PROGRAMMING TASK¶ ↑

PREFACE¶ ↑

Implement a simple API that allows to validate bonus codes for pre-sale program. Given a set of products with title attribute. Each product has a set of bonus codes assigned. These bonus codes may be either pre-loaded into the system or not. When user enters a bonus code we need to validate it to check that bonus code has been purchased. For some products a third-party service can be used for validation. There are 2 types of such services(but may be more in future). Each product can be linked to a particular service.

There is no need to implement a complete wrapper for a third-party API. A dummy on is enough. Full test coverage is required.
