The problem
Kajabi already manages the coaching programme and billing, but the member experience needs personal weight and calorie records, progress charts and tailored follow-up. The difficult boundary is identity: a person can register before purchasing, arrive from a lesson or return through an email, while membership status changes independently.
A missed membership update must not leave the tracker permanently out of step with Kajabi, and a cancelled subscription should not be confused with an invalid login.
The solution
SlimFits adds a dedicated tracking application while keeping Kajabi responsible for courses and subscriptions. It links members across the two systems, separates sign-in from permission to use a course tracker, and combines membership webhooks with a daily reconciliation against the Kajabi API.
Personal progress records drive charts and weekly emails. The integration supports both the standalone experience and the Kajabi entry path without turning a member identifier into proof of identity.
The decisions behind it
- Identity is not entitlement
- Knowing who a member is and knowing which course they can access are separate checks. A subscription change should update access without breaking the person's account.
- Events plus reconciliation
- Webhooks provide prompt membership updates; a scheduled comparison repairs missed events rather than assuming every notification arrived.
- Kajabi membership synchronisation
- Member tracking and progress charts
- Personalised weekly email workflows
