Getting Down to Business: How to Integrate Claude Sonnet 4 with n8n

Alright, enough with the hype. Let's get to the good stuff. Here’s how you actually connect Claude Sonnet 4 to n8n. It's surprisingly straightforward.

Step 1: Get Your Anthropic API Key

First things first, you need an API key from Anthropic. This is what allows n8n to talk to Claude.

Head over to the Anthropic Console.
If you don't have an account, you'll need to create one. You'll also need to add a little bit of credit to your account to use the API, but it's super cheap.
Once you're in, navigate to the "API Keys" section.
Create a new key & give it a descriptive name (like "n8n Integration").
Copy that key & save it somewhere safe. You won't be able to see it again!

Step 2: Set Up the Anthropic Node in n8n

Now, let's jump into your n8n workflow.

Open up a new or existing workflow in n8n.
Add a new node & search for "Anthropic." You'll see a few options, but the one you want is the "Anthropic Chat Model" or something similar. If you can't find it, you might need to make sure your n8n instance is up to date.
In the node's properties, you'll see a field for "Credentials." Click on it & select "Create New."
Paste your Anthropic API key into the field & save it. You'll see a nice green light once it's authenticated.

Step 3: Configure the Node

Now that you're connected, you just need to tell the node what you want it to do.

Select the Model: In the node's settings, you'll see a dropdown menu for the model. Make sure you select "Claude Sonnet 4."
Craft Your Prompt: This is where the magic happens. The "System Prompt" is where you give Claude its instructions. Be as specific as you can. Tell it what you want it to do, what kind of tone to use, & any other important details.

And that's it! You've officially connected Claude Sonnet 4 to n8n. Now, let's look at some of the awesome things you can do with it.

Putting It All to Work: E-commerce Automation Recipes

This is where things get REALLY fun. Here are a few ideas to get your creative juices flowing.

1. The "Never-Miss-a-Sale" Abandoned Cart Saver

Abandoned carts are the bane of every e-commerce store's existence. Here's how you can use Claude & n8n to win back those lost sales.

Trigger: Your e-commerce platform (like Shopify or WooCommerce) has a "Cart Abandoned" trigger.
Claude Node: Feed the customer's cart information to Claude. Your prompt could be something like: "A customer just abandoned their cart. Here are the items they had in it: [list of items]. Write a friendly & helpful email reminding them about their cart. Offer them a 10% discount to complete their purchase."
Email Node: Take the email that Claude generates & send it to the customer.

This is way more powerful than a generic "You left something in your cart" email. Claude can tailor the message to the specific products the customer was interested in, making it much more likely to convert.

2. The 24/7 AI Customer Service Rep

Customer service can be a huge time-suck, but it's also incredibly important. With Claude & n8n, you can build a customer service bot that can handle a huge range of queries, freeing up your team to focus on more complex issues.

Here's a cool way to do it: instead of building a chatbot from scratch, you can use a platform like Arsturn. Here's the thing, Arsturn helps businesses create custom AI chatbots trained on their own data. This means you can create a chatbot that knows your products inside & out. It can answer questions about shipping, returns, product specs, you name it. And because it's available 24/7, your customers can get the help they need whenever they need it. This is a great way to boost customer satisfaction & reduce the load on your support team.

3. The "Personal Shopper" Product Recommender

Personalization is the name of the game in e-commerce. Here's how you can use Claude to provide personalized product recommendations.

Trigger: A customer makes a purchase.
Claude Node: Feed the customer's purchase history to Claude. Your prompt could be: "A customer just bought [list of items]. Based on these items, what other products would you recommend? Provide a short, friendly description for each recommendation."
Email Node: A week or so after their purchase, send the customer an email with their personalized recommendations.

This is a great way to increase customer lifetime value & show your customers that you "get" them.

4. The "Always-in-Stock" Inventory Manager

Running out of a popular product is a nightmare. Here's how you can use n8n & Claude to stay on top of your inventory.

Trigger: A "Schedule" trigger that runs once a day.
HTTP Request Node: Connect to your e-commerce platform's API to get your current inventory levels.
Claude Node: Feed the inventory data to Claude. Your prompt could be: "Here are my current inventory levels: [inventory data]. Identify any products that are running low (less than 10 units in stock) & draft a purchase order to reorder them."
Email/Slack Node: Send the purchase order to your supplier or a notification to your team.

This is a simple but powerful way to avoid stockouts & keep your customers happy.

Power-Up Your Workflows with Arsturn

As you can see, the possibilities are pretty much endless. And if you want to take your store automation to the next level, you should definitely check out Arsturn. It's a no-code AI chatbot builder that lets you train a chatbot on your own data. This is perfect for e-commerce stores because you can create a chatbot that can:
