n8n OpenRouter Tutorial: Build Multi-Model AI Automation Workflows

n8n + OpenRouter Tutorial

How to Use n8n with OpenRouter for Multi-Model AI Automation

Learn how to connect n8n to OpenRouter and use multiple AI models in one automation workflow.

If you want to build flexible AI automations, combining n8n with OpenRouter is a powerful setup. OpenRouter gives you access to many AI models through one unified API, while n8n lets you automate how those models are used.

💡 Example: user submits a question → n8n sends it to OpenRouter → AI generates a response → result is sent to Telegram, Gmail, CRM, or your website chatbot.

What You’ll Learn

• What OpenRouter is
• How to connect OpenRouter to n8n
• How to call AI models using HTTP Request
• How to use dynamic prompts from previous nodes
• How to build real AI automation workflows

What Is OpenRouter?

OpenRouter is a unified AI model gateway. Instead of integrating many separate AI providers one by one, you can call different models through one OpenRouter API.

This is useful when you want to test different models for chatbots, AI agents, blog automation, summarization, customer support, and internal tools.

Simple explanation: OpenRouter is like a router for AI models. n8n sends the request, OpenRouter sends it to the selected AI model.

Step 1: Get Your OpenRouter API Key

1. Create or log in to your OpenRouter account
2. Go to API Keys
3. Create a new API key
4. Copy and save it securely

⚠️ Security tip: never expose your OpenRouter API key in frontend code or public pages.

Step 2: Add HTTP Request Node in n8n

OpenRouter can be connected using the n8n HTTP Request node.

HTTP Request settings:

• Method: POST
• URL: https://openrouter.ai/api/v1/chat/completions
• Authentication: None or Generic Header Auth
• Send Body: JSON

Headers:

Content-Type: application/json
Authorization: Bearer YOUR_OPENROUTER_API_KEY

Step 3: Send Your First AI Request

Example JSON body:

{
  "model": "openai/gpt-4o-mini",
  "messages": [
    {
      "role": "system",
      "content": "You are a helpful AI automation assistant."
    },
    {
      "role": "user",
      "content": "Explain n8n in simple terms."
    }
  ]
}

After executing the node, OpenRouter will return an AI-generated response from the selected model.

Step 4: Use Dynamic Data from Previous Nodes

In real workflows, your prompt usually comes from a webhook, form, chat widget, Google Sheet, or database.

Example dynamic message:

{
  "model": "openai/gpt-4o-mini",
  "messages": [
    {
      "role": "system",
      "content": "You are a helpful customer support assistant."
    },
    {
      "role": "user",
      "content": "{{ $json.message }}"
    }
  ]
}

This lets n8n send user input directly to OpenRouter and use the response in the next node.

Step 5: Extract the AI Response

The AI response is usually returned inside the output JSON. In many chat completion responses, the generated text can be found in:

{{ $json.choices[0].message.content }}

You can pass this value to Telegram, Gmail, Google Sheets, WordPress, CRM, or a website chatbot.

Example n8n + OpenRouter Workflow

Webhook / Chat Trigger
   ↓
Set
   ↓
HTTP Request (OpenRouter)
   ↓
Set / Extract AI Response
   ↓
Telegram / Gmail / Google Sheets / WordPress

This workflow receives input, sends it to an AI model through OpenRouter, extracts the AI answer, and sends it to another app.

Real Use Cases

AI chatbot replies

Blog post generation

Email auto-response

AI agent workflows

Document summarization

Customer support automation

Example: AI Support Bot with OpenRouter

You can use OpenRouter as the AI brain of a support bot. A simple workflow can look like this:

Website Chat Form
   ↓
n8n Webhook
   ↓
OpenRouter AI
   ↓
Business Logic / IF Node
   ↓
Reply to User
   ↓
Log to Google Sheets

This is useful for schools, LGUs, service businesses, online stores, and internal helpdesks.

