Introducing Rust School Philippines 🇵🇭 +  Rust School Nigeria 🇳🇬 

We set out to build a different kind of learning experience with Rust and we accidentally created the fastest-growing Rust community on the planet.

Cohort 01 with 1500+ applications in a week proved it.

Now we're going global. 🌍

🧵 Rust School is expanding - and our first two regional hubs just dropped.

INSTANT PAYMENT NOTIFICATIONS (IPN) API by KCB

Kenyan fintech developers - if you've built Customer To Business (C2B) on Safaricom's Daraja, you already understand this pattern. 👇

KCB Buni has an equivalent: the Instant Payment Notifications (IPN) API. A service used to send real-time notifications about payment-related events. It allows businesses or service providers to be informed immediately when certain financial transactions occur, enabling automated processing and updates.

Same concept - your server receives a real-time POST payload the moment a payment hits your account/till. Different rail, direct bank-side execution.

Here's what that looks like in practice:

Safaricom C2B (Daraja):

→ Customer pays to a paybill/till number
→ Safaricom sends a confirmation callback to your endpoint
→ You parse, validate, update your records

KCB Buni IPN:
→ Customer makes payments to a KCB account, Vooma tills or to a Lipa Na KCB till via KCB STK Push or bank transfer
→ KCB sends an IPN payload to your registered endpoint
→ You parse, validate, update your records

The implementation pattern is nearly identical. If you've done one, you can do the other.

Why it matters for your stack:
- Direct bank integration for merchants already banking with KCB Bank Group
- Direct bank integration reduces middleware dependency
- KCB IPN pairs cleanly with their STK Push - one API, full transaction lifecycle

I recently implemented this for a merchant banking with KCB Bank Group. The IPN endpoint handled real-time confirmation, deduplication, and ledger updates - same logic we'd normally wire for Daraja C2B.

If you're building payment infrastructure in Kenya, this is worth knowing.

If you need help integrating KCB Buni IPN, STK Push, or any payment gateway into your product - feel free to reach out. Happy to help.

@gregorytechKE Alright

@gregorytechKE @BrighterMonKE @MyJobMag @LinkedIn @adzuna @KenyaCpk45362 @KenyaRecruiters @Glassdoor @indeed @PigiaMe @SummitRecruitke @talentmatchinc @gregorytechKE at the moment annex scraps and presents job sites as well as opposed to the specific jobs, this might overwhelm the user as it'll redirect to another site thus layers of links before the actual job link is reached
