> How the n8n ProLevelMax review workflow works: the /v1/run request, the JSON body, the key error, the AI themes prompt and the Google Sheets row.

Quick answer

The n8n ProLevelMax review workflow runs every Friday at 8:00. One **HTTP Request** node asks ProLevelMax for a company's newest Trustpilot reviews, a **Code** node keeps each review's rating, title, text and date, **OpenAI** writes the top complaints, top praise and one talking point as [JSON](https://learn.ynteractive.com/content/glossary/json), a second **Code** node turns that into a row, and **Google Sheets** appends it. The free [n8n ProLevelMax review digest lesson](https://learn.ynteractive.com/content/n8n-prolevelmax-trustpilot-review-themes-google-sheets) builds it on real screens from 20 October 2026.

ProLevelMax · n8n · FAQ · Google Sheets · Reviews

What the lesson actually ran: the ProLevelMax call used a placeholder key, so it shows ProLevelMax's own **invalid key format** answer. The steps after it ran on pinned SAMPLE reviews (made up), and the [OpenAI](https://learn.ynteractive.com/content/glossary/openai) step ran for real on those samples. No key was created, **Collect** was never run and no row was written to a real sheet. The example, Marcus Reed of Fieldstone [CRM](https://learn.ynteractive.com/content/glossary/crm) Consulting, is made up.

## What does each node do?

| Node | Name on the canvas | What it does |
| --- | --- | --- |
| Schedule Trigger | **Every Friday at 8am** | Runs it every Friday at 8:00 |
| HTTP Request | **Get new reviews (ProLevelMax)** | Asks for the newest 30 Trustpilot reviews of pipedrive.com |
| Code | **Keep rating and text** | Trims each review and works out the average |
| OpenAI | **Find the themes** | Top complaints, top praise, one talking point |
| Code | **Make the sheet row** | Names each field like a sheet column |
| Google Sheets | **Add this week's row** | Append Row, Map Automatically |

## How is the ProLevelMax request set up?

In **Get new reviews (ProLevelMax)**, **Method** is **POST** and **URL** is `https://prolevelmax.com/v1/run`, the same address for every source. **Authentication** is **Generic Credential Type** with **Generic Auth Type** **Bearer Auth**, and the lesson's credential is named **ProLevelMax - add your key**. **Send Body** is on, as JSON:

```text
{"scraper": "procli_trustpilot_a", "input": {"companyUrls": ["pipedrive.com"], "maxReviewsPerCompany": 30, "sort": "recency", "languages": ["en"]}, "maxItems": 30}
```

**scraper** is the source id. **input** holds the same field names you see in the console's **Collect** form. The node's **Timeout** option is 2 minutes, because collecting reviews takes a little while (see [workflow timeout](https://learn.ynteractive.com/content/glossary/workflow-timeout)).

## Where do the field names come from?

From the ProLevelMax console. Open **Data sources**, type **trustpilot** in **Search sources**, and find **Company reviews** with the id **procli_trustpilot_a**. Click **Collect** to see its fields: **companyUrls**, **maxReviewsPerCompany**, **stars**, **languages**, **sort**, **date** and others. Then click **Close**, not **Run**.

## What did the AI step write?

On 8 sample reviews, the real OpenAI run returned price increases and features gated behind higher plans or add-ons, limited reporting and clunky exports, and slow customer support as the complaints. The praise was an easy, clean setup, the drag-and-drop pipeline and a strong mobile app. The sample row showed an average rating of 3.3. These came from made-up reviews, so they say nothing about the real product.

## Frequently asked questions

**Where do I get a ProLevelMax key?**

Sign up at prolevelmax.com, open **API keys** in the console and click **+ New key**. Copy it into an n8n Bearer Auth [credential](https://learn.ynteractive.com/content/glossary/credential), in **Bearer Token**. The [API key](https://learn.ynteractive.com/content/glossary/api-key) entry covers why it stays out of the workflow itself.

**Why does the test run say invalid key format?**

The lesson used a placeholder in the credential, so ProLevelMax answered **Authorization failed**: **invalid key format**. It shows n8n reached ProLevelMax with the right URL and header. With your key, the reviews come back in **items**.

**Does clicking Run in the Collect form cost anything?**

Yes. **Run** charges your balance. You don't need it, because n8n makes the call. Open **Collect** only to read the field names.

**Why trim the reviews before the AI step?**

**Keep rating and text** keeps each review's **rating**, **title**, **text** (cut to 700 characters) and **date** for up to 30 reviews, plus the **count** and **average**. The AI gets only what it needs. The code checks a few common field names, so look at one real run's output and adjust the names if ProLevelMax's differ.

**Why does the prompt ask for JSON?**

The prompt says to use only what the reviews say, invent no numbers and reply with JSON only: **top_complaints**, **top_praise** and **talking_point**. A fixed shape means **Make the sheet row** can put each answer in its own column every week. This is a simple form of [structured output](https://learn.ynteractive.com/content/glossary/structured-output).

**What if the AI adds a code fence or extra text?**

**Make the sheet row** strips a code fence before reading the JSON. If it still can't read it, the raw answer lands in **Top complaints**, so nothing is lost.

**How should the sheet be set up?**

Row 1 needs **Week**, **Company**, **Reviews read**, **Average rating**, **Top complaints**, **Top praise** and **Talking point**. The lesson's guide page has a CSV with those headers. In **Add this week's row**, paste your sheet's URL in **Document** and set **Mapping Column Mode** to **Map Automatically**, so each field lands in the column with the same name.

**Which OpenAI credential does it use?**

The lesson's OpenAI node used the OpenAI credential that came with the n8n Cloud account. You can also connect your own OpenAI key.

**Can I read G2, Capterra or Google Maps reviews instead?**

Yes. The Data sources list includes review sites such as G2, Capterra, Google Maps and Yelp, each with its own id and fields. Swap the **scraper** id and use that source's field names from its **Collect** form.

**Can it watch more than one company?**

**companyUrls** is a list, so you can add companies. Then change the Code node to group reviews by company before the AI step, or run one workflow per company.

**Is this an official ProLevelMax course?**

No. It is Stepthrough's own lesson. For the Reddit version of ProLevelMax in n8n, see the [ProLevelMax Reddit API FAQ](https://learn.ynteractive.com/content/blog/prolevelmax-reddit-api-faq).

## Key takeaways

- One address, `https://prolevelmax.com/v1/run`, takes a source id and its input.
- Read field names in **Collect**, then close it. **Run** charges your balance.
- **invalid key format** in a test means only the key is missing.
- Ask the AI for JSON with fixed names so each answer has its own column.
- The lesson's themes came from made-up sample reviews.
