## Get Started in 3 Steps

<Steps>
  <Step title="Get your API credentials">
    Log into your Convo dashboard, navigate to **Settings**, and copy your Project API Password (`X-API-WA-Project-API-Pwd`). You'll use this header on every API call.
  </Step>

  <Step title="Create or find your Project ID">
    Every WhatsApp number on Convo is associated with a **Project**. Find your Project ID in the dashboard — it's required as a path parameter for most API calls.
  </Step>

  <Step title="Send your first message">
    Call `POST /project/{project_id}/messages` with a recipient phone number and a text body. See the [Quick Start guide](/quickstart) for a complete working example.
  </Step>
</Steps>

<Note>
  Convo operates on top of the WhatsApp Business Platform. All outbound messages to users who haven't messaged you first must use an approved **Message Template**. See [Templates](/concepts/templates) for details.
