AI Navigators Bootcamp — Our Own Registration Engine

The Brief

TDA runs the AI Navigators Bootcamp — a two-week AI and critical thinking programme for Abuja teens aged 13–16. With 8 seats per cohort and a founding-rate pricing model, we needed a registration system that could handle dynamic pricing, sibling discounts, partial payments, and Paystack integration — without any of it being manipulable from the browser.

The Pricing Problem

Founding rate (₦395,000) applies to the first 3 paid registrations per cohort. After that, standard rate (₦450,000) kicks in automatically. The rate switch had to be server-side — if it ran in JavaScript, anyone with DevTools open could change what they were charged.

Sibling registration adds a 10% discount on the second child's fee, but disables the instalment option — holding two seats on a 50% deposit in an 8-seat cohort is too much capacity risk. The server enforces this regardless of what the form sends.

What We Built

• Server-side price calculation — price fetched from server immediately before Paystack popup opens
• Paystack verify-and-save — payment reference verified via Paystack API before any DB record is created
• Founding rate counter — counts confirmed paid registrations per cohort, not form submissions
• Sibling flow — full second-child details collected, two separate DB records created sharing one payment_ref
• Automatic waitlist — once 8 seats are confirmed, form switches to waitlist mode without any manual intervention

We are our own most demanding client.

The Result

The system is live at thedigitalagencyltd.com/bootcamp. Founding rate switches automatically at the right moment. Sibling registrations create two full admin records from one payment. No price manipulation is possible — every amount is set and verified server-side.
