Run the Script:

python sync.py owner repo

Example

python sync.py openai gpt

sync.py

#!/usr/bin/env python3 import os import sys import requests

GITHUB_API = "https://api.github.com" POSTHOG_ENDPOINT = "/capture/"

def get_github_events(owner, repo, token): url = f"{GITHUB_API}/repos/{owner}/{repo}/events" headers = {"Authorization": f"Bearer {token}"} resp = requests.get(url, headers=headers) resp.raise_for_status() return resp.json()

def send_to_posthog(api_key, host, event_name, properties): url = f"{host}{POSTHOG_ENDPOINT}" payload = { "api_key": api_key, "event": event_name, "properties": properties, } resp = requests.post(url, json=payload) resp.raise_for_status() return resp.json()

def main(): if len(sys.argv) < 3: print("Usage: python sync.py ") sys.exit(1)

owner = sys.argv[1] repo = sys.argv[2]

github_token = os.getenv("GITHUB_TOKEN") posthog_key = os.getenv("POSTHOG_API_KEY") posthog_host = os.getenv("POSTHOG_HOST", "https://app.posthog.com")

if not github_token or not posthog_key: print("Missing environment variables. Please set GITHUB_TOKEN and POSTHOG_API_KEY.") sys.exit(1)

print(f"Fetching GitHub events for {owner}/{repo}...") events = get_github_events(owner, repo, github_token)

for ev in events: event_type = ev.get("type", "GitHubEvent") properties = { "repo": f"{owner}/{repo}", "id": ev.get("id"), "actor": ev.get("actor", {}).get("login"), "created_at": ev.get("created_at"), "raw": ev, }

print(f"Sending event: {event_type} ...") send_to_posthog(posthog_key, posthog_host, event_type, properties)

print("Sync complete!")
