Automated PDF Processing and Email Notification Workflow

This n8n workflow automates the processing, analysis, and communication of invoice PDFs. It begins with receiving an input (e.g., form submission or webhook), then downloads a PDF file and retrieves a signed URL from Mistral for secure access. The workflow extracts invoice details via an HTTP request, processes the data with AI language models for interpretation, and generates formatted Markdown content. The processed information can be further analyzed or summarized using AI models like OpenAI or Mistral. Finally, the workflow sends email notifications through Gmail and Telegram, providing updates and confirmations to users. Practical uses include automating invoice handling, document analysis, and real-time notifications in business operations.
