I thought AGP would be on 10+ by now. Maybe they did not give in to the sloperators after all.

Do you devs hate intro and explainer video or getting a designer is the problem or you guys think it expensive to have one! I create such videos for Playstore.

When I get a 200 from the request, I create a pending transaction with the checkout request id. I match incoming callbacks against it. This also helps with manual queries if the callbacks fail to arrive. We’ll still acknowledge receipt of the Webhook even if we failed to match it to any transaction. You can take this further by adding auth tokens to the callback urls, whitelist IP addresses but, if you can guess the merchant request ID that is in a pending transaction, you deserve the spoils of the loot.
When you send the Express request, you get the two unique values. MerchantRequesrID and CheckoutRequestID. These are your first line of defence. Validate your webhooks against them. It should match at lease one record with this. Daraja is well designed even though they don’t follow webhooks best practices like signing payloads. But you have to understand, a lot of what Mpesa Express is, is unique to what most of the industry does. Also rate limit failures.

This year, I’m skipping the trip to Uganda for #DroidconUg, as much as I’m a speaker. It came a little too early, and I need time to rest after #StanChartMarathon 2026. Besides, I can’t afford the fare right now. It’s not yet the end month! 😂 So, I’ll do my session virtually.

Developers, this is for you. please take your payment callbacks seriously. 🔐 Yesterday, out of curiosity, I tested an M-Pesa integration on a critical live system. To my shock, I was able to submit a crafted payload that resulted in a payment being marked as successful. Never trust a payment callback blindly. Best practices: - Verify callbacks against the payment provider. - Validate the Merchant Request ID and transaction details. - Verify payment status independently where possible. - Restrict callback access by IP where supported. - Make callbacks idempotent to prevent duplicate processing. - Never mark a payment as successful based on an unverified payload. One weak payment integration can undermine the integrity of an entire system. Security is not just about protecting your APIs. It's about protecting the business logic behind them. 🔒

Understanding is the noblest of pursuits. People who actively strive to understand are pushing against uncertainty. People who give up on understanding are willingly falling into chaos.

I shot a friendship shot to the guy who hacked my startup in 2014, @its_eknock....🥲 Since then he's been teaching LO1 and I how to code; LO 1's year 11 project is a ticketing app for school attendance! Mimi, I am creating the app I always wanted. Iron sharpens iron🙏

A very memorable film I watched it a few months ago and the scenes are still fresh in my head. When my schedule clears up, I’m definitely revisiting this one
