# n8n + Felo API FAQ: A Weekly Research Brief With Sources

> How the n8n Felo workflow works: the HTTP Request node, Bearer Auth key, JSON body, Invalid API Key test, pinned sample answers and the Gmail brief.

Quick answer

The n8n Felo workflow is five nodes: a **Schedule Trigger** runs every Monday at 7:00, a **Code** node holds your questions, one **HTTP Request** node sends each question to Felo's [API](https://learn.ynteractive.com/content/glossary#api) at `https://openapi.felo.ai/v2/chat`, a second **Code** node builds one email with each answer and its top 3 sources, and **Gmail** sends it. You set up a [Bearer Auth](https://learn.ynteractive.com/content/glossary#bearer-token) credential with your Felo key, and nothing else in the workflow holds the key. The free [n8n Felo research brief lesson](https://learn.ynteractive.com/content/n8n-felo-api-weekly-research-brief) walks through every node on real screens captured on 20 October 2026.

One honest note before the answers. The lesson's test call used a placeholder key on purpose, so it shows Felo's own **Invalid API Key** answer. The email step then ran on pinned sample answers marked **SAMPLE**, which are made up. So this page tells you what the setup looks like and what Felo's docs say comes back, not what a real answer looked like. The example business, Lakeshore Bookkeeping and its owner Priya Nair, is made up too.

## What does each node in the workflow do?

| Node | Name on the canvas | What it does |
| --- | --- | --- |
| [Schedule Trigger](https://learn.ynteractive.com/content/glossary#schedule-trigger) | **Every Monday at 7am** | Runs the workflow every week, Monday, 7:00 |
| Code | **This week's questions** | Returns one item per question |
| HTTP Request | **Ask Felo** | POSTs each question to Felo |
| Code | **Build the brief** | Pairs answers with questions, keeps 3 sources each |
| Gmail | **Email the brief** | Sends one HTML email to you |

Because the questions node returns one [item](https://learn.ynteractive.com/content/glossary#item) per question, **Ask Felo** runs once for each. Three questions means three calls.

## How is the HTTP Request node set up?

Open **Ask Felo**. The settings in the lesson are:

- **Method**: **POST**
- **URL**: `https://openapi.felo.ai/v2/chat`
- **Authentication**: **Generic Credential Type**, then **Generic Auth Type**: **Bearer Auth**
- **Send Body** on, as **JSON**, with this body: `{ "query": {{ JSON.stringify($json.question) }} }`

The credential in the lesson is named **Felo - add your key**. You create it, paste your key into **Bearer Token** and save. n8n then sends the key as a [bearer token](https://learn.ynteractive.com/content/glossary#bearer-token) on every call. If the [HTTP Request node](https://learn.ynteractive.com/content/glossary#http-request-node) is new to you, the glossary entry covers the basics.

## What does Felo send back?

According to Felo's Chat API docs, as the lesson reports them: a **status**, and **data** with **answer** (the text), **query_analysis.queries** (the searches it ran) and **resources**, a list of sources, each with a **link**, **title** and **snippet**. **Build the brief** reads **data.answer** and the first 3 entries in **data.resources**.

## What does the Monday email look like?

**Build the brief** returns one item with a **subject**, such as **Monday research brief, 2026-10-20**, and an **html** body. Each question becomes a heading, then the answer, then a short **Sources** list of links. The email opens with one line: check the sources before you act on anything. In **Email the brief**, **Subject** is `{{ $json.subject }}`, **Email Type** is **HTML** and **Message** is `{{ $json.html }}`.

## Frequently asked questions

**Where do I get a Felo API key?**

Sign in at openapi.felo.ai with your Felo account and open **API Keys**. Give the key a name such as **n8n** and click **Create Key**. Copy it straight into an n8n credential. The [API key](https://learn.ynteractive.com/content/glossary#api-key) entry explains why it is treated like a password.

**Where does the key go in n8n?**

Only in a Bearer Auth [credential](https://learn.ynteractive.com/content/glossary#credential), in the **Bearer Token** field. Never in the URL, the JSON body or a Code node. The downloaded workflow has no credentials in it, so you add your own after you paste it onto the canvas.

**Why does the lesson's test show Authorization failed?**

The test used a placeholder in the credential, so Felo answered **Authorization failed** and **Invalid API Key**. That is useful: it means n8n reached Felo and Felo read the header, so the URL, method and Bearer Auth setup are right. Only the key is missing. Paste your key in and run it again.

**Why use JSON.stringify in the body?**

It turns the question into a safe JSON string. A question with a quote mark in it would break a body you typed by hand. The [JSON](https://learn.ynteractive.com/content/glossary) entry shows what a valid body looks like.

**Did the lesson show a real Felo answer?**

No. No key was created and no email was sent. The answers you see in **Build the brief** are pinned sample answers marked **SAMPLE**, written in the shape Felo's docs give. Your first real run is the first time you will see Felo's own text.

**What are the pinned sample answers for?**

[Pinned data](https://learn.ynteractive.com/content/glossary/pinned-data) lets you test the nodes after **Ask Felo** without calling Felo. The canvas after the test run shows the sample answers pinned on **Ask Felo**. When your key is in place, unpin them so a test uses Felo's real answers.

**Can I change the questions or the day?**

Yes. Edit the list in **This week's questions**: one line per question. Change the day and hour in **Every Monday at 7am**. The workflow's time zone is New York, which you can change in the workflow settings (see [workflow time zone](https://learn.ynteractive.com/content/glossary#workflow-timezone)).

**How many questions can I add?**

Each question is one Felo API call, so check Felo's own API docs for usage terms before you add more questions or run it daily.

**Can I trust the answers in the email?**

Treat them as a starting point. Felo answers from live [AI search](https://learn.ynteractive.com/content/glossary#ai-search) and returns its sources, which is why the brief keeps 3 links per answer. Open the link before you act on a rule change or a price. The [Felo research mistakes guide](https://learn.ynteractive.com/content/blog/felo-research-mistakes) shows why a cited source can still be second-hand.

**How do I turn it on?**

Put your own address in **To**, click **Execute** and read the test email. Keep the workflow off until it looks right, then click **Publish** so it runs every Monday.

**Is this an official Felo course?**

No. It is Stepthrough's own lesson. Felo is a separate product from felo.ai. For how the Felo app itself works, see the [Felo AI search FAQ](https://learn.ynteractive.com/content/blog/felo-ai-search-faq).

## Key takeaways

- Five nodes: Schedule Trigger, a questions Code node, one HTTP Request to Felo, a brief-building Code node and Gmail.
- **Ask Felo** is **POST** to `https://openapi.felo.ai/v2/chat` with a Bearer Auth credential and a one-field JSON body.
- **Invalid API Key** in a test means the setup is right and only the key is missing.
- The lesson's brief ran on pinned SAMPLE answers. Your first real answer comes after you add your key.
- Keep the 3 source links in the email and open them before you act.
