Mpesa

Welcome to mpesa API gem. The gem defines the API resources and helps developers to make requests cleanly.

When you receive a JSON response from an API endpoint, it's really easy to convert this to a Ruby hash. But hashes don't feel very Ruby-ish when you're working with them.

To help on this gem parse the responses to OpenStruct Objects so a developer can interact with the response just like regular ruby objects we are used to.

This Gem provides an interface that developers can use to convert JSON to OpenStruct objects, this is useful when you want to parse results callbacks data.
