Coupon service functionality extended by adding cashback function

Goal

The service provided an option to transfer the savings to the charities only. It was necessary to add the option to receive cashback.

Obstacle

There are several types of stores in the marketplace with different cashback and donation policies. Integration with each of them requires different APIs, which complicates the processing of shop events (intermediary’s information on the specific purchase from a specific store).

Solution

We introduced flexible, dynamic bets for each store and defined the cashback and donation policies depending on the type of store. We performed code review and added tests to check the service operation.
