1.1 Workflow description

Title: Detect and enforce abuse cases with OpenAI, Slack, Gmail and Sheets
Workflow name: Detect and enforce abuse cases with OpenAI, Slack, Gmail and Sheets

How It Works

This workflow automates platform trust and safety operations by deploying a multi-agent AI system that detects abuse signals, investigates behaviour, scores risk, checks policy compliance, and enforces actions automatically. Designed for platform safety teams, content moderation managers, and compliance officers, it eliminates manual triage delays and ensures high-severity violations are actioned immediately. An abuse signal webhook triggers behaviour analysis via OpenAI, classifying signals by severity. A routing node directs cases to a Governance Agent, which orchestrates Investigation, Risk Scoring, and Policy Compliance Checker sub-agents. Enforcement data is prepared, then routed by action type-logging to abuse records, alerting the security team via Slack, sending escalation emails, or triggering auto-enforcement actions based on threshold checks—before all outcomes are logged.

Setup Steps

Configure Abuse Signal Webhook URL and authenticate incoming POST requests.
Add OpenAI API credentials to all OpenAI Model nodes.
Connect Google Sheets for abuse records and enforcement action logging.
Configure Slack credentials and set security team alert channel.
Add Gmail/SMTP credentials to Send Escalation Email node.

Prerequisites

Slack workspace with bot token
Gmail or SMTP credentials
Google Sheets for abuse and enforcement logging

Use Cases

Real-time abuse detection and auto-suspension on social platforms

Customization

Replace OpenAI with Anthropic Claude or NVIDIA NIM models

Benefits

Eliminates manual abuse triage with real-time AI signal processing

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.
