This workflow allows you to recognize a folder with receipts or invoices (make sure your files are in .pdf, .png, or .jpg format). The workflow can be triggered via the "Test workflow" button, and it also monitors the folder for new files, automatically recognizing them.

1. n8n import glitch

After import, the trigger node "When clicking 'Test workflow'" might be disconnected. You need to connect it via 2 arrows to "Google Sheets1" and "Google Drive" nodes. So, the workflow has 2 triggers - via button, and via Google Sheets "new file" event - both of these triggers should be connected to 2 nodes. Here is how it should look like: https://ocr.oakpdf.com/n8n_fix.png

2. Set up RapidAPI HTTP auth key

Create new "HTTP header" n8n credential and paste your RapidAPI key from https://rapidapi.com/restyler/api/receipt-and-invoice-ocr-api into it. https://ocr.oakpdf.com/n8n_api_key.png

Make sure "HTTP Request" node uses this credential.

3. Set up your Google Auth

You need a Google connection to work with your Google Sheets and Google Drive accounts: https://docs.n8n.io/integrations/builtin/credentials/google/oauth-generic/#finish-your-n8n-credential

4. Set up Google Sheets

Google Drive to Google Sheets Invoice/Receipt Recognition

This n8n workflow automates the process of extracting information from invoices and receipts uploaded to Google Drive and then adding that data to a Google Sheet. It's designed to streamline expense tracking and data entry by leveraging a third-party API for document recognition.

What it does

  1. Monitors Google Drive: It listens for new files (invoices/receipts) uploaded to a specified folder in Google Drive.
  2. Downloads File: When a new file is detected, it downloads the file from Google Drive.
  3. Sends to Recognition API: The downloaded file is then sent to an external API (likely a document recognition service like Mindee, although not explicitly named in the JSON, the HTTP Request node is configured for an external service) for data extraction.
  4. Processes API Response: It takes the data returned by the recognition API and transforms it into a structured format.
  5. Appends to Google Sheet: Finally, the extracted invoice/receipt data is appended as a new row to a designated Google Sheet.

Prerequisites/Requirements

  • n8n Account/Instance: A running n8n instance.
  • Google Drive Account: A Google Drive account with a specific folder for uploading invoices/receipts.
  • Google Sheets Account: A Google Sheets account with a target spreadsheet for storing the extracted data.
  • Google OAuth2 Credentials: Configured Google OAuth2 credentials in n8n to allow access to Google Drive and Google Sheets.
  • External Document Recognition API: Access to a document recognition API (e.g., Mindee, Google Document AI, etc.) that can process image/PDF files and extract structured data. This will require an API key and an endpoint URL.

Setup/Usage

  1. Import the Workflow: Import the provided JSON workflow into your n8n instance.
  2. Configure Google Credentials:
    • Set up your Google OAuth2 credentials in n8n.
    • Update the "Google Drive Trigger" node (ID: 531) to use your Google Drive credential and specify the folder ID you want to monitor for new files.
    • Update the "Google Drive" node (ID: 58) to use your Google Drive credential.
    • Update the "Google Sheets" node (ID: 18) to use your Google Sheets credential and specify the Spreadsheet ID and Sheet Name where the data should be appended.
  3. Configure HTTP Request Node:
    • Update the "HTTP Request" node (ID: 19) with the endpoint URL and any necessary authentication (e.g., API key in headers) for your chosen document recognition API.
    • Ensure the request body is correctly configured to send the file data to the API.
  4. Configure Code Node:
    • The "Code" node (ID: 834) is responsible for parsing the response from the document recognition API and formatting it for Google Sheets. You will likely need to adjust the JavaScript code within this node to match the specific JSON structure returned by your chosen API.
  5. Activate the Workflow: Once all credentials and configurations are set, activate the workflow. It will start monitoring your Google Drive folder for new files.

To test the workflow manually: You can use the "When clicking ‘Execute workflow’" (Manual Trigger, ID: 838) node to simulate a trigger and step through the workflow to ensure everything is configured correctly. You will need to manually provide dummy data for the Google Drive file in the manual trigger for a full test.

Auto-reply & create Linear tickets from Gmail with GPT-5, gotoHuman & human review

This workflow automatically classifies every new email from your linked mailbox, drafts a personalized reply, and creates Linear tickets for bugs or feature requests. It uses a human-in-the-loop with gotoHuman and continuously improves itself by learning from approved examples. How it works The workflow triggers on every new email from your linked mailbox. Self-learning Email Classifier: an AI model categorizes the email into defined categories (e.g., Bug Report, Feature Request, Sales Opportunity, etc.). It fetches previously approved classification examples from gotoHuman to refine decisions. Self-learning Email Writer: the AI drafts a reply to the email. It learns over time by using previously approved replies from gotoHuman, with per-classification context to tailor tone and style (e.g., different style for sales vs. bug reports). Human Review in gotoHuman: review the classification and the drafted reply. Drafts can be edited or retried. Approved values are used to train the self-learning agents. Send approved Reply: the approved response is sent as a reply to the email thread. Create ticket: if the classification is Bug or Feature Request, a ticket is created by another AI agent in Linear. Human Review in gotoHuman: How to set up Most importantly, install the gotoHuman node before importing this template! (Just add the node to a blank canvas before importing) Set up credentials for gotoHuman, OpenAI, your email provider (e.g. Gmail), and Linear. In gotoHuman, select and create the pre-built review template "Support email agent" or import the ID: 6fzuCJlFYJtlu9mGYcVT. Select this template in the gotoHuman node. In the "gotoHuman: Fetch approved examples" http nodes you need to add your formId. It is the ID of the review template that you just created/imported in gotoHuman. Requirements gotoHuman (human supervision, memory for self-learning) OpenAI (classification, drafting) Gmail or your preferred email provider (for email trigger+replies) Linear (ticketing) How to customize Expand or refine the categories used by the classifier. Update the prompt to reflect your own taxonomy. Filter fetched training data from gotoHuman by reviewer so the writer adapts to their personalized tone and preferences. Add more context to the AI email writer (calendar events, FAQs, product docs) to improve reply quality.
