# Digital Services Act
Epsilon Retail Media supports the European Union (EU) [Digital Services Act](https://commission.europa.eu/strategy-and-policy/priorities-2019-2024/europe-fit-digital-age/digital-services-act_en) (DSA) to enhance online transparency and safety. The DSA establishes a unified set of rules across the EU, targeting the regulation of online content, transparent advertising, and disinformation. This document outlines how Epsilon Retail Media assists retailers in meeting their DSA obligations.
The Epsilon Onsite Retail Media platform provides DSA information for all supported ad types, including product ads, banner, and banner X.
## Transparency requirements
To assist retailers comply with the DSA we can provide:
* **Advertiser identity**: The legal entity name of the advertiser.
* **Ad financer identity**: The legal entity name of the party who paid for the ad, if different from the advertiser.
## Ad serving changes
Retailers need to ensure the following:
1. Ensure both the\*\* Company name\*\* and **Ad financer** fields are correctly filled out for all your teams to comply with the DSA. You can specify these details when creating a team using the Epsilon Retail Media UI.
* The **Company name** field is the legal entity name of the advertiser.
* The **Ad financer** field is the legal entity name of the party who paid for the ad.
2. Retailers who need the DSA information must send an additional attribute to retrieve the DSA information in the ad response. The new ad request attribute is sent within the `options` object:
```
"options": {
"includeAdvertiserInfo": true
},
```
The ad response object includes the DSA information:
```
"metadata": {
"advertiserInfo": {
"advertiser": "Test limited",
"onBehalfOf": "Example Inc",
}
```
| Field name | Description |
| ---------------- | -------------------------------------------------------------------------------------------------------------------------- |
| `metadata` | Contains the `advertiserInfo` nested object. |
| `advertiserInfo` | Information needed by a retailer to comply with the DSA in Europe. |
| `advertiser` | Name of the company creating the advertisement for example the agency. This maps to the team's **Company name** in the UI. |
| `onBehalfOf` | Name of the company paying for the ad. This maps to the Team’s **Ad financer** in the UI. |

## Frequently asked questions
Here are some of the frequently asked questions related to the DSA regulations in Europe:
### What if a supplier or retailer changes the `Company name` or `Ad financer` name during a live campaign?
If the `Company name` or `Ad financer` name is changed during a live campaign, all unserved ads and future ad responses will be updated with the new details. It is important to consider the impact on your reporting setup, as the modification might affect the data. Evaluate whether it's worth changing the name or if creating a new team is a better option.
### What if an ad request includes `"includeAdvertiserInfo" = true` but lacks `Ad financer` values?
If an ad request has `"includeAdvertiserInfo" = true` but the `Ad financer` field is missing values, Epsilon Retail Media will still send the ad with an empty string in the Ad financer property. You (the retailer) can then decide whether to display the information or not display it.
### What happens if `"includeAdvertiserInfo" = true` is not included in the ad request?
If `"includeAdvertiserInfo" = true` is not included in the ad request, we do not send the `advertiserInfo` (DSA) information in the ad response.
### What if there's an error retrieving the DSA information for the `metadata.advertiserInfo` object?
If there's an error retrieving the DSA information for the `metadata.advertiserInfo` object, we will still serve the ad but without the `metadata.advertiserInfo` object.
