Using 1st-party sales data directly from the retailer, Epsilon Retail Media delivers targeted, relevant, and personalized ad content to the retailer's e-commerce server in the form of a product code every time a new page loads.
The Epsilon Retail Media API allows you (the retailer) to place ads on your e-commerce website. Once you define ad placements on your site, they become available for advertisers to bid on.
Simply put, Epsilon Retail Media allows advertisers to create ad campaigns that run on each retailer's e-commerce website. Advertisers bid to promote their products at the top of the retailer's site, and can track the performance of their products in real time.
Our user-friendly admin portal allows advertisers to choose the products, budgets, ad strategies, and search terms for the products they want to feature at the top of the retailer's e-commerce site.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://help.citrusad.com/retail-media-interface/integration/hu/getting-started/overview.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
