Create a [Firecrawl.dev](https://www.firecrawl.dev/) account and get your API key\n2. Add your Firecrawl API key to the HTTP Request node's Authorization header\n3. Connect your URL database to the input node (column name must be \"Page\") or edit the array in `Example fields from data source`\n4. Configure your preferred output database connection\n\n## How to Adjust it to Your Needs\n- Modify input source to pull URLs from different databases\n- Adjust rate limiting parameters if needed\n- Customize output format for your specific use case\n\n\nMade by Simon @ [automake.io](https://automake.io)\n"

Create a [Firecrawl.dev](https://www.firecrawl.dev/) account and get your API key\n2. Add your Firecrawl API key to the HTTP Request node's Authorization header\n3. Connect your URL database to the input node (column name must be \"Page\") or edit the array in `Example fields from data source`\n4. Configure your preferred output database connection\n\n## How to Adjust it to Your Needs\n- Modify input source to pull URLs from different databases\n- Adjust rate limiting parameters if needed\n- Customize output format for your specific use case\n\n\nMade by Simon @ [automake.io](https://automake.io)\n"

It could be 1 of various files (json, zip...) accessible via download URL returned by the workflow.\n\nWorkflow can be tested with a PDF filed fetched with Dorpbox for example or any storage provider.

This workflow automates the transcription process in real-time, ensuring that key discussions and decisions are accurately captured and easily accessible for later review, thus enhancing productivity and clarity in communications.\n\nThe workflow leverages n8n and LlamaParse to automatically detect new invoices in a designated Google Drive folder, parse essential billing details, and store the extracted data in a structured format. The key functionalities include:\n- Real-time detection of new invoices via Google Drive triggers.\n- Automated HTTP requests to initiate parsing through Lama Cloud.\n- Structured storage of invoice details and line items in a database for future reference.\n\n1. **Google Drive Integration**: Monitors a specific folder in Google Drive for new invoice uploads.\n2. **Parsing with LlamaParse**: Automatically sends invoices for parsing and processes results through webhooks.\n3. **Data Storage in Airtable**: Creates records for invoices and their associated line items, allowing for detailed tracking."

This workflow automates the transcription process in real-time, ensuring that key discussions and decisions are accurately captured and easily accessible for later review, thus enhancing productivity and clarity in communications.\n\nThe workflow leverages n8n and LlamaParse to automatically detect new invoices in a designated Google Drive folder, parse essential billing details, and store the extracted data in a structured format. The key functionalities include:\n- Real-time detection of new invoices via Google Drive triggers.\n- Automated HTTP requests to initiate parsing through Lama Cloud.\n- Structured storage of invoice details and line items in a database for future reference.\n\n1. **Google Drive Integration**: Monitors a specific folder in Google Drive for new invoice uploads.\n2. **Parsing with LlamaParse**: Automatically sends invoices for parsing and processes results through webhooks.\n3. **Data Storage in Airtable**: Creates records for invoices and their associated line items, allowing for detailed tracking."

There should be a newline after every markdown table.\nFor any graphics, use replace with a description of the image. Images of scanned checks should be converted to the phrase \"<scanned image of check>\"."
