What this template does Transforms provider documentation (URLs) into an auditable, enforceable multicloud security control baseline. It: Fetches and sanitizes HTML Uses AI to extract security requirements (strict 3-line TXT blocks) Composes enforceable controls** (strict 7-line TXT blocks with true-equivalence consolidation) Builds the final baseline* (TXT or JSON, see *Outputs) with a Technology: header Returns a downloadable artifact via webhook and can append/create the file in Google Drive Why it’s useful Eliminates manual copy-paste and produces a consistent, portable baseline ready for review, audit, or enforcement tooling—ideal for rapidly generating or refreshing baselines across cloud providers and services. Multicloud support The workflow is multicloud by design. Provide the target cloud in the request and run the same pipeline for: AWS, **Azure, GCP (out of the box) Extensible to other providers/services by adjusting prompts and routing logic How it works (high level) POST /create (Basic Auth) with { cloudProvider, technology, urls[] } Input validation → generate uuid → resolve Google Drive folder (search-or-create) Download & sanitize each URL AI pipeline: Extractor → Composer → Baseline Builder → (optional) Baseline Auditor Append/create file in Drive and return a downloadable artifact (TXT/JSON) via webhook Request (webhook) Method: POST URL: https://<your-n8n>/webhook/create Auth: Basic Auth Headers: Content-Type: application/json Example input (Postman/CLI) { "cloudProvider": "aws", "technology": "Amazon S3", "urls": [ "https://docs.aws.amazon.com/AmazonS3/latest/userguide/security-best-practices.html", "https://www.trendmicro.com/cloudoneconformity/knowledge-base/aws/S3/", "https://repost.aws/knowledge-center/secure-s3-resources" ] } Field reference cloudProvider (string, required) — case-insensitive. Supported: aws, azure, gcp. technology (string, required) — e.g., "Amazon S3", "Azure Storage", "Google Cloud Storage". urls (string\[], required) — 1–20 http(s) URLs (official/reputable docs). Optional (Google Drive destination): gdriveTargetId (string) — Google Drive folderId used for append/create. gdrivePath (string) — Path like "DefySec/Baselines" (folders are created if missing). gdriveTargetName (string) — Folder name to find/create under root. Optional (Assistant overrides): assistantExtractorId, assistantComposerId, assistantBaselineId, assistantAuditorId (strings) Resolution precedence Drive: gdriveTargetId → gdrivePath → gdriveTargetName → default folder. Assistants: explicit IDs above → dynamic resolution by name (expects 1_DefySec_Extractor, 2_DefySec_Control_Composer, 3_DefySec Baseline Builder, 4_DefySec_Baseline_Auditor). Validation Rejects empty urls or non-http(s) schemes; normalizes cloudProvider to aws|azure|gcp. Sanitizes fetched HTML (removes scripts/styles/headers) before AI steps. Outputs Primary:* downloadable *TXT** file controls_<technology>_<timestamp>.txt (via webhook). Composer outcomes:** if no groups to consolidate → NO_CONTROLS_TO_BE_CONSOLIDATED; if nothing valid remains → NO_CONTROLS_FOUND.  JSON path:* when the Builder stage is configured for *JSON-only** output (strict schema), the workflow returns a .json artifact and the Auditor validates it (see next section).  Techniques used (from the built-in assistants) Provider-aware extraction with strict TXT contract (3 lines):* Extractor limits itself to the declared provider/technology, outputs only Description/Reference/SecurityObjective, and applies a *reflexive quality check** before emitting.  Normalization & strict header parsing:** Composer normalizes whitespace/fences, requires the CloudProvider/Technology header, and ignores anything outside the exact 3-line block shape.  True-equivalence grouping & consolidation:* Composer groups *only** when intent, enforcement locus/mechanism, scope, and mode/setting all match—otherwise items remain distinct.  7-line enforceable control format:* Composer renders each (consolidated or unique) control in *exactly seven labeled lines** to keep results auditable and automatable.  Builder with JSON-only schema & technology inference:* Builder parses 7-line blocks, infers technology, consolidates true equivalents again if needed, and returns *pure JSON** matching a canonical schema (with counters in meta).  Self-evaluation loop (Auditor):* Auditor *unwraps transport, validates **schema & content, checks provider terminology/scope/automation, and returns either GOOD_ENOUGH or a JSON instruction set for the Builder to fix and re-emit—enabling reflective improvement.  Reference prioritization:** Across stages, official provider documentation is preferred in References (AWS/Azure/GCP).  Customization & extensions Prompt-reflective techniques:** keep (or extend) the Auditor loop to add more review passes and quality gates.  Compliance assistants:* add assistants to analyze/label controls for *HIPAA, PCI DSS, SOX** (and others), emitting mappings, gaps, and remediation notes. Implementation context:* feed internal implementation docs, runbooks, or *Architecture Decision Records (ADRs); use these as **grounding to generate or refine controls (works with local/self-hosted LLMs, too). Local/self-hosted LLMs:** swap OpenAI nodes for your on-prem LLM endpoint while keeping the pipeline. Provider-specific outputs:** extend the final stage to export Policy-as-Code or IaC snippets (Rego/Sentinel, CloudFormation Guard, Bicep/ARM, Terraform validations). Assistant configuration & prompts Full assistant configurations and prompts (Extractor, Composer, Baseline Builder, Baseline Auditor) are available here: https://github.com/followdrabbit/n8nlabs/tree/main/Lab03%20-%20Multicloud%20AI%20Security%20Control%20Baseline%20Builder/Assistants Security & privacy No hardcoded secrets in HTTP nodes; use n8n’s Credential Manager.

