Automatically generate and send unique Whop promo codes after Kajabi purchases

This template sends a Whop promo code after a Kajabi purchase. Point Kajabi purchase webhooks at a Latenode webhook.

JavaScript reads the buyer email and product, creates a promo through the Whop API, then Gmail sends the code. Connect Gmail. Put the Whop API key in that JavaScript node.

How Latenode estimates time and cost

Latenode bills workflow runtime in CPU seconds. The first 10,000 CPU seconds are free each month, then usage follows pay-as-you-go CPU-second pricing. Plug-and-Play (PnP) AI nodes are billed separately—each PnP token is $1 USD, charged pay-as-you-go at vendor cost plus a small processing fee, with no API keys required.
