How I connected SAP Business One to WhatsApp using AI agents (open-source)

I built an open-source agent runtime that connects AI to SAP B1 via WhatsApp The problem I was solving I work as a SAP Business One consultant.

So I built Capyra: an autonomous agent runtime that lives in WhatsApp and acts on business systems directly. What it does Your team sends a WhatsApp message: "How many open orders do we have today?"