How It Works A webhook or timer triggers the workflow to automatically fetch inventory data from multiple platforms. Stock levels are compared across stores to identify discrepancies, and any inconsistencies are updated on the respective platforms in real time. All changes and updates are recorded in Google Sheets for easy tracking, and email alerts are sent to notify relevant team members of any exceptions or issues that require attention. This ensures inventory accuracy and timely response to stock mismatches. Setup Steps Add Shopify and/or WooCommerce API credentials to enable secure data access. Connect Google Sheets for comprehensive logging of all inventory updates and Gmail for sending timely email alerts. Configure the sync frequency within the Function nodes to control how often inventory data is fetched, compared, and updated. Prerequisites Shopify/WooCommerce API keys Google Sheets access Gmail credentials n8n instance Customization Add ERPNext or custom APIs Enable Slack notifications AI discrepancy detection Benefits Real-time inventory accuracy Automated cross-platform updates Centralized audit logging

iOS Environment Config Sync Wizard: .env to Xcode This workflow automatically detects changes to .env.staging files, compares them against iOS Xcode configuration files, creates pull requests to sync values, and invalidates Xcode build caches when needed. It ensures consistency between environment files and iOS project configs while automating the propagation of changes across the codebase and notifying the team via email. Quick Implementation Steps Import the workflow JSON into your n8n instance Set up credentials for GitHub and email Configure the webhook URL in your Git repository Customize configuration parameters in the "Set Configuration" node Activate the workflow What It Does The Environment Config Sync for iOS Xcode Projects workflow is designed to maintain consistency between environment configuration files and iOS project configuration files. When changes are made to .env.staging, the workflow automatically detects these changes, determines which iOS configuration files need to be updated, creates a new branch with those updates, and opens a pull request for review. The workflow analyzes the differences between the environment file and iOS configs, identifies which values need to be synchronized, and applies these changes to the appropriate files. It also checks if any of the changed values require cache invalidation and handles this automatically. Finally, it sends a detailed email notification to the iOS team with information about the sync operation. This automation reduces manual work, ensures consistency between configuration files, and helps prevent issues caused by mismatched environment settings across different parts of the iOS build system. Who's It For This workflow is ideal for: iOS development teams managing environment-specific configurations DevOps engineers responsible for maintaining Xcode project configuration consistency Mobile app developers working with multiple environment configurations Teams implementing CI/CD best practices for iOS applications Organizations using environment files to manage build-time configurations for Xcode projects Requirements n8n instance (self-hosted or cloud) GitHub repository with iOS project files Email service (SMTP) for sending notifications .env.staging file or similar environment configuration file iOS configuration files (Info.plist, Config.xcconfig, etc.) How It Works Webhook Trigger: The workflow starts when a push event occurs in the GitHub repository Configuration Setup: Sets up configurable parameters for file paths, branches, and notification settings File Change Detection: Checks if the .env.staging file was modified in the push Config Diff Analysis: Compares the .env.staging file with iOS Xcode configurations to identify differences Branch Creation: Creates a unique branch name and creates a new branch in the repository File Update Preparation: Prepares the updated content for each configuration file File Updates: Updates each configuration file in the new branch with the synced values PR Creation: Creates a pull request with all the configuration changes Cache Invalidation: Invalidates Xcode build cache if necessary based on changed keys Email Notification: Sends a detailed email notification about the completed sync operation How To Set Up Steps to Configure and Use 1\. Import the Workflow Import the provided JSON file into your n8n instance 2\. Set Up Credentials GitHub**: Create a new credential with a GitHub personal access token with repo scope Email**: Create a new credential with your SMTP server details for sending emails 3\.

