# Deposit / Withdraw Funds via ACH

## Overview

This POST endpoint enables you to deposit or withdraw funds to/from an ACH-based banking account.

There are five required parameters that must be provided in the request:

1. **Et-App-Key** (header). This is the unique key of your app that identifies your app when communicating with our service. Contact your administrator to get this key.
2. **Authorization** (header). This is the authorization token from the very first [token request](/rest-api/trading-api/authentication.md).
3. **API version** (path). Unless necessary, leave it at "1.0".
4. **accountId** (path). This is the [internal identifier](/rest-api/trading-api/user-accounts/list-users-accounts.md) of the trading account in Autoshares Trader.
5. **model** (body). This is a JSON file containing detailed information about the funds transfer.

### Body Syntax

The body of the request represents a JSON file containing all required parameters for performing a funds transfer.

| Parameter         | Description                                                                                                                                        |
| ----------------- | -------------------------------------------------------------------------------------------------------------------------------------------------- |
| AchRelationshipId | This is the ACH relationship through which the transfer will be performed.                                                                         |
| Amount            | This is the amount of funds to be transferred. The value must be provided in US dollars.                                                           |
| CloseAccount      | This boolean value indicates if the trading account must be closed after the transfer if performed. Only applicable to withdrawal operations.      |
| DaysToHoldFunds   | This is the number of days by which the transfer must be delayed.                                                                                  |
| IsIncoming        | This boolean value indicates the transaction type. To perform a deposit, set it to `true`. Conversely, to perform a withdrawal, set it to `false`. |

For example:

```javascript
{
   "AchRelationshipId":"91fde713-6c64-4ef3-0606-08d7bacaad26",
   "Amount":50,
   "CloseAccount":false,
   "DaysToHoldFunds":0,
   "IsIncoming":true
}
```

Here's the final template for this API request:

```
POST apiURL/v1.0/accounts/{accountId}/transfers/ach
```

## Response

In response to this API request, you will receive a JSON dictionary containing detailed information about the transfer.

```javascript

## Common Mistakes

Here are some of the common mistakes that developers make when attempting to send a request to deposit or withdraw funds.

### Failing to Specify the Et-App-Key Parameter

If you specify the wrong Et-App-Key parameter or fail to include it in the header altogether, you'll get the following error:

```javascript
{
    "error": "Application key is not defined or does not exist"
}
```
