Connecting Multiple WhatsApp Numbers to a Single Sub-Account in HighLevel CRM

🚀 Overview

This SOP explains how to connect multiple WhatsApp numbers to the same HighLevel sub-account. 

This is useful when:

• You want multiple team members using individual WhatsApp numbers.

• You want to increase message-sending volume across different devices.

✅ Prerequisites

Before starting, ensure the following:

1. WhatsApp Devices Installed & Connected

   • Each WhatsApp number requires a separate connected device.

   • Follow the WhatsApp Installation Guide first.

2. Users Created in Sub-Account

   • Each WhatsApp number must be assigned to a user.

   • Create additional or dummy users if needed.

⚙️ Step-by-Step Setup1. Verify Devices

• Navigate to Devices > WhatsApp

• Confirm that:

  • Your first WhatsApp device is already attached.

  • A second device is connected but not yet assigned.

2. Assign WhatsApp Device to User

• Go to your Sub-Account.

• Click Assign New WhatsApp Device.

• Choose the user you want to assign it to.

• Select the second device.

• Click Assign.

3. Set Messaging Preferences

• Go to Settings > Preferences.

• Set your messaging order:

  • Example: WhatsApp > iMessage > SMS.

  • WhatsApp is prioritized, iMessage is fallback, SMS is the final fallback (if on iPhone).

💬 How Messaging Works with Multiple WhatsApp Users▶️ Automated Messages (Workflows)

• Leads assigned to a user will receive messages from that user's WhatsApp number.

• If a lead is reassigned, future messages will come from the new user's number.

✉️ Manual Messages (Conversation Tab)

• Sent from the logged-in user’s WhatsApp number, regardless of who the lead is assigned to.

To manually send from the correct number:

1. Switch Users:

   • Log in as the user assigned to the lead.

   • Send message manually.

2. Use MultiSIM Message Override (Recommended):

   • Install the myCRMSIM Snapshot.

   • Use the MultiSIM Messaging Override workflow.

   • Messages are automatically sent from the correct user's number, even if you're logged in as someone else.

⚖️ Message Volume Tips

• WhatsApp: ~1 message per minute per device once warmed up.

• iMessage: Up to 50 new recipients per day.

• SMS via Android SIMs: Needed for bulk messaging or reactivations.

Use WhatsApp + iMessage for conversational messages, and WhatsApp + SMS (with Android SIM) for volume/bulk campaigns.
