Comprehensive Customer Support with OpenAI O3 & GPT-41-Mini Multi-Agent Team

This n8n workflow demonstrates a multi-agent AI system designed for advanced customer support. It leverages LangChain agents and OpenAI models to process incoming chat messages, strategize responses, and potentially interact with various tools (though no specific tools are defined in this simplified version). The workflow aims to provide a sophisticated, AI-driven approach to handling customer inquiries.

What it does

Listens for Chat Messages: The workflow is triggered by incoming chat messages, acting as the entry point for customer inquiries.
Initial AI Agent Processing: An "AI Agent" node receives the chat message and initiates a thought process, likely to understand the user's intent and determine the best course of action.
Language Model Interaction: An "OpenAI Chat Model" is used by the AI Agent to process natural language, generate responses, and contribute to the decision-making process.
Strategic Thinking (Tool): A "Think Tool" is employed, suggesting that the AI agent will engage in a strategic thinking phase to plan its response or next steps.
Agent Tool Execution: An "AI Agent Tool" is present, indicating that the AI agent can utilize specific tools (which would be defined and connected in a more complex version of this workflow) to perform actions or gather information relevant to the customer's request.

Prerequisites/Requirements

n8n Instance: A running n8n instance to import and execute the workflow.
OpenAI API Key: An API key for OpenAI to use the "OpenAI Chat Model" node. This will need to be configured as an n8n credential.
LangChain Integration: The n8n LangChain nodes (@n8n/n8n-nodes-langchain) must be installed and available in your n8n instance.

Setup/Usage

Import the Workflow: Download the provided JSON and import it into your n8n instance.
Configure Credentials:
- Set up an OpenAI API credential within n8n.
- Ensure the "OpenAI Chat Model" node is configured to use this credential.
Deploy the Workflow: Activate the workflow to start listening for incoming chat messages.
Initiate Chat: Send a chat message to the configured "Chat Trigger" to test the workflow. The output of the "AI Agent" nodes will show the agent's thought process and generated responses.

Note: This workflow provides the foundational structure for a multi-agent system. To make it fully functional for specific customer support scenarios, you would typically:

Add more "tools" (e.g., CRM integration, knowledge base lookup, external API calls) to the AI agents.
Define specific prompts and instructions for the AI agents to guide their behavior.
Connect the final output of the AI agents to a messaging platform (e.g., Slack, email) to send responses back to the customer.

Automate Dutch Public Procurement Data Collection with TenderNed

TenderNed Public Procurement What This Workflow Does This workflow automates the collection of public procurement data from TenderNed (the official Dutch tender platform). It: Fetches the latest tender publications from the TenderNed API Retrieves detailed information in both XML and JSON formats for each tender Parses and extracts key information like organization names, titles, descriptions, and reference numbers Filters results based on your custom criteria Stores the data in a database for easy querying and analysis Setup Instructions This template comes with sticky notes providing step-by-step instructions in Dutch and various query options you can customize. Prerequisites TenderNed API Access - Register at TenderNed for API credentials Configuration Steps Set up TenderNed credentials: Add HTTP Basic Auth credentials with your TenderNed API username and password Apply these credentials to the three HTTP Request nodes: "Tenderned Publicaties" "Haal XML Details" "Haal JSON Details" Customize filters: Modify the "Filter op ..." node to match your specific requirements Examples: specific organizations, contract values, regions, etc. How It Works Step 1: Trigger The workflow can be triggered either manually for testing or automatically on a daily schedule. Step 2: Fetch Publications Makes an API call to TenderNed to retrieve a list of recent publications (up to 100 per request). Step 3: Process & Split Extracts the tender array from the response and splits it into individual items for processing. Step 4: Fetch Details For each tender, the workflow makes two parallel API calls: XML endpoint - Retrieves the complete tender documentation in XML format JSON endpoint - Fetches metadata including reference numbers and keywords Step 5: Parse & Merge Parses the XML data and merges it with the JSON metadata and batch information into a single data structure. Step 6: Extract Fields Maps the raw API data to clean, structured fields including: Publication ID and date Organization name Tender title and description Reference numbers (kenmerk, TED number) Step 7: Filter Applies your custom filter criteria to focus on relevant tenders only. Step 8: Store Inserts the processed data into your database for storage and future analysis. Customization Tips Modify API Parameters In the "Tenderned Publicaties" node, you can adjust: offset: Starting position for pagination size: Number of results per request (max 100) Add query parameters for date ranges, status filters, etc. Add More Fields Extend the "Splits Alle Velden" node to extract additional fields from the XML/JSON data, such as: Contract value estimates Deadline dates CPV codes (procurement classification) Contact information Integrate Notifications Add a Slack, Email, or Discord node after the filter to get notified about new matching tenders. Incremental Updates Modify the workflow to only fetch new tenders by: Storing the last execution timestamp Adding date filters to the API query Only processing publications newer than the last run Troubleshooting No data returned? Verify your TenderNed API credentials are correct Check that you have setup youre filter proper Need help setting this up or interested in a complete tender analysis solution?

Key settings: pricebook2Id (hardcoded in script): e.g., 01sxxxxxxxxxxxxxxx Source lines: $('Message a model').first().json.message.content.products Output: { soql, codes } --- 8) Query PricebookEntries (Salesforce) Purpose: Fetch PricebookEntry.Id for each Product2.ProductCode. Key settings: Resource: search Query: ={{ $json.soql }} Creds: salesforceOAuth2Api Output: Items with Id, Product2.ProductCode (used for mapping). --- 9) Code in JavaScript (Build OLI payloads) Purpose: Join lines with PBE results and Opportunity Id ➜ build OpportunityLineItem payloads. Inputs: OpportunityId: ={{ $('Create an opportunity').first().json.id }} Lines: ={{ $('Message a model').first().json.message.content.products }} PBE rows: from previous node items Output: { body: { allOrNone:false, records:[{ OpportunityLineItem... }] } } Notes: Converts discount_total ➜ per-unit if needed (currently commented for standard pricing). Throws on missing PBE mapping or empty lines. --- 10) Create Opportunity Line Items (HTTP Request) Purpose: Bulk create OLIs via Salesforce Composite API.

If AI returns non-JSON, keep “Return only a JSON array” as the last line of the prompt and keep jsonOutput enabled. Consider adding validation on parsing.warnings to gate Salesforce writes. For discounts/taxes in OLI: Standard OLI fields don’t support per-line discount amounts directly; model them in UnitPrice or custom fields. Replace the Composite API URL with your org’s domain or use the Salesforce node’s Bulk Upsert for simplicity.
