n8n and Apify Tutorial: How to Automate Web Scraping Workflows

n8n + Apify Tutorial

How to Use n8n with Apify for Web Scraping and Automation

Learn how to connect n8n and Apify to run Actors, scrape websites, collect structured data, and send results to apps like Google Sheets, Telegram, and CRMs.

If you want to automate web scraping and data extraction, n8n + Apify is a powerful combination. Apify handles the scraping using Actors, while n8n lets you route the output into your own workflow.

What you can build: website scrapers, lead collectors, competitor monitoring, Google Maps data extraction, content pipelines, and alert systems.

What You’ll Learn

  • What Apify does
  • How to connect Apify to n8n
  • How to run an Actor from n8n
  • How to fetch scraped results
  • How to build a simple real workflow
  • How to use HTTP Request instead of a dedicated node

What Is Apify?

Apify is a platform for running automation and web scraping tools called Actors. These Actors can extract website data, browse pages, collect structured results, and save outputs into datasets or key-value stores.

In simple terms, Apify does the scraping work, and n8n handles the automation around it.

๐Ÿ’ก Simple explanation: Apify gets the data. n8n moves the data where you need it.

Why Use n8n with Apify?

This combo is useful because you can let Apify scrape websites and let n8n handle the business logic afterward.

  • Run scrapers on demand
  • Store results in Google Sheets or databases
  • Send Telegram or email alerts
  • Trigger AI analysis of scraped content
  • Build no-code or low-code data pipelines

How n8n Connects to Apify

There are two main ways to connect n8n and Apify:

  1. Use the Apify integration/node
  2. Use the n8n HTTP Request node with the Apify API

Apify’s official n8n integration supports actions and triggers, including running Actors and reacting to Actor or task events. If you prefer raw API control, you can also use n8n’s HTTP Request node.

Step 1: Create Your Apify Account

First, create an Apify account and choose an Actor you want to run. You can use Actors from the Apify Store or your own custom Actor.

For authentication, Apify documentation says you can connect using OAuth or an Apify API token.

Step 2: Connect Apify to n8n

In n8n, add the Apify node if available in your environment, then create the credential using your Apify login or token.

Basic flow:

Trigger → Apify → Google Sheets / Telegram / Database

If you are not using the Apify node, you can connect through HTTP Request instead.

Step 3: Run an Apify Actor from n8n

The standard Apify API pattern is:

  1. Send a POST request to run the Actor
  2. Get the run response
  3. Read the defaultDatasetId
  4. Fetch the dataset items

Example Actor run endpoint:

POST https://api.apify.com/v2/acts/YOUR-ACTOR-ID/runs?token=YOUR_API_TOKEN

Sample JSON input:

{
  "startUrls": [
    { "url": "https://example.com" }
  ],
  "maxRequestsPerCrawl": 20
}
Tip: The POST payload becomes the Actor input, usually as application/json.

Step 4: Get the Scraped Results

After the Actor starts, the response includes information about the run. Apify’s API documentation explains that you typically monitor the run and then fetch results from the dataset using the defaultDatasetId.

Dataset items example:

GET https://api.apify.com/v2/datasets/YOUR_DATASET_ID/items?token=YOUR_API_TOKEN

These items can then be sent to Google Sheets, Airtable, Telegram, Supabase, or any app connected to n8n.

n8n Workflow Example

Here is a simple workflow idea:

Manual Trigger
   ↓
HTTP Request (Run Apify Actor)
   ↓
Wait
   ↓
HTTP Request (Get Dataset Items)
   ↓
Google Sheets
   ↓
Telegram

This workflow runs an Apify scraper, waits for it to finish, fetches the scraped items, stores them in Google Sheets, and sends a Telegram notification.

Example Use Cases

Google Maps lead scraping
E-commerce product monitoring
News and article collection
AI content research pipelines

Using HTTP Request Instead of a Dedicated Apify Node

n8n’s HTTP Request node can call any REST API, so it works well with Apify if you want more direct control.

Typical HTTP Request setup:

  • Method: POST
  • URL: Apify Actor run endpoint
  • Headers: Content-Type: application/json
  • Body: Your Actor input JSON

This is a good option if you want a custom workflow or if your installed n8n environment does not include the Apify node.