Configure Email Settings In the "Send Email Notification" node, update the "fromEmail" parameter to match your sending email address Ensure your SMTP credentials are properly configured in n8n 6\. Activate the Workflow Once all configurations are complete, activate the workflow Test by making a change to your .env.staging file and pushing it to the repository How To Customize Add More Config Files**: Update the configFiles parameter in the "Set Configuration" node to include additional iOS configuration files like .xcconfig files or project.pbxproj Modify Cache Invalidation Logic**: Update the cacheInvalidationKeys parameter to change which keys trigger cache invalidation Customize PR Content**: Edit the "Create PR" node to modify the PR title, body, or labels Change Email Notifications**: Update the "Send Email Notification" node to modify the email format, subject, or add additional recipients Implement Actual Cache Invalidation**: Modify the "Invalidate Cache" node to implement actual Xcode cache invalidation logic for your CI/CD system Add More Environment Files**: Extend the workflow to monitor additional environment files beyond .env.staging Add‑ons Multi-Environment Support: Extend the workflow to handle multiple environment files (.env.development, .env.production) with different target branches and configurations Configuration Validation: Add validation steps to ensure that environment values match expected formats or patterns before creating PRs Automated PR Merging: Add logic to automatically merge PRs if all checks pass and no conflicts are detected Configuration History Dashboard: Integrate with a database to track configuration changes over time and provide analytics Team Approval Workflow: Add approval steps that require team members to review and approve configuration changes before PRs are created Use Case Examples API Key Rotation: When security policies require rotating API keys, the workflow automatically updates all iOS configuration files with the new keys and invalidates the Xcode build cache to ensure the changes take effect immediately. Environment Promotion: When promoting configurations from staging to production, the workflow ensures that all iOS project files are consistently updated across the codebase, preventing deployment issues caused by mismatched configurations. Bundle Version Updates: When updating bundle versions in .env.staging for a new App Store release, the workflow automatically updates version strings in Info.plist files, ensuring version consistency for App Store submission. Feature Flag Management: When feature flags are added or modified in .env.staging, the workflow propagates these changes to Config.xcconfig files, ensuring that feature flags are consistently available throughout the iOS application. Multi-Target Projects: In projects with multiple iOS targets (e.g., app, extension, watchOS), the workflow can be extended to update configuration files across all targets when environment variables change, ensuring consistency throughout the application ecosystem.

What is this? This workflow is a Lead Qualification Voice Agent automation template built in n8n. It automates the process of qualifying leads by initiating outbound calls, analyzing call transcripts, updating lead data, and sending follow-up emails. The workflow integrates Google Sheets, OpenAI, and Twilio (via ElevenLabs API) to streamline lead management for sales or customer success teams. 1. Initiate Call Purpose: This step starts the lead qualification process by detecting new leads and preparing to contact them. How it works: The workflow is triggered when a new lead is added to your data source (such as a new row in Google Sheets, using the “Google Sheets Trigger” node). The trigger node captures essential lead information (e.g., name, phone number, service of interest) from the new entry. The workflow then prepares a personalized call script or opener, often using an AI node (like OpenAI) to generate a friendly and relevant introduction based on the lead’s details. An outbound call is initiated to the lead’s phone number using a telephony integration node (such as HTTP Request to ElevenLabs or Twilio). Note: Ensure your trigger node is correctly set up to monitor the right data source and columns. Configure the telephony node with valid API credentials and the correct phone number field. Optionally, customize the AI prompt to tailor the call opener to your business context. 2. Fetch Client Data Purpose: This step retrieves detailed information about the lead from your data source (such as a CRM, database, or Google Sheets). How it works: The workflow uses a data retrieval node (such as Google Sheets, HTTP Request, or a database node) to fetch client details based on a unique identifier (like phone number or email) captured in the trigger step. The node is configured to query the data source for all relevant fields, such as the lead’s name, company, previous interactions, and any custom attributes important for your qualification process. The fetched data is then made available to subsequent nodes, allowing for dynamic personalization of the call script and follow-up actions. Note: Ensure your data source is up-to-date and contains all necessary fields for lead qualification. 3. Outbound Call Processing Purpose: To manage the workflow after the outbound call is initiated, including handling call results, analyzing transcripts, and updating lead status. How it works: After the call is placed (using a telephony integration node), the workflow waits for the call to complete. This can be achieved using a webhook node (if your provider supports callbacks) or a polling node to check call status. Once the call is finished, the workflow retrieves the call outcome (e.g., answered, voicemail, failed) and, if available, the call transcript. The transcript can be sent to an AI node (like OpenAI) for analysis—such as extracting intent, sentiment, or key information discussed during the call. Based on the analysis, the workflow updates the lead’s status in your data source (e.g., marking as “Qualified,” “Needs Follow-up,” or “Unreachable”). Optionally, the workflow can trigger additional actions, such as sending a follow-up email, notifying a sales rep, or logging the interaction in your CRM. Note: Use webhook nodes for real-time call result processing if your telephony provider supports it. Log all call results and analysis for future reference and reporting. Prerequisities OpenAI Google Sheets Twilio Elevenlabs: Import the twilio number into Elevenlabs Set up an agent in Elevenlabs Set up prompt into Elevenlabs Set up webhooks for fetch client initiation data and post call data Customization Change Data Source: Swap the Google Sheets node for another data source (e.g., Airtable, MySQL) as needed. Modify Call Script: Edit the OpenAI prompt to generate different call openers or scripts based on your use case. Adjust Call Logic: Modify the outbound call node to use a different telephony provider or to handle call scheduling. Notification Options: Integrate with email, chat, or notification services to alert your team of qualified leads.

