A WhatsApp shared inbox is a dashboard where multiple agents can read, assign and reply to WhatsApp conversations from a single business number. Required features include assignment rules, internal notes, tags, conversation history, SLA timers and the 24-hour window indicator.
The WhatsApp Business App allows one device at a time; the API + a shared inbox like Broadcasto allows unlimited concurrent agents on the same number.
Key workflows: round-robin auto-assignment, agent-to-agent handoff, supervisor takeover, internal @mentions, canned replies, tags and bulk actions.
