try checking http://www.pesapi.com, there is a howto on the site, i have used it and it works great.

Lipa na Mpesa is a kopokopo service if i am not wrong, you can also log into the kopokopo control panel and enable the http push notification which in my opinion is faster compared to the pesapi api which depends on the mpesa sms being received into an android phone first before smssync pushes it to the api. http push notification is faster and secure especially when done with SSL/TLS and adding authentication to it. i have attached the kopokopo API pdf.

thanks,

Lucas.

You may want to download their API developer guide and take a look at the 'C2B Online Checkout' one.

Any leads on how to make a web application communicate with MPESA with a bias to Lipa na MPESA?
