## Wallet API

An implementation of a Wallet API built on Akka Typed making using of event sourcing (using the JDBC plugin) and 

distributed by Akka Cluster Sharding.

Deposits and Withdrawals follow a fee structure (the more money in your account, the cheaper it becomes to transact).

The amount of money generated by fees is calculated via a Persistence Query but is not currently exposed but can be 

accessed by querying the `processor` table.

### Running the application

1. Make sure to spin up Postgres via `docker-compose up -d`

2. Run the application using IntelliJ, Visual Studio Code + Metals or just `sbt run`

### Postman

A Postman collection is included for easy testing in the `postman` folder

### Operations

#### Create 

`POST /wallets`

```json

{

  "id": "abc"

}

```

#### Deposit

`POST /wallets//deposit`

```json

{

  "amount": 2000

}

```

#### Withdraw

`POST /wallets//withdraw`

```json

{

  "amount": 2000

}

```

}

```
