1.1 Workflow description

Title: Monitor SSL certificate of any domain with uProc
Workflow name: Monitor SSL certificate of any domain with uProc

Do you want to check the SSL certificate expiration dates of your customers or servers?

This workflow gets information of an SSL certificate using the uProc Get Certificate by domain tool. You can use this workflow to query SSL certificates in bulk and send alarms when any certificate has expired.

You need to add your credentials (Email and API Key - real -) located at Integration section to n8n.

You can replace "Create Domain Item" with any integration containing a domain, like Google Sheets, MySQL, or Zabbix server.

Every "uProc" node returns the next fields per every analyzed SSL certificate:

issuer: Contains the issuer.
provider: Contains the provider.
valid_from: Contains the start date.
valid_to: Contains the end date.
serial_number: Contains the serial number.
type: Contains if supports one or multiple domains.
protocol: Contains the protocol.
valid: Contains its validity.
domains: Contains all domains and subdomains supported.

An "IF" node detects if the certificate is valid or not.

Finally, the workflow sends an alarm to a Telegram channel to know if the certificate has expired.

4. Reproducing the Workflow from Scratch

1. Download the workflow JSON

Use the JSON export at /data/workflows/861/861.json as the source template for this automation.
2. Import the template into n8n

Open n8n, import the downloaded JSON, and review each node before activating the workflow.
3. Configure credentials and variables

Replace placeholder credentials, API keys, webhook URLs, account IDs, and environment-specific values with your own settings.
4. Test with sample data

Run the workflow manually or in a staging workspace, inspect node output, and confirm downstream systems receive the expected data.
5. Activate and monitor

Enable the workflow only after testing, then monitor executions, errors, and rate limits during the first production runs.

5. General Notes & Resources

Review imported nodes carefully before activation. This catalog entry is intended to help you inspect the workflow structure, understand required services, and find related templates faster.

Node names, credentials, schedules, webhook paths, and external service limits may need adjustment for your workspace.

Generate incident response reports with Supabase, Gemini and Claude

## Quick Overview This workflow ingests incident and playbook content from GitHub into Supabase (including pgvector embeddings with Google Gemini) and, on a webhook trigger, enriches a test incident with historical matches, a routed response playbook, and live web threat intel (via Tavily + OpenRouter) to generate a validated incident response report. ## How it works 1. Receives a POST webhook containing the incident payload (including an encrypted OpenRouter API key) and decrypts the key for downstream LLM calls. 2. Creates a tracking row in a Supabase table and loads configuration values used by the retrieval and report-generation steps. 3. Retrieves similar resolved incidents from a Supabase pgvector store using Google Gemini embeddings and returns structured historical patterns. 4. Retrieves the best-matching reference playbook from a Supabase pgvector store and fetches the full playbook text from Supabase, falling back to a built-in generic playbook when no match is found. 5. Uses Tavily Search plus an OpenRouter-backed agent to gather external threat intelligence, IOCs, and phased mitigation guidance when the incident is classified as security-relevant. 6. Merges the three intelligence branches and uses an OpenRouter LLM to synthesize a structured JSON output and an 11-section Markdown incident response report. 7. Validates that required report fields exist and, if valid, writes the structured output and Markdown report back to the Supabase test incident record; otherwise it skips the write. ## Setup 1. Create Supabase tables for test incidents and vector stores (for resolved incidents and reference playbooks) and configure the matching SQL functions used for retrieval (for example, `match_resolved_incidents_v1` and `match_reference_playbooks_v1`). 2. Add Supabase credentials in n8n and set the correct table names and query function names in the workflow’s configuration nodes. 3. Add Google Gemini (PaLM) API credentials and ensure the embedding model name used in the config (for example, `models/gemini-embedding-001`) is available to your account. 4. Add an OpenRouter API credential for the chat models used by the agents and synthesizer, and ensure your webhook caller sends an `encrypted_openrouter_key` value that matches the workflow’s decryption format. 5. Add a Tavily API credential for web search, then copy the webhook URL and configure your incident source to POST the incident JSON to it.

Check JWT security of API endpoints with HTTP requests and Google Sheets

## Quick Overview This workflow reads API endpoints and JWTs from Google Sheets, tests each endpoint with multiple token scenarios using HTTP requests, and writes a risk-scored security summary back to Google Sheets. ## How it works 1. Triggers manually (or on an optional daily schedule). 2. Loads the target Google Sheets document ID and the endpoint/results tab names. 3. Reads endpoint definitions from Google Sheets and keeps only rows marked as active. 4. For each endpoint, decodes the provided JWT and generates test variants (no auth, tampered payload, and alg:none). 5. Sends HTTP requests to the endpoint using the valid token and, if that succeeds, repeats the request with each test token variant and captures the response status codes. 6. Evaluates the status codes and token metadata to flag issues (for example, unauthenticated access, tampered token acceptance, alg:none acceptance, or missing exp) and assigns a risk level. 7. Appends the timestamped results and summary to the results tab in Google Sheets. ## Setup 1. Create a Google Sheet with an endpoints tab containing columns like `label`, `endpoint_url`, `method`, `token`, and `active`, and a results tab with columns like `timestamp`, `label`, `risk_level`, `t1_valid`, `t2_no_auth`, `t3_tampered`, `t4_alg_none`, and `summary`. 2. Add a Google Sheets Service Account credential in n8n and share the spreadsheet with the service account email. 3. Update the Sheet ID and tab names in the workflow’s variables (Sheet ID, endpoints sheet name, and results sheet name). 4. Ensure each endpoint row includes a valid JWT in the `token` column and set `active` to TRUE for endpoints you want to test. 5. If you want it to run automatically, enable the schedule trigger and adjust the cron expression as needed.

Monitor SSL certificate expiry with Google Sheets, Slack, Gmail and Jira

## Quick Overview This workflow runs daily to check SSL certificate expiry for domains listed in Google Sheets, using ssl-checker.io to fetch certificate details, then creating Jira issues and sending Slack and Gmail alerts for risky certificates while logging results and posting a daily Slack digest. ## How it works 1. Runs every day at 08:00 on a schedule trigger. 2. Reads the domain list from a Google Sheets “Domains” sheet and filters out blank rows or domains marked as disabled. 3. Processes domains one by one, calling the ssl-checker.io API to retrieve each site’s live SSL certificate details. 4. Calculates days remaining until expiry, assigns a status (Expired, Critical, Warning, Healthy, or Unknown), and flags items that require attention. 5. For certificates that need attention, creates a Jira task and sends an alert to Slack and an email via Gmail with the certificate details. 6. For healthy certificates, writes the latest check results to a Google Sheets “Log” sheet. 7. Aggregates all results from the run into a single summary message and posts the daily digest to Slack. ## Setup 1. Create a Google Sheet with a “Domains” sheet containing at least a `domain` column (and optionally an `enabled` column) and a “Log” sheet to store results, then add your Google Sheets credentials and set the spreadsheet ID. 2. Add an API key for ssl-checker.io (or a compatible SSL lookup endpoint) and place it in the HTTP Authorization header. 3. Add your Jira credentials and set the target project key for ticket creation. 4. Add your Slack credentials and set the channel ID used for alerts and the daily digest. 5. Add your Gmail credentials and set the recipient address for email alerts. 6. (Optional) Adjust the warning and critical thresholds (30 and 7 days) in the expiry calculation code if your policy differs.
