API

localhost:8080/bank

This api contains all the crud functions for the bank.

localhost:8080/client

Here we can create a client and check the client's requisite

localhost:8080/payment
  • In order to make a payment, the client must pass authentication.
  • Authentication is implemented with jwt tokens.
  • In order to get a jwt token, you need to knock on the api
localhost:8080/authenticate
  • If the token is valid, you will authenticate and get access to make the payment.
  • If the token is not valid, it will throw an ClientNotFoundException exception.
  • You can make a payment and then cancel your payment if necessary.
  • Also after the payment you have the opportunity to check the status of your payment.

Statuses in project are implemented as enum.

  • If the payment is completed successfully, the status will be SUCCESS.
  • If you don't have enough money on your balance, the status will be a FAILED.
  • If you canceled the payment, the status will be CANCELLED
