneously.

    **Best for**: High-volume marketing campaigns, mass announcements, and scheduled outreach to lead lists.
