Kajabi

The Kajabi ecommerce integration with UltraCart lets you sell online courses, coaching programs, and membership content through UltraCart's full-featured checkout — automatically granting buyers access to their Kajabi products the moment payment is processed, with no manual fulfillment steps in between.

Kajabi is one of the leading platforms for knowledge entrepreneurs, powering over 100,000 creators who have collectively generated more than $10 billion in revenue since the company's founding in 2010. It provides an all-in-one environment for building and delivering online courses, membership sites, coaching programs, and digital products — complete with built-in landing pages, email marketing, and community features.

Kajabi includes its own checkout, but merchants who need UltraCart's commerce depth — subscription billing with dunning and retry, multi-item carts, upsell and downsell sequences, affiliate tracking, or advanced tax handling — can use UltraCart as the payment engine instead. The integration works through UltraCart's Instant Payment Notification system: when a customer completes a purchase, UltraCart fires a webhook to Kajabi's activation URL, which immediately grants the buyer access to the corresponding Kajabi Offer. If a refund is processed, a deactivation webhook revokes access automatically.

For merchants using the current version of Kajabi, UltraCart also supports a Zapier-based integration path — UltraCart sends a webhook to Zapier, which triggers a Kajabi Offer Grant with the customer's details mapped from the order data. Both methods use UltraCart's per-item IPN configuration, so you can map different UltraCart products to different Kajabi Offers, selling an entire catalog of courses and memberships from a single UltraCart storefront with individualized access control for each product.