Common Problems and Fixes

1. Invalid API token
Double-check your Apify API token or credential setup.

2. Actor runs but no data appears
Make sure the Actor actually writes output into the dataset.

3. Dataset fetch returns empty
The run may not be finished yet. Add a Wait node or poll the run status.

4. HTTP Request errors
Verify method, URL, headers, and JSON body.

5. Wrong Actor input
Every Actor has its own input schema, so follow the specific Actor’s documentation.

Best Practices

  • Start with one Actor and one destination app
  • Test the Actor in Apify first before wiring it into n8n
  • Log raw results before transforming them
  • Use Wait or polling when the scraper takes time
  • Store API tokens securely in credentials

FAQ

Can n8n connect to Apify directly?
Yes. Apify provides an n8n integration for actions and triggers, and you can also use HTTP Request for raw API calls.

Do I need coding to use Apify with n8n?
Not much. You mainly need to understand Actor inputs, API tokens, and JSON bodies.

What is the easiest starter workflow?
Run an Actor, wait for completion, fetch dataset items, and send them to Google Sheets.

How to Create an AI Agent in n8n Using AI Agent Node and OpenAI

n8n + OpenAI Tutorial

How to Create an AI Agent in n8n Using AI Agent Node and OpenAI

Learn how to build a working AI agent in n8n using the AI Agent node, OpenAI Chat Model, tools, memory, and chat trigger.

If you want to build an AI agent inside n8n, the easiest modern setup is to use the AI Agent node together with the OpenAI Chat Model node. This lets your agent understand user requests, choose tools, and return useful answers automatically.

Important: In current n8n versions, the AI Agent now works as a Tools Agent. Also, you must connect at least one tool to the AI Agent node for it to work properly.

What You’ll Learn

  • What the AI Agent node does in n8n
  • How to connect OpenAI to n8n
  • How to add Chat Trigger, Memory, and Tools
  • How to test your first AI agent
  • Common mistakes and how to fix them

What Is the AI Agent Node in n8n?

The AI Agent node in n8n is used to create an autonomous assistant that can receive input, reason about the task, and use connected tools to perform actions or retrieve information. Instead of giving only a simple text response, an agent can decide which tool to use depending on the user’s request.

This is what makes it different from a normal prompt-based AI flow. An AI agent can do more than just answer questions. It can also interact with APIs, run tools, search knowledge, and handle more advanced logic.

๐Ÿ’ก Simple explanation: a normal AI node answers; an AI agent can also decide and act.

What You Need Before Starting

  • A working n8n instance
  • An OpenAI account and API key
  • Basic understanding of nodes and workflow connections

n8n supports OpenAI authentication using an API key. After you add the credential, you can use it in the OpenAI Chat Model node.

Basic Workflow Structure

Your first AI agent workflow in n8n will usually look like this:

Chat Trigger → AI Agent → OpenAI Chat Model
                    ↘ Memory
                    ↘ Tool(s)

This structure allows the user to send a message, the AI Agent to process it, OpenAI to generate reasoning, memory to keep context, and tools to perform actions.

Step 1: Add the Chat Trigger Node

Start by adding a Chat Trigger node. This lets you test your agent using n8n’s chat interface.

  1. Create a new workflow
  2. Add Chat Trigger
  3. Leave the default settings for now

If you want ongoing multi-message conversations, n8n recommends connecting the same memory sub-node to both the Chat Trigger and the AI Agent. This helps maintain a single source of truth for the conversation.

Step 2: Add the AI Agent Node

Next, add the AI Agent node and connect it to the Chat Trigger.

  1. Add the AI Agent node
  2. Connect Chat Trigger → AI Agent
  3. Set your system prompt or instructions inside the agent
Note: Older n8n versions had multiple agent types. In current documentation, this was removed, and AI Agent now works as a Tools Agent.

Step 3: Add the OpenAI Chat Model Node

The AI Agent needs a model to think and respond. Add the OpenAI Chat Model node and connect it to the AI Agent’s model input.

  1. Add OpenAI Chat Model
  2. Create or select your OpenAI credential
  3. Choose the model you want to use
  4. Connect it to the AI Agent model connector

In the OpenAI Chat Model node, you can optionally enable Use Responses API. When enabled, it uses OpenAI’s Responses API instead of Chat Completions. n8n also notes that OpenAI built-in tools are available only when the OpenAI Chat Model is used together with the AI Agent node.

Step 4: Add at Least One Tool

This is the step many beginners miss. The current AI Agent documentation says you must connect at least one tool sub-node to the AI Agent.

