How do I monitor a Facebook group for new posts?

curl -G "https://api.socialapis.io/facebook/groups/posts" \
  --max-time 100 \
  --fail-with-body \
  -H "x-api-token: $SOCIALAPIS_API_KEY" \
  --data-urlencode "link=https://www.facebook.com/groups/gieldagryplanszowe" \
  --data-urlencode "limit=9"

import os

import requests

response = requests.get(
    "https://api.socialapis.io/facebook/groups/posts",
    headers={"x-api-token": os.environ["SOCIALAPIS_API_KEY"]},
    params={
        "link": "https://www.facebook.com/groups/gieldagryplanszowe",
        "limit": "9",
    },
    timeout=100,
)
response.raise_for_status()
print(response.json())

// Node 18+, as an ES module (e.g. main.mjs)
async function get(url, params) {
  const query = new URLSearchParams(params).toString();
  const response = await fetch(query ? `${url}?${query}` : url, {
