Hey folks,

I’m trying to fetch YouTube video comments using the YouTube Data API within the n8n Code node, handling pagination to retrieve all comments. The inputs I’m passing are:

• YouTube Video ID

• Google API Key.

The output I am getting is “Comments - No Array”. Can you please help where I am going wrong

Code - // Use URLSearchParams to construct query strings natively

// Define the base URL for the YouTube Data API  
const BASE\_URL = “[https://www.googleapis.com/youtube/v3/commentThreads](https://www.googleapis.com/youtube/v3/commentThreads)”;

// Get the first input item  
const item = $input.first();

// Extract the videoId and apiKey from the input JSON  
const videoId = item.json.VIDEO\_ID;  
const apiKey = item.json.GOOGLE\_API\_KEY;

const comments = ;  
let nextPageToken = undefined;

do {  
// Construct URL parameters  
const params = {  
part: “snippet”,  
videoId: videoId,  
key: apiKey,  
maxResults: 100 // Maximum number of results per page  
};

```
if (nextPageToken) {
    params.pageToken = nextPageToken;
}

// Build the full URL
const queryString = Object.entries(params).map(([key, value]) => {
    return `${encodeURIComponent(key)}=${encodeURIComponent(value)}`;
}).join('&');
const url = `${BASE_URL}?${queryString}`;

// Set up the options for the HTTP request helper
const options = {
    method: "GET",
    uri: url,
    json: true
};

try {
    // Use n8n's built-in HTTP request helper
    const data = await this.helpers.httpRequest(options);

    // Process each comment in the response
    data.items.forEach(item => {
        comments.push(item.snippet.topLevelComment.snippet.textOriginal);
    });

    // Update the nextPageToken
    nextPageToken = data.nextPageToken;

    // Rate limiting: pause between requests to avoid hitting rate limits
    await new Promise(resolve => setTimeout(resolve, 100)); // 100ms delay; adjust as needed
} catch (error) {
    // Handle errors gracefully
    console.error('Error fetching comments:', error.message);
    break;
}

```

} while (nextPageToken);

// Return the collected comments as an item output for n8n  
return [{ json: { comments } }];

Oh, that looks complex. Maybe an easier approach is to use HTTP Request node.

Here’s an example with pagination enabled:
