## How to Integrate Helicone with PostHog

<Steps>
  <Step title="Sign up for PostHog">
    Create an account for PostHog [here](https://posthog.com/).
  </Step>
  <Step title="Add two new headers">
    Similar to how you set `Helicone-Auth` [header](https://docs.helicone.ai/getting-started/integration-method/openai-proxy#openai-v1), add two new headers `Helicone-Posthog-Key` and `Helicone-Posthog-Host` with your API key and PostHog host.
    <Tip>You can find both your API key and PostHog host in your [PostHog project settings](https://us.posthog.com/settings/project). </Tip>
