### Bid Params

{: .table .table-bordered .table-striped }
| Name          | Scope    | Description           | Example   | Type       |
|---------------|----------|-----------------------|-----------|------------|
| `accountId`   | required | Relay Account Id      | `9778`    | `'number'` |

### Note

The Relay Bid Adapter makes requests to the Relay Exchange API which supports OpenRTB.

Therefore the only bid param required is the the `accountId`, all Prebid Ad Unit fields will be automatically inferred via Prebid's ORTB Converter. If any field on the request requires customization it is configurable using [First Party Data - Prebid.js](https://docs.prebid.org/features/firstPartyData.html#supplying-adunit-specific-data) via `ortb2` interface. We support all FPD fields: site.content.data, site.ext.data., user.data, user.ext.data.
