## Why Update Advertisers?

Occasionally, you may need to make changes to an existing campaign or flight. The Update Advertisers API endpoint enables you to update the settings for a given advertiser, allowing you to make edits and changes quickly and easily, without creating a new advertiser.

> You can update all fields from Creative Advertisers except for `id`.

## API Syntax

When using the Update 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.

> ❗️
>
> ### Warning  
>
> Once you set `IsDeleted` on an advertiser object to `true`, you cannot set it to false `again`. Instead, the API will return: `{"message":"This advertiser is deleted."}`.

> 📘
>
> ### Clearing attribute values  
>
> To unset or clear an attribute, set its value to `NULL`.
