Automate LINE Message Receipts to Google Sheets
detail.loadingPreview
Streamline your business by automatically capturing transaction details from LINE messages and saving them to Google Sheets. This workflow leverages OCR to extract information from images, making data entry a thing of the past.
About This Workflow
This n8n workflow automates the process of receiving images from a LINE bot, extracting transaction details using Optical Character Recognition (OCR), and storing this structured data into a Google Sheet.
When a user sends an image receipt to your LINE bot, this workflow triggers. It first fetches the image content from LINE and then sends it to an OCR service (like SpaceOCR) to convert the image into text. The extracted transaction details, such as amount, sender, receiver, and transaction ID, are then parsed and meticulously recorded into a designated Google Sheet.
This solution is ideal for businesses that receive payment confirmations or receipts via LINE and need an efficient way to manage and track these transactions without manual data entry.
Key Features
- LINE Bot Integration: Seamlessly connects with your LINE bot to receive incoming messages.
- Image to Data Extraction: Utilizes OCR technology to extract key information from receipt images.
- Automated Google Sheets Entry: Directly logs parsed transaction data into your Google Sheet for easy management.
- Secure Credential Handling: Manages API keys and authentication securely for robust operation.
How To Use
- Set up LINE Webhook: Configure your LINE bot to send incoming messages to the n8n webhook node (
Line Chat Bot). Ensure your webhook URL is correctly registered with LINE. - Configure Image Fetching: The
Image slip URL in Linenode dynamically constructs the URL to fetch the image content from LINE using the message ID. TheGet image to Binarynode uses this URL and a configured HTTP header authentication credential to download the image. - Integrate OCR Service: Replace the placeholder API key in the
OCR API by SpaceOCRsticky note with your actual SpaceOCR API key. Configure the node to send the image URL to the OCR service for processing. - Map Transaction Details: In the
Record in Google Sheetsnode, ensure thevaluefields correctly map the parsed data (e.g.,{{ $json.fee }},{{ $json.amount }}) from the OCR output to your desired Google Sheet columns. - Configure Google Sheets Connection: Set up and authenticate your Google Sheets account using the
googleSheetsOAuth2Apicredential. Ensure the target Google Sheet is accessible and has the necessary columns defined.
