A webhook call\u2014ideal for a button in your portal or a scheduled external ping\u2014fires the flow. The Code node supplies a curated list of certification-body URLs. ScrapeGraphAI then pulls the latest requirement text, effective date and version from each site. After a quick normalisation pass the results are bundled into one JSON payload and compared to the last stored copy in a GitLab repo. If even a single requirement changed, the IF node steers execution down the alert path: a Rocket.Chat message posts the diff and GitLab receives a commit containing the new canonical file. If nothing changed, the workflow simply answers the webhook with a 200 and the current data.\n\n## Setup steps\n\n1. Add ScrapeGraphAI credentials in n8n\n2. Fill the Code node with your certification URLs\n3. Create or select a GitLab project and set repo access credentials\n4. Configure a file path and branch in both GitLab nodes\n5. Add Rocket.Chat API credentials and channel name\n6. Deploy the webhook URL where your scheduler can reach it\n7. Enable the workflow and trigger a test run"

The **Incoming Webhook** waits for any POST call\u2014this keeps the workflow decoupled from specific schedulers or front-end apps. Immediately after, the **Prepare Certification URLs** Code node outputs one item per website you want to monitor. Keeping the list in code lets you version-control URLs and dynamically alter them without editing every downstream node. Because each item travels independently in n8n, a dedicated **item** is produced for every certification authority, making the subsequent ScrapeGraphAI execution perfectly parallel-friendly. Finally, no API keys appear here; the only configuration you need is to paste your target URLs and perhaps add headers if individual sites require special cookies or tokens."

For every incoming URL it receives from the previous step, the node uses its LLM-backed engine to locate and extract a **certification name**, a **requirement text**, and the **last-updated date**. The natural-language prompt instructs the AI to respond in a strict JSON schema so the workflow never breaks if the HTML layout shifts. Immediately downstream, the **Normalize Requirement Data** Code node polishes field names, converts dates to ISO-8601, and adds a hash we later use for quick diffing. This means any cosmetic spacing change in the requirement text will be detected as an actual update, guaranteeing that subscribers are never left with stale information."

Right after aggregation, a GitLab node fetches `requirements.json` from your repository\u2014this is the baseline the workflow compares against. Both the freshly scraped data and the stored baseline feed into a Merge node so that the next Code node can access them side-by-side.

It performs a deep comparison by stringifying each object and checking for mismatches. A boolean flag `changed` plus a trimmed `diff` object travel forward. The **Requirements Changed?** IF node then provides the mandatory conditional branching pattern: `true` leads to alerting and file update, `false` short-circuits directly to the webhook response. Structuring logic this way prevents unnecessary GitLab commits and Rocket.Chat noise, saving API resources and avoiding alert fatigue for your users."

Second, the **Update GitLab Record** node commits the new `requirements.json` to your repo with a clear commit message so the change becomes part of your long-term audit trail. Both branches eventually rejoin at **Respond to Webhook**, which returns a 200 status plus a summary object.
