An emailed invoice becomes a Google Sheets row
DocInspect API inside your n8n workflows: data extraction from documents, no code.
A Gmail trigger catches the email
Fires on an attachment: a PDF, a scan or a photo of an invoice.
DocInspect API reads the document
POST /v1/process with your schema: requisites, line items, totals — plus warnings about mismatches.
IF checks the warnings
warnings empty: the row goes to Google Sheets. A high-severity warning — say, totals that do not match the line items: the document goes to an operator on Telegram.
Available today: the HTTP Request node
