# Operate a Workflow

## **Setup Requirements**

* **Set up Inverter Network SDK**: Refer to the[ Quick Start](https://docs.inverter.network/sdk/typescript-sdk) guide for detailed instructions.
* **Deploy a Workflow**: Refer to the[ Deploy a Workflow](https://docs.inverter.network/sdk/typescript-sdk/deploy-a-workflow) 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
```

## Retrieving a Workflow

**Parameters**

1. **`orchestratorAddress` (required)**:\
   The address of the orchestrator responsible for managing the workflow. This parameter must always be provided.
2. **`requestedModules` (optional)**:\
   Suggested to be included for end-to-end TypeScript coverage. This parameter provides additional context or configuration for the workflow's orientation.
3. `useTags` **(optional):**\
   This parameter is to optionally disable auto format parse for inputs and outputs (default true).

```typescript
import { sdk } from '<your_sdk_export>'

const { getWorkflow } = sdk

// Should either be `as const` or be passed dirrectly in the `requestedModules`
const requestedModules = {
    fundingManager: 'FM_DepositVault_v1',
    paymentProcessor: 'PP_Simple_v1',
    authorizer: 'AUT_Roles_v1',
    optionalModules: [
        'LM_PC_Bounties_v1', 'LM_PC_RecurringPayments_v1'
    ]
} as const satisfies MixedRequestedModules

const workflow = await getWorkflow({
    orchestratorAddress: '0x8a1897E6Fa0236F68f86240C391D2a7bED3Cf85c',
    requestedModules
});

const { 
    orchestrator, 
    authorizer,
    fundingManager,
    optionalModule,
    fundingToken
} = workflow
```

{% endcode %}

## Reading Data

You can read data from any of the modules as shown below. In this example, we are retrieving the `totalSupply` of the fundingToken:

{% code overflow="wrap" %}

```typescript
const totalSupply = await workflow.fundingToken.module.read.totalSupply.run();
```

{% endcode %}

## Writing Data

You can write data to any of the modules as shown below. In this example, we are making a deposit to the funding manager:

{% code overflow="wrap" %}

```typescript
const txHash = await workflow.fundingManager.write.deposit.run('100', {
    confirmations: 1,
    onHash: (hash) => {console.log(hash)},
    onConfirmation: (receipt) => {console.log(receipt)},
    onApprove: (receipts) => {console.log(receipts)}
});
```

{% endcode %}
