How to Build Your Own Amazon Keywords Tool with n8n (For Free and No Coding)

I was helping my friend out who runs an Amazon FBA business. He was paying alot of money for Helium 10 and I suggested he can build his own tools for FREE using n8n.

Here’s the thing: those fancy keyword tools that cost hundreds per month? You don’t need them. I’ll show you how to build your own Amazon keyword research tool using n8n – completely free and without writing a single line of code.

Amazon has an autosuggest toolbar that gives you the keywords people are looking for

Why Build Your Own Amazon Keywords Tool?

Helium 10 and Jungle Scout are great tools, but they’ll eat up your profits fast. My friend spent $200 monthly on these tools when he started selling on Amazon. That’s $2,400 a year – money better spent on inventory or ads.

Your own keyword tool can:

• Pull real-time search data from Amazon
• Track keyword rankings daily
• Export data straight to your spreadsheets
• Run 24/7 without monthly fees

Best part? It takes just 15 minutes to set up.

What You’ll Need

Let’s grab these free items:

• n8n account (sign up here)
• Amazon Product API access (free for sellers)
• Google Sheets account
• 15 minutes of focus time

Setting Up n8n

1. Head to n8n.io and click “Sign Up”
2. Pick the free cloud option
3. Log in to your new dashboard

The n8n interface looks like a blank canvas with a menu on the left. Think of it as Lego blocks for data – we’ll connect these blocks to build our tool.

Creating Your First Workflow

All you need to do is download my free template to get started. You’ll get a fully functional workflow like the one below.

Setting Up Airtable

Here’s the most complicated part. You need to somehow send the keyword to the API. No worries, you can do this with airtable with no code.

I’ve created an airtable that you can simply press a BUTTON and it’ll send over the keyword. In the above example, I send christmas toys and it returns a bunch of other keywords.

Linking up Airtable to n8n

Go into your workflow and click on webhook URL. Go to test URL and copy that URL.

Now copy and paste that URL into airtable. Go to airtable, go to Trigger and Edit field. Replace the formula.

CONCATENATE('https://n8n.rumjahn.com/webhook-test/e1df17af-e8b8-4261-ba45-aba7106c65bd?',RECORD_ID())

Replace everything before the ? and paste your test URL.

Running your workflow

Go to your n8n and click on Test workflow. It will now “listen” for a trigger. Go to airtable and click on the trigger button. Boom! It should send over the keyword and you’ll get an output.

You can do alot with this tool and expand on it. You can find volume and more details about the keywords if you expand the API call inside the “Get keyword” node.
