We gathered every way to connect WhatsApp and Telegram to your CRM in one guide. Setup, how it works and why it matters for Zoho CRM, Bitrix24 and HubSpot — without the WhatsApp Business API.
WhatsApp CRM integration is a bridge that links every inbound and outbound customer message on WhatsApp (and Telegram) to your CRM records (contacts, leads, deals). So every conversation is logged on the right customer card; your sales and support teams chat from one screen, with full history at hand.
FlexInbox delivers this for three major CRMs: Zoho CRM, Bitrix24 and HubSpot. And you never have to set up the WhatsApp Business API — your agent connects their own number by QR.
Customers now write on WhatsApp instead of email or phone. If those messages stay outside the CRM, history is lost, nobody knows which agent said what, and reporting becomes impossible. Integration closes that gap. For more: Why is WhatsApp critical for businesses?
No technical knowledge needed.
Authorize your Zoho, Bitrix24 or HubSpot account in one click; users come in automatically.
The agent connects WhatsApp/Telegram by QR; no Business API required.
Message from the CRM card; assign an AI agent to the line if you like.
What happens behind the scenes the moment a message arrives.
The inbound number is looked up in the CRM; if a record exists it is linked, otherwise it is created based on your mode.
Inbound and outbound messages are written to the customer timeline/activity.
If an AI agent is assigned to the line, it replies automatically; when an operator types, the AI goes quiet in that conversation.
Zoho CRM: Message from the record card, automatic Lead/Contact/Deal creation, owner sync. Zoho users become agents directly.
