# Update Settings

> Configure settings for your Facebook Private Group Posts Scraper squid

Update the configuration of your **Facebook Private Group Posts Scraper** squid. Pass crawler-specific settings inside the `params` object.

## Headers

<ParamField header="Authorization" type="string" required>
  Your API authentication token. Value: `Token YOUR_API_KEY`
</ParamField>

<ParamField header="Content-Type" type="string" required>
  Must be application/json. Value: `application/json`
</ParamField>

## Body

<ParamField body="params" type="object">
  Crawler-specific settings. See fields below.
</ParamField>

## Settings Fields

<ParamField body="params.fetch_since" type="string">
  Only collect posts published after this point. Use a relative duration (e.g. `"24h"`, `"7d"`, `"2w"`) or an absolute date (`YYYY-MM-DD`).
</ParamField>

<ParamField body="params.fetch_since_timezone" type="string">
  Timezone for interpreting an absolute `fetch_since` date (e.g. `"Europe/Paris"`). Only applies when `fetch_since` is an absolute date — ignored for relative values like `"24h"` or `"7d"`.
</ParamField>

<Tip>
  Set `fetch_since` to `null` to collect all posts, or use a relative duration (`"24h"`, `"7d"`, `"2w"`) or absolute date (`YYYY-MM-DD`) to collect only recent posts. When using an absolute date, set `fetch_since_timezone` to interpret it in the correct timezone (e.g. `"Europe/Paris"`).
</Tip>

## Code Examples

  ```bash cURL theme={null}
  curl -X POST "https://api.lobstr.io/v1/squids/YOUR_SQUID_HASH" \
    -H "Authorization: Token YOUR_API_KEY" \
    -H "Content-Type: application/json" \
    -d '{
      "name": "Facebook Private Group Posts",
      "params": {
        "fetch_since": "7d",
        "fetch_since_timezone": null
      }
    }'
  ```

  ```python Python theme={null}
  import requests

  API_KEY = "YOUR_API_KEY"
  BASE_URL = "https://api.lobstr.io/v1"
  headers = {"Authorization": f"Token {API_KEY}"}

  squid_hash = "YOUR_SQUID_HASH"

  response = requests.post(f"{BASE_URL}/squids/{squid_hash}",
      headers=headers,
      json={
          "name": "Facebook Private Group Posts",
          "params": {
              "fetch_since": "7d",  # relative: "24h", "7d", "2w" | absolute: "2026-01-01"
              "fetch_since_timezone": None  # e.g. "Europe/Paris" — only used with absolute fetch_since
          }
      }
  )

  data = response.json()
  print(f"Squid updated: {data['name']}")
