# Advertiser API

> Reference documentation for the Advertiser API

The Advertiser API provides advertiser-scoped access to the Everflow platform. It allows advertisers to view their offers and access reporting data. This API is scoped to a single advertiser's data and permissions.

## Authentication

Advertiser API keys are found in the **API** tab of the **My Account** section within the Everflow UI. All Advertiser API endpoints use the `X-Eflow-API-Key` header for authentication. See [Authentication](/user-guide/authentication) for more details.

## Base URL

```
https://api.eflow.team/v1/advertisers
```

EU-hosted accounts use `https://api-eu.eflow.team/v1/advertisers` instead.
