Callbell is a shared inbox for business messaging across WhatsApp, Messenger, Instagram, and Telegram, with conversations carrying a status, an assigned agent, a team, a channel, a contact record, and tags. The Callbell dashboard surfaces conversations as a chronological list with filters by agent and channel, which is correct for agents but limited for cross-channel queue visibility from a WordPress dashboard.

SleekView Kanban authenticates with the Callbell API using your access token and pulls every conversation along with its current status, assigned agent, team, channel, contact name, subject, and last activity timestamp. It groups the records into columns by the conversation status field, so Open, In Progress, On Hold, and Closed each get a swimlane, and any Callbell tag is available as a board filter for cross-channel workflows on the kanban screen.

Dragging a card from one status to another writes the change through the Callbell API. Promoting Open to In Progress routes the conversation, marking In Progress as On Hold parks it with a waiting reason, and moving On Hold to Closed finalizes the conversation. Callbell automations, customer notification rules, business hours logic, and webhook integrations all continue to fire because SleekView calls the same endpoints the Callbell app uses internally for status changes.

Callbell focuses on business messaging across WhatsApp, Messenger, Instagram, and Telegram, with a shared inbox for teams handling these channels at scale. That focus is a strength for messaging-first teams but makes cross-channel queue shape harder to see because the default inbox folds everything into a list with channel as just one filter among many. A kanban view turns the conversation queue into a layout that exposes shape across all the team's channels.

Open is the unassigned incoming volume, In Progress is the active work owned by agents, On Hold is the parked work awaiting customer reply, and Closed is the closed pile. The relative size of those columns answers questions no inbox view ever does at a glance, like whether WhatsApp generates disproportionate On Hold volume because of template approval delays or whether Instagram DMs get stuck in Open because of platform throughput limits. Drag and drop matters because Callbell status changes drive automations, business hours logic, and reporting.
