What is PAaS-lib?

Payment Application as Service is Westpay's solution for running Android apps on our payment terminals.

So, how does it work?

The process is fairly simple and straight forward:

  • After system boot the terminal performs a few automatic checks and once ready starts the Westpay Payment Application (PA)
  • Once ready, the PA launches your App and hands over the control of the device to You and then goes into idle
  • When your App starts you supply the PA with a set of instructions that later will be used to perform payments
  • Your App is now in control of the terminal and can be used to operate your application without any restrictions
  • When ready, your App sends a request to the our PA via the PAaS lib to perform payments