Common Errors and Fixes

1. Unauthorized error
Check your Authorization header and make sure it uses Bearer YOUR_API_KEY.

2. Model not found
Confirm the model ID from the OpenRouter models page before using it.

3. Empty response
Check your messages array and make sure user content is not blank.

4. Wrong output expression
Inspect the HTTP Request output and adjust the expression path if needed.

5. High cost or slow response
Try a smaller model for simple tasks and reserve larger models for complex reasoning.

Best Practices

• Start with a low-cost model for testing
• Use clear system prompts
• Log prompts and responses during development
• Keep API keys inside n8n credentials or secure variables
• Use IF nodes to handle errors or empty responses
• Use different models depending on task complexity

How to Create AI Images with n8n and Google Gemini

Learn how to automate AI image generation using n8n, Google Gemini, Google Sheets, and Google Drive.

If you want to create images automatically for blogs, YouTube thumbnails, social media posts, product visuals, or marketing content, combining n8n with Google Gemini is a powerful workflow.

💡 Example: Google Sheets contains image ideas → n8n reads the rows → Gemini generates images → n8n saves them to Google Drive → status updates automatically.

What You’ll Learn

• How Gemini image generation works
• How to connect Gemini API to n8n
• How to generate images from text prompts
• How to save generated images to Google Drive
• How to build a full content automation workflow

What Is Google Gemini Image Generation?

Google Gemini can generate and process images using text prompts, reference images, or a combination of both. This makes it useful for creating thumbnails, social media graphics, blog images, concept art, product visuals, and marketing assets.

Google also provides Imagen models for high-fidelity image generation. Imagen is designed to generate realistic, high-quality images from text prompts.

Simple explanation: Gemini creates the image, while n8n automates the full process around it.

Step 1: Prepare Your Google Gemini API Key

First, get your Gemini API key from Google AI Studio or your Google AI developer account.

1. Go to Google AI Studio
2. Create or select your API key
3. Copy the key
4. Store it securely in n8n credentials or environment variables

⚠️ Security tip: never expose your API key in frontend code or public blog pages.

Step 2: Create the n8n Workflow Structure

Google Sheets Trigger
   ↓
Get Row / Prompt
   ↓
HTTP Request or Gemini Node
   ↓
Convert Base64 / Download Image
   ↓
Google Drive Upload
   ↓
Update Google Sheet
   ↓
Telegram Notification

This workflow is useful if you want to generate images in bulk from a spreadsheet.

Step 3: Prepare Your Google Sheet

Create a Google Sheet with these columns:

• title – image topic or content title
• prompt – full image prompt
• status – pending / done / failed
• image_url – final uploaded image link

Example prompt:

A futuristic n8n automation dashboard with glowing nodes, dark background, cinematic lighting, high-tech UI, no text

Step 4: Generate Image Using Gemini API

In n8n, you can use either a Gemini-supported node or the HTTP Request node to call the Gemini image generation endpoint.

Typical HTTP Request setup:

• Method: POST
• Authentication: API key or Bearer token, depending on your setup
• Body type: JSON
• Prompt: use dynamic value from Google Sheets

Example dynamic prompt:

{{ $json.prompt }}

💡 Tip: For blog thumbnails, add style details like “cinematic lighting,” “dark tech background,” “3D vector style,” and “no text” for cleaner output.

Step 5: Save the Generated Image

Image generation APIs often return either a downloadable image URL or base64 image data. In n8n, your next step depends on the response type.

• If the API returns a URL, use HTTP Request to download the file.
• If the API returns base64, convert it to binary data.
• Then upload the file to Google Drive, Supabase Storage, or WordPress media.

Workflow sample:

Gemini Image Response
   ↓
Convert to Binary
   ↓
Google Drive Upload
   ↓
Get Share Link
   ↓
Update Google Sheet

Step 6: Update Google Sheet Status

n8n + PostgreSQL Tutorial

How to Use n8n with PostgreSQL for Database Automation

Learn how to connect n8n to PostgreSQL, run queries, insert and update rows, and automate database workflows with triggers and notifications.

If you want to automate database tasks, combining n8n with PostgreSQL is a strong setup. PostgreSQL stores your structured data, while n8n handles the workflow logic around it.

💡 Example: when a form is submitted, n8n can save the lead to PostgreSQL, notify your team on Telegram, and send an email automatically.

