# Delete an ACH Relationship

## Overview

This DELETE endpoint enables you to delete an existing ACH relationship from a particular trading account.

There are six 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 to which the ACH relationship is bound.
5. **id** (path). This is the ID of the to-be-deleted ACH relationship in Autoshares Trader.
6. **reason** (query). This is a string that contains the reason for closing the ACH relationship.

Here's the final template for this API request:

```
DELETE apiURL/v1.0/accounts/{accountId}/ach-relationships/{id}?reason=Closed%20the%20banking%20account
```

## Response

In response to this API request, you will receive a JSON dictionary containing information about the deleted ACH relationship, including the **Canceled** status and the cancelation reason.

```javascript

## Common Mistakes

Here are some of the common mistakes that developers make when attempting to send a request to delete an existing ACH relationship.

### 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"
}
```
