What it does
- An approved contact sends a document in WhatsApp.
- The bridge picks it up and runs it through an existing document workflow, the same one used by the web and Telegram versions.
- The finished file is sent back into the same chat.
Nobody installs anything or logs in. The chat they already use is the interface.
Built to be boring
- Only documents from configured contacts are processed. Everything else is ignored.
- The webhook listens only on the server itself and is never exposed to the internet. Pairing data stays on the server.
- Documents are processed one at a time, in order, with retries, so a busy afternoon can't make results arrive mixed up or out of order.
- Missed events are recovered, so a file sent during a restart still gets processed.
Why it matters
The workflow already existed. What was missing was a way in that didn't ask anyone to change their habits. Most automation works better when it meets people where they already are, and in a lot of businesses that place is a chat app.
