This project provides a sample PaymentsGateway, which would accept payments requests from a merchant and communicate with a 3rd-party API to do the actual payouts
- src
- PaymentsGateway Project
- AcquiringBank Project (dummy service, which returns successful/uncessful payment request based on probability calculation - 60% success rate to easily simulate both scenarious)
- test
- PaymentsGateway.UnitTests Project
- API Versioning
- Request Caching
- Request Rate Limit
- On Start Swagger UI is loaded
It has the following tables:
- Payments (keep track of the payment transactions)
- PaymetCards (store card information)
- PaymentIssuers (store a record of available issuers such as Visa, MasterCard, etc.)
- Currencies (store a record of available currecies such as GBP, USD, etc.)

}When the application is ran the two projects in the source folder are going to be launched.
- The AquiringBank project can be removed and replaced by an actual service
- Card Numbers should be encrypted if they are stored in database
- Parameters for Http requests can also be encrypted
- Logging Should be added
- Authentication Should be added
- More functionality can be exposed through additional endpoints to manage Currencies, CardIssuers, Payments, PaymentCards, etc.
