Everything You Need to Run WhatsApp in Slack

Powerful capabilities designed to let your team handle WhatsApp customer interactions without ever leaving Slack.
Threaded WhatsApp Conversations
Each incoming WhatsApp inquiry opens as a dedicated, organized thread in your designated Slack channel. Keep main channels tidy and conversation history contained.
2-Way Real-Time Messaging
Replies in Slack threads are instantly dispatched to customers on WhatsApp via the official WhatsApp Business API with zero lag.
Private Team Notes (note:)
Need to collaborate internally? Prefix any message with "note:" to keep it private in Slack. WhatsBox adds a 🔒 reaction and never sends it to WhatsApp.
24-Hour Customer Care Window Enforcement
WhatsApp policy allows free-form messaging within 24 hours of customer contact. WhatsBox blocks unprompted text outside the window and alerts you with a 1-click button to open WhatsBox for template sending.
Live Delivery Status Reactions
Know the exact status of every outgoing message right in Slack with automatic emoji reactions: ⏳ (dispatching), ✅ (delivered), 👀 (read), and ❌ (failed).
Media & File Attachments
Receive and send photos, PDFs, documents, audio clips, and videos seamlessly between Slack and WhatsApp customers.

Never Violate WhatsApp's 24-Hour Policy Again

WhatsApp enforces a 24-hour customer service window for business-initiated plain text messages. WhatsBox automates compliance so your team never has to guess.

Within 24-Hour Service Window

Customer contacted you in the last 24 hours

Your team enjoys free-form two-way communication directly from Slack. Type replies, attach media files, share links, and use internal notes without needing pre-approved templates.

  • Unrestricted instant replies from Slack threads
  • Media and document file attachments supported
  • Real-time delivery confirmation reactions (⏳, ✅, 👀)

Outside 24-Hour Service Window

Customer's session has expired

WhatsApp requires an approved Meta template message to re-engage. WhatsBox intercepts plain text replies in Slack, prevents delivery failures, and displays an action button to open WhatsBox and send a template.

  • Automated session expiration warning in thread
  • 1-click button deep-links to the exact WhatsBox chat
  • Keeps your Meta WhatsApp Business account compliant

Get Started in 3 Simple Steps

Connect your Slack workspace to WhatsBox in less than two minutes without technical friction.
01

1-Click Slack OAuth

Connect your Slack workspace directly from your WhatsBox dashboard using standard Slack OAuth v2. No complex API credentials or tokens needed.

02

Select Destination Channel

Pick any public Slack channel during install, or invite @WhatsBox to a private channel (/invite @WhatsBox). All incoming chats route there.

03

Reply in Slack Threads

Receive new WhatsApp conversations as threads. Reply directly, collaborate using internal notes, and track delivery status in real time.

Frequently Asked Questions

Everything you need to know about the WhatsBox Slack Integration.
According to Meta’s WhatsApp Business API policies, businesses can exchange free-form session messages with customers for 24 hours after the customer’s latest incoming message. Within this window, your team can chat freely from Slack threads. If the 24-hour window expires, WhatsBox automatically halts plain text replies and posts an alert card in the thread with an interactive button: "Open in WhatsBox to Send Template Message". Clicking this button takes you directly to the conversation in WhatsBox where you can select and dispatch an approved Meta template to re-engage the customer.
