# Simulate a Workflow

## **Setup Requirements**

1. **Set up Inverter Network SDK**: Refer to the[ Quick Start](/sdk/react-sdk.md) Guide for detailed instructions.

{% hint style="info" %}
*( optional )* You can pass in a ModuleData typed object into the `requestedModules` constant's fields, this makes it so that you can work with your self managed inverter modules
{% endhint %}

```typescript
// EXEMPLE MixedRequestedModules USAGE
import type { ModuleData, MixedRequestedModules } from '@inverter-network/sdk'

const AUT_Roles_v1 = {'<your_module_data>'} as const satisifies ModuleData

const requestedModules = {
    fundingManager: 'FM_DepositVault_v1',
    paymentProcessor: 'PP_Simple_v1',
    authorizer: AUT_Roles_v1,
} as const satisfies MixedRequestedModules
```

## Simulating the Workflow

All we have to do is decide on the `requestedModules` and we can display or use the output of the simulation. This simulation lets us retrieve the preliminary addresses of a workflow before it is deployed.

**Parameters**

* **`requestedModules` (required)**:\
  This parameter defines the modules which will be deployed.
* `args` **(required)**:\
  This parameter is the arguments for simulated workflow deployment.
* `useTags` **(optional):**\
  This parameter is to optionally disable auto format parse for inputs and outputs (default true).