Who's it for This workflow is perfect for digital marketing agencies, sales teams, and business development professionals who want to automate lead qualification, scoring, and personalized outreach.

Manually creating invoice in Word takes 25 minutes including calculation checks, formatting fixes, and finding bank details. Client expects invoice same day to process Monday payment. Solution: Designer clicks "Invoice Now" button in project management tool which triggers webhook. Workflow validates project details, generates branded invoice with itemized design services, converts to PDF, emails to client, and saves to Drive. Designer receives Slack notification confirming invoice sent. Result: Invoice delivered in 45 seconds instead of 25 minutes. Client receives professional invoice within 2 minutes of project completion. Designer saves 24 minutes and impresses client with speed. Payment received Monday morning. Over 50 projects annually, saves 20+ hours and increases cash flow by receiving payments 2-3 days faster. Annual impact: $3,500 in saved time plus faster payment collection. SaaS Startup Example SaaS company with 250 subscription customers needs monthly invoices. Finance manager manually creates invoices in spreadsheet, exports to PDF, and emails individually. Process takes 2 full days monthly causing invoice delivery delays. Solution: Connects workflow to Stripe subscription billing. When subscription renews, Stripe webhook triggers invoice generation. Customer name, email, subscription tier, and amount flow automatically. Invoice generates with payment link back to Stripe customer portal. Result: All 250 invoices delivered automatically on billing date. Zero manual work required. Customers receive invoices instantly with one-click payment links. Subscription payment collection improves from 85% to 96% in first week. Finance manager reallocates 2 days monthly to strategic analysis. Annual impact: saves 192 hours ($9,600 value) plus $18,000 additional revenue from improved collection rates. Marketing Agency Example Agency invoices 35 retainer clients on 1st of month. Account managers manually compile billable hours, adjust for change orders, calculate totals, and send invoices. Inconsistent formatting causes client confusion and payment delays. Solution: Time tracking system triggers webhook on last day of month with billable hours per client. Workflow generates consistent invoices with itemized service breakdown (social media hours, content creation, ad spend, strategy consulting). Each client receives branded invoice with their specific services. Result: All 35 invoices generated and delivered by 8 AM on 1st of month. 100% brand consistency across all invoices. Client questions reduce by 70% due to clear itemization. Payment speed increases - average collection time drops from 38 days to 24 days. Annual impact: saves 30 hours monthly ($18,000 annually) plus $85,000 improved cash flow from faster collections. Web Development Studio Example Studio completes 12-15 client projects monthly. Invoicing delayed until projects 100% complete causes cash flow gaps. Manually creating milestone invoices for larger projects creates accounting burden. Solution: Project management system triggers invoice on milestone completion (50% deposit, 75% progress payment, final 25%). Workflow automatically generates invoice for milestone amount with reference to project scope and completion percentage. Result: Cash flow improves dramatically with milestone billing. Studio receives payments throughout project instead of only at end. Clients appreciate transparency of milestone invoicing. Payment disputes reduce by 85% since expectations clear. Annual impact: improved cash flow worth $145,000 in working capital plus 40 hours monthly saved (20,000 dollar annual value). Healthcare Clinic Example Medical practice sends 200+ patient invoices monthly for services not covered by insurance. Billing staff manually creates invoices in practice management system, exports to PDF, and mails or emails. Process error-prone and time-consuming. Solution: Integrates workflow with electronic health records (EHR). When service marked as patient-pay, webhook triggers invoice generation with CPT codes, service descriptions, and amounts. Invoice includes payment plan options and online payment link. Result: Invoices sent same day as service instead of 5-7 days later. Patients receive clear, itemized invoices with multiple payment options. Online payment adoption increases from 15% to 62%. Collection rate improves from 73% to 89%. Billing staff reallocates time to insurance follow-up and patient support. Annual impact: saves 25 hours monthly ($15,000 annually) plus $78,000 additional collections.
