## Why Delete an Advertiser?

There may come a time when you would like to delete a specific advertiser. To delete an advertiser, simply use the [Update Advertisers API](https://dev.kevel.co/v1.0/reference/advertiser#update-advertisers) endpoint and be sure to set the `isDeleted` boolean value to `true`.

## API Syntax

When using the Delete Advertisers API endpoint, it is important to understand the syntax required to make the request. Because the Kevel API is a RESTful API, there is a specific request format that must be followed to ensure the endpoint can process the request. The format is:

`PUT https://api.kevel.co/v1/advertiser/{AdvertiserID}`

Where:

- `PUT` - the type of API request being made.
- `https://api.kevel.co` - the URL for the request.
- `v1` - the API version.
- `advertiser` - the API endpoint being called.
- `AdvertiserID` - The ID associated with the advertiser being updated.

### JavaScript Code Example

```javascript
const Adzerk = require('@adzerk/management-sdk');
const apiKey = process.env.ADZERK_API_KEY;

async function deleteAdvertiser() {
  let specifications = await Adzerk.fetchSpecifications();
  let client = await Adzerk.buildClient({apiKey, specifications, logger});

let advertiser = await client.run("advertiser", "update", {id: 989963, isDeleted: true});
  console.log(advertiser);
}

deleteAdvertiser();
```

### Ruby Code Example

```ruby
require "adzerk"

def delete_advertiser()
    client = Adzerk::Client.new(ENV["ADZERK_API_KEY"])
    advertiser_id = 12345
    pp client.advertisers.delete(advertiser_id)
end
delete_advertiser()
```
