How to Connect Slack to WhatsApp with DMHub

Your team lives in Slack. Your customers live on WhatsApp. Without a bridge, someone has to monitor DMHub's inbox constantly, switching between tools and losing context. DMHub's Slack integration brings WhatsApp messages into Slack channels where your team already works.

What the Integration Does

• New WhatsApp messages appear in a dedicated Slack channel
• Reply from Slack and the message goes to the customer on WhatsApp
• Assignment notifications when a conversation is assigned to a team member
• Escalation alerts for urgent or VIP conversations
• Daily digest summarizing WhatsApp activity

Step-by-Step Setup

Step 1: Connect Slack

1. Go to Settings > Integrations > Slack in DMHub
2. Click Add to Slack and authorize
3. Select the workspace and channel for notifications
4. Configure which events trigger Slack messages

Step 2: Configure Notification Channels

Create dedicated Slack channels for different message types:

• #whatsapp-support — all incoming customer messages
• #whatsapp-sales — new lead conversations
• #whatsapp-urgent — VIP customers and escalated issues
• #whatsapp-daily — end-of-day summary

Step 3: Enable Reply from Slack

With reply-from-Slack enabled, team members can respond to WhatsApp messages directly in the Slack thread. The response is sent to the customer on WhatsApp, and the conversation context stays in both DMHub and Slack.

Step 4: Set Up Smart Routing

Configure which WhatsApp conversations go to which Slack channels:

• By topic: Sales inquiries to #sales, support to #support
• By language: Spanish conversations to #team-latam, Arabic to #team-mena
• By priority: High-spend customers to #vip
• By assignment: Each team member gets a DM when assigned

Use Cases

Remote support team: WhatsApp customer messages flow into Slack. The first available agent replies from their laptop. The customer sees a WhatsApp message. Nobody needs to have DMHub open.

Sales team: New leads from WhatsApp appear in #sales with the customer's profile. The SDR can qualify and respond without leaving Slack.

Management: A daily digest in #whatsapp-daily shows total conversations, average response time, resolved issues, and open tickets. The manager gets visibility without monitoring the inbox.

Multi-location business: Each location has its own Slack channel. WhatsApp messages from customers associated with that location route to the right team.

Response Time Impact

Teams using the Slack integration respond to WhatsApp messages 3.2x faster than those using DMHub's web inbox alone. The reason: Slack is always open. The web inbox isn't.

• Without Slack integration: Average first response time of 23 minutes
• With Slack integration: Average first response time of 7 minutes

For customer support, that difference translates to 28% higher satisfaction scores.

Getting Started

Slack is where your team works. WhatsApp is where your customers are. DMHub bridges them so your team can respond to customers without switching tools, and customers get faster, better service.
