Before configuring WhatsApp messaging inside Vtiger CRM, ensure the following requirements are met:
Active Vtiger CRM instance

Once connected, the CRM can send and receive WhatsApp messages securely.
WhatsApp requires pre-approved templates for outbound notifications.
Common template use cases include:

Templates can include dynamic CRM merge fields such as customer name, order ID, or due date.
Navigate to a Lead or Contact record inside Vtiger CRM.
If a valid phone number exists:
Select the WhatsApp messaging option
Choose a template or compose a message
Send instantly
The message is logged automatically inside the CRM record for future reference.
One of the most powerful features of Vtiger WhatsApp integration is automation.
Using Vtiger workflow rules, you can trigger WhatsApp messages based on CRM conditions.
Examples:
When lead status changes to “Qualified”

This transforms WhatsApp into a fully automated CRM communication channel.

All message history remains centralized, improving collaboration and tracking.