Examples of tools you can connect include:

  • HTTP Request tool
  • Calculator tool
  • Code tool
  • Knowledge/search tool
  • Sub-workflow tool
๐Ÿ’ก For a simple test, add an easy tool first so your agent can actually act on something.

Step 5: Add Memory for Conversations

If you want your AI agent to remember previous messages, attach a memory sub-node. This is useful for chatbots, customer support, and assistants that need conversation context.

For chat sessions, n8n recommends connecting the same memory node to both the Chat Trigger and the AI Agent.

Step 6: Add a System Prompt

A good system prompt tells the agent what role it should play and how it should behave.

Example system prompt:

You are a helpful AI assistant for customer support.
Answer clearly and briefly.
Use connected tools when needed.
If information is missing, ask a short follow-up question.

You can customize this for sales, support, HR, booking, lead qualification, or internal knowledge assistants.

Step 7: Test the AI Agent

Once all nodes are connected, execute the workflow and test it through the chat window.

Try sample prompts like:

  • “Summarize this request”
  • “Use the tool to fetch data”
  • “Help me answer a customer inquiry”

If everything is connected properly, the AI Agent will receive the message, use the OpenAI Chat Model for reasoning, and call the connected tool when necessary.

Simple Example Use Case

Here is a beginner-friendly example:

Chat Trigger
   ↓
AI Agent
   ├── OpenAI Chat Model
   ├── Simple Memory
   └── HTTP Request Tool

In this setup, the user asks a question, the agent decides whether it needs external information, and the HTTP Request tool can fetch that data from an API.

Common Problems and Fixes

1. Agent does not work
Check if you connected at least one tool to the AI Agent.

2. OpenAI model not responding
Verify your OpenAI API key and selected credential.

3. Memory is not working
Make sure the memory node is connected correctly, especially if using Chat Trigger sessions.

4. Multi-item expressions behave oddly
n8n notes that sub-nodes can resolve expressions differently from standard nodes.

5. API quota or bad request errors
Check your OpenAI usage, request parameters, and model configuration.

Best Practices

  • Start with one simple tool before building advanced agents
  • Write a clear system prompt
  • Use memory only when you actually need conversation context
  • Test the OpenAI credential separately if needed
  • Keep your first workflow small and easy to debug

Why This Setup Is Good

This approach is good because it is modular. You can start with a very simple AI agent, then later add more tools such as HTTP requests, Google Sheets, Telegram, CRM actions, or database queries.

It is also flexible enough to grow into customer support bots, internal assistants, data lookup bots, and AI-powered automation systems.

FAQ

Can I build an AI chatbot with n8n and OpenAI?
Yes. The usual starter setup is Chat Trigger, AI Agent, OpenAI Chat Model, memory, and at least one tool.

Do I need a tool connected to AI Agent?
Yes. Current n8n documentation says the AI Agent requires at least one connected tool sub-node.

Can the OpenAI Chat Model use the Responses API?
Yes. The OpenAI Chat Model node has a toggle for using the Responses API.

Does memory persist forever?
n8n notes that memory does not persist between sessions unless your setup is designed to handle session continuity appropriately.

n8n + Weather API

How to Use n8n with a Weather API for Alerts and Automation

Build smart weather-based workflows for alerts, logging, dashboards, and IoT using n8n and a Weather API.

In this tutorial, you will learn:
  • How to connect n8n to a Weather API
  • How to read temperature, humidity, and rain data
  • How to trigger alerts using IF conditions
  • How to send notifications to Telegram, Gmail, or Google Sheets
  • How to expand the flow for smart home or IoT projects

Why Use n8n with a Weather API?

n8n is a powerful automation platform that helps you connect apps, APIs, and logic without building a full backend from scratch. A Weather API gives you real-time data such as temperature, humidity, wind speed, and weather conditions.

When you combine both, you can build workflows like:

  • Send Telegram alerts when rain starts
  • Email yourself when temperature gets too high
  • Log weather data into Google Sheets every hour
  • Trigger IoT webhooks for fans, pumps, or warning systems
  • Create weather dashboards for home, office, or city monitoring

What You Need

  • An n8n instance
  • A Weather API key
  • A city or location to monitor
  • An output app like Telegram, Gmail, Google Sheets, or Webhook

For beginners, OpenWeather is one of the easiest APIs to use.

