## How it works

<Steps>
  <Step title="Get your API key">
    Every request is authenticated with an `X-API-Key` header scoped to your business account. Generate one from the Connectly Dashboard at any time.
  </Step>

  <Step title="Send your first message">
    Use the **template message endpoint** to initiate a conversation with a customer. Templates are pre-approved by Meta, so they can be sent at any time — no prior interaction needed.
  </Step>

  <Step title="Reply within the session window">
    Once a customer messages you back, a 24-hour window opens. During that window, use the **session message endpoint** to send free-form replies — no template required.
  </Step>

  <Step title="Listen for events via webhooks">
    Subscribe to Connectly webhooks to receive real-time events: delivery status updates, inbound customer messages, button clicks, and more.
  </Step>
</Steps>
