```
fun setDecisionLogicUri(decisionLogicUri: Uri): AdSelectionConfig.Builder
```

**Deprecated:** *Deprecated in Java.*

Sets the URI used to fetch decision logic for use in the ad selection process. Decision URI could be either of the two schemas:

- **HTTPS:** HTTPS URIs have to be absolute URIs where the host matches the `seller`
- **Ad Selection Prebuilt:** Ad Selection Service URIs follow `ad-selection-prebuilt://ad-selection/<name>?<script-generation-parameters>` format. FLEDGE generates the appropriate JS script without the need for a network call.

  Available prebuilt scripts:
  - **`highest-bid-wins` for `scoreAds` and `reportResult`:** This JS picks the ad with the highest bid for scoring. For reporting, the given URI is parameterized with `render_uri` and `bid`. Below parameter(s) are required to use this prebuilt:
    - **`reportingUrl`:** Base reporting uri that will be parameterized later with `render_uri` and `bid`

    Ex. If your base reporting URL is "https://www.ssp.com" then, `ad-selection-prebuilt://ad-selection/highest-bid-wins/?reportingUrl=https://www.ssp.com`
