📄 Google Script Workflow: Upload File from URL to Google Drive (via n8n)
📄 Google Script Workflow: Upload File from URL to Google Drive (via n8n) 🔧 Purpose: This lightweight Google Apps Script acts as a server endpoint that receives a file URL (from n8n), downloads the file, uploads it to your specified Google Drive folder, and responds with the file’s metadata (like Drive file ID and URL). This is useful for large video/audio files that n8n cannot handle directly via HTTP Download nodes. 🚀 Setup Steps: 1. Create a New Script Project Go to https://script.google.com Click “New Project” Rename the project to something like: DriveUploader 2. Paste the Script Code Replace the default Code.gs content with the following (your custom script): function doPost(e) { const SECRET_KEY = 'your-strong-secret-here'; // Set your secret key here try { const data = JSON.parse(e.postData.contents); // 🔒 Check for correct secret key if (!data.secret || data.secret !== SECRET_KEY) { return ContentService.createTextOutput("Unauthorized") .setMimeType(ContentService.MimeType.TEXT); } const videoUrl = data.videoUrl; const folderId = 'YOUR_FOLDER_ID_HERE'; // Replace with your target folder ID const folder = DriveApp.getFolderById(folderId); const response = UrlFetchApp.fetch(videoUrl); const blob = response.getBlob(); const file = folder.createFile(blob); file.setName('uploaded_video.mp4'); // You can customize the name return ContentService.createTextOutput(file.getUrl()) .setMimeType(ContentService.MimeType.TEXT); } catch (err) { return ContentService.createTextOutput("Error: " + err.message) .setMimeType(ContentService.MimeType.TEXT); } } 3. Generate & Set Up Secret Key To allow authorized post requests to your script only, we need to generate a secret key from aany reliable key generator. You can head over to acte, click generate and copy the "Encryption key 256". Paste it in the 'your-strong-secret-here' placeholder in your script then click save const SECRET_KEY = 'your-strong-secret-here'; // Set your secret key here; 4. Replace Folder ID in Code Open the target Drive folder in your browser The folder ID is the part of the URL after /folders/ Example: https://drive.google.com/drive/u/0/folders/1Xabc12345678defGHIJklmn Paste that ID in the script: var folderId = "1Xabc12345678defGHIJklmn"; 5. Set Up Deployment as Web App Click “Deploy” > “Manage Deployments” > “New Deployment” Under Select type, choose Web app Description: Upload from URL to Drive Execute as: Me Who has access: Anyone Click Deploy Authorize the script when prompted Copy the Web App URL 📤 How to Use in n8n 1. HTTP Request Node Method: POST URL: (your web app URL) Secret Key: (Secret Key set in script) Body Content Type: JSON Paste code: { "videoUrl": "https://example.com/path/to/your.mp4", "secret": "your-strong-secret-here" } videoUrl: The file download URL secret: The generated and set up secret key 2. Rename Node A simple drive update node to rename the file using the file drive url returned from the script. An n8n automation workflow template by Joseph.
