Connects through WhatsApp Business
What Kallix and WhatsApp do together.
- Follow-ups as the call ends
- Set the message for each agent in the studio. It goes out through WhatsApp Business once the call is over, so the customer has what was agreed in writing.
- A payment link for each account
- Send each customer or borrower a link of their own, such as a UPI link, taken from your contact list. Agents never ask for card numbers or OTPs on the call.
- Documents and confirmations
- Share a booking confirmation, a brochure, a price list or a statement, so nothing depends on the caller remembering what was said.
- Filled from the call's variables
- Names, amounts, dates and order numbers come from the same variables the agent used on the call, such as {{callee_name}} and {{due_amount}}.

No. Agents never ask for card numbers, OTPs, PINs or passwords. They send a payment link on WhatsApp instead, and the customer pays in their own app.