Basic Workflow Structure

[Schedule Trigger]
        ↓
[HTTP Request]
        ↓
[IF Node]
        ↓
[Telegram / Gmail / Google Sheets / Webhook]

This flow checks the weather on a schedule, evaluates the result, and performs an action when a condition is met.

Step 1: Add a Schedule Trigger

In n8n, add a Schedule Trigger node. This decides how often the workflow checks the weather.

Suggested schedule examples:
  • Every 30 minutes
  • Every 1 hour
  • Every morning at 6:00 AM

For rain or storm alerts, checking every 15 to 30 minutes is usually enough.

Step 2: Add an HTTP Request Node

Next, add an HTTP Request node to call the Weather API.

https://api.openweathermap.org/data/2.5/weather?q=Manila,PH&appid=YOUR_API_KEY&units=metric

Replace YOUR_API_KEY with your actual API key. This request returns live weather data for Manila in Celsius.

Recommended settings:
  • Method: GET
  • Response Format: JSON

Step 3: Understand the Response

A typical Weather API response looks like this:

{
  "weather": [
    {
      "main": "Rain",
      "description": "light rain"
    }
  ],
  "main": {
    "temp": 29.5,
    "humidity": 84
  },
  "wind": {
    "speed": 3.6
  },
  "name": "Manila"
}

The most useful fields are:

  • weather[0].main = general weather condition
  • weather[0].description = detailed condition
  • main.temp = temperature
  • main.humidity = humidity percentage
  • wind.speed = wind speed
  • name = city name

Step 4: Add an IF Node for Conditions

Now add an IF node to create your alert logic.

Example 1: Rain Alert

{{$json["weather"][0]["main"]}} = Rain

Example 2: High Temperature Alert

{{$json["main"]["temp"]}} > 35

Example 3: High Humidity Alert

{{$json["main"]["humidity"]}} > 80

You can use a single IF node or add multiple branches depending on your needs.

Step 5: Send the Alert

Connect the true path of the IF node to your output app.

  • Telegram for instant mobile alerts
  • Gmail for email notifications
  • Twilio for SMS alerts
  • Google Sheets for weather logging
  • Webhook for IoT triggers

Example Telegram message:

Weather Alert
City: {{$json["name"]}}
Condition: {{$json["weather"][0]["main"]}}
Details: {{$json["weather"][0]["description"]}}
Temperature: {{$json["main"]["temp"]}}°C
Humidity: {{$json["main"]["humidity"]}}%

Optional: Clean the Data with a Set Node

To make your workflow easier to manage, add a Set node before the IF node and keep only the fields you need.

{
  "city": "{{$json['name']}}",
  "weather": "{{$json['weather'][0]['main']}}",
  "description": "{{$json['weather'][0]['description']}}",
  "temp": "{{$json['main']['temp']}}",
  "humidity": "{{$json['main']['humidity']}}"
}

This makes the next nodes cleaner and easier to read.

Practical Use Cases

1. Rain Notification System

Send a message to your phone or group chat whenever rain is detected in your city.

2. Smart Home Automation

Trigger a webhook to turn on a fan, close windows, or activate a pump based on weather conditions.

3. School or Office Safety Alerts

Notify staff when severe heat, rain, or wind conditions are detected.

4. Weather Logging Dashboard

Save weather data every hour to Google Sheets or Supabase for reports and charts.

5. IoT and ESP32 Integration

Use n8n as the automation layer between the Weather API and your hardware system.

Tips for Better Workflows

  • Use metric units for Celsius values
  • Add error handling in case the API fails
  • Store your API key securely in n8n credentials or environment variables
  • Avoid duplicate alerts by adding cooldown logic
  • Log alerts so you can review what happened later

Example Advanced Flow

[Schedule Trigger]
        ↓
[HTTP Request: Weather API]
        ↓
[Set Node]
        ↓
[IF: Rain?]
   ├── Yes → [Telegram Alert]
   └── No  → [Google Sheets Log]

Final Thoughts

If you are building automations, dashboards, or smart alert systems, n8n plus a Weather API is a very practical combination. It is simple to set up, flexible to expand, and useful for both beginners and advanced users.

You can start with a basic rain alert, then expand into Google Sheets logging, Telegram notifications, Supabase storage, or even IoT automation for devices and sensors.

Conclusion

Using n8n with a Weather API is one of the easiest ways to build real-time automation based on environmental data. With just a few nodes, you can monitor weather conditions, trigger alerts, log history, and connect the workflow to other apps or devices.
