Stripe AI voice agent integration.
Failed payments get a call and a link.

Failed payments start a call

Stripe events such as a failed invoice payment reach Zapier, Make or your code, which asks Kallix to call that customer.

A Stripe link for each customer

Pass the customer's invoice or payment link as a variable, and it goes out on WhatsApp once the call ends.

Paid status flows back

When Stripe reports the payment, update the contact so the customer isn't called again about that invoice.

No card details on the call

Agents never ask for card numbers, OTPs, PINs or passwords. Customers pay on Stripe's own page.
