# DELETE - Remove

The App Data API enables you to create, update, delete and list data you associated to your application. **App Data** lets you create **tables** of key/value pairs. It is for **application** centric data as opposed to **user** centric data. You can use the data in your targeting queries and/or in a message template.

### Request structure

#### Route

The App Data API exposes a DELETE endpoint that allows to delete a **table**:

`https://api.batch.com/1.0/BATCH_API_KEY/app-data/TABLE_NAME`

Here is a valid cURL example:

```bash
curl -H "Content-Type: application/json" -H "X-Authorization: BATCH_REST_API_KEY" -X DELETE "https://api.batch.com/1.0/BATCH_API_KEY/app-data/TABLE_NAME"
```

The `TABLE_NAME` value must be a string that only contains letters, numbers or the following characters: `_`, `-`.

**NOTE**: Make sure before deletion that this App Data table is not used by any campaign.

The `BATCH_API_KEY` value is either your **Live**, **Dev** or **SDK** Batch API key from the settings page of your app within the dashboard (⚙ Settings → General).

#### Headers

In order to authenticate with the API, you need to provide your **company REST API Key** as the value of the `X-Authorization` header. You can find it in ⚙ Settings → General.

### Responses

#### Success

If the call to the API endpoint is successful you will receive an **HTTP 200** confirmation and an empty json payload.

#### Failure

If the POST data does not meet the API requirements you will receive an actionable error message. Contact us at <support@batch.com> if you need further support.