What You’ll Learn

• How to connect PostgreSQL to n8n
• How to run SELECT queries
• How to INSERT new rows
• How to UPDATE existing records
• How to DELETE rows safely
• How to use PostgreSQL Trigger in n8n

Why Use n8n with PostgreSQL?

PostgreSQL is a powerful relational database used for apps, dashboards, internal systems, and business workflows. n8n makes it easier to automate what happens before and after your database actions.

• Save leads or orders automatically
• Read customer or system data on demand
• Update statuses after payments or approvals
• Trigger automations when rows change
• Connect database events to email, Telegram, APIs, and CRMs

Step 1: Prepare Your PostgreSQL Database

Before connecting n8n, make sure your PostgreSQL server is ready and you have these connection details:

• Host
• Port
• Database name
• Username
• Password

It is best to create a dedicated database user for n8n instead of using your main admin account.

⚠️ Security tip: only give the n8n database user the permissions it needs.

Step 2: Add Postgres Credentials in n8n

n8n has official Postgres credentials support. Create a new Postgres credential and enter your database connection settings.

1. Open Credentials in n8n
2. Create a new Postgres credential
3. Enter host, port, database, username, and password
4. Save and test the connection

After that, you can use the Postgres node inside your workflows.

Step 3: Read Data with SELECT

To read data from PostgreSQL, use SELECT.

SELECT id, full_name, email
FROM customers
ORDER BY id DESC;

This is useful for reading customers, orders, attendance logs, payments, and other records.

Step 4: Insert New Rows

To save new data, use INSERT.

INSERT INTO customers (full_name, email, phone)
VALUES ('John Doe', 'john@example.com', '09171234567');

This works well for form entries, lead capture, registrations, chatbot logs, and order records.

Step 5: Update Existing Records

To change existing records, use UPDATE.

UPDATE customers
SET phone = '09998887777'
WHERE id = 1;

This is useful for updating payment status, approval state, timestamps, or workflow progress.

Step 6: Delete Rows Carefully

To remove data, use DELETE. Always include a clear WHERE condition.

DELETE FROM customers
WHERE id = 1;

Warning: if you run DELETE without a WHERE clause, you can remove all rows from the table.

Step 7: Use Dynamic Data from Previous Nodes

One of the best parts of n8n is using data from earlier nodes inside your Postgres workflow.

Example expression:

{{ $json.email }}

This lets you insert, search, or update rows using form values, webhook data, chatbot output, or API responses.

Step 8: Use Postgres Trigger for Event-Based Automation

n8n also has a Postgres Trigger node that can respond to database events. According to n8n’s docs, it supports reacting to insert, update, and delete events.

Postgres Trigger
   ↓
IF
   ↓
Telegram / Gmail / HTTP Request / Google Sheets

This is useful when you want instant automation whenever a row changes in your database.

Example n8n + PostgreSQL Workflow

Webhook
   ↓
Set
   ↓
Postgres (INSERT lead)
   ↓
Postgres (SELECT saved record)
   ↓
Telegram
   ↓
Gmail

In this workflow:

• A webhook receives incoming data
• A Set node formats the fields

• The Postgres node inserts the record
• Another Postgres step reads the row
• Telegram and Gmail notify your team

Real Use Cases

Lead capture systems

Order and invoice tracking

Attendance and RFID systems

Internal dashboards and CRMs

Best Practices

• Use a separate PostgreSQL user for n8n
• Test SELECT first before running UPDATE or DELETE
• Log important outputs during development
• Keep your SQL simple and readable
• Use UTC and ISO 8601 dates when possible

Common Errors and Fixes

1. Connection failed
Check host, port, username, password, and whether your PostgreSQL server accepts external connections.

2. Access denied
Your database user may not have the needed privileges.

3. Query returned nothing
Review your table name, filters, and incoming data.

4. Wrong data inserted
Check your n8n expressions and field mapping.

5. Array or date issues
n8n’s Postgres common issues page recommends careful parameter handling, UTC for dates, and ISO 8601 formatting to avoid timezone confusion.
