How to Integrate Helicone with PostHog

1

Sign up for PostHog

Create an account for PostHog here.

2

Add two new headers

Similar to how you set Helicone-Auth header, add two new headers Helicone-Posthog-Key and Helicone-Posthog-Host with your API key and PostHog host.

You can find both your API key and PostHog host in your PostHog project settings.

• Python
• Node.js
• Terminal

client = OpenAI(
	api_key="<your-api-key-here>", # Replace with your OpenAI API key
	base_url="https://oai.helicone.ai/v1" # Set the API endpoint
	default_headers= {
		"Helicone-Auth": f"Bearer {HELICONE_API_KEY}",
		"Helicone-Posthog-Key": "<ph_project_api_key>",
		"Helicone-Posthog-Host": "<ph_client_api_host>", # (Optional)
	}
)

Helicone events will now be exported into PostHog as soon as they’re available.
