# CurrencyController

**Kind:** Controller

**Source:** `Pams/API/Pams.API/Controllers/Common/CurrencyController.cs` (line 20)

**Part of:** [Pams](subsystem-pams)

## Where it refuses work

- `CurrencyController` stops the work with an early return when `string.IsNullOrEmpty(fromCurrency) || string.IsNullOrEmpty(toCurrency)`.
- `CurrencyController` stops the work with an early return when `fromCurrency == 0 || toCurrency == 0`.

## When something fails

- `CurrencyController` handles failure in 3 places: it turns it into a return value in all 3.
