## Onboarding Steps

<Steps>
  <Step title="Generate your Omnisend API key">
    <Note>
      An **Omnisend API key** is a unique credential generated in your Omnisend account that allows Upstack Data to securely access and interact with your Omnisend data. It is a long alphanumeric string, typically structured as a 64-character secret followed by a `-` and a short identifier (for example, `xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx-xxxxxxxxxx`).
