## Bid Params

{: .table .table-bordered .table-striped }
| Name          | Scope    | Description                | Example                                   | Type      |
|---------------|----------|----------------------------|--------------------------------------     |-----------|
| `tagId`       | required*| Media Tradecraft tag ID    | `"textmtrc"`                              | `string`  |
| `placement`   | required*| Media Tradecraft placement | `"test.com_header_ad"`                    | `string`  |

*You *must* only include one ID field - either `tagId` or `placement`, not both. If you have questions on which parameter to use, please reach out to your Account Manager.
The `tagId` and `placement` are **mutually exclusive** but at least one is required. If you pass both, `tagId` takes precedence.

## Bidder Config

You can allow writing in localStorage `pbjs.bidderSettings` for the bidder `mtc`

{% include dev-docs/storageAllowed.md %}

```javascript
pbjs.bidderSettings = {
    mtc: {
        storageAllowed : true
    }
}
```

## First Party Data

Publishers should use the `ortb2` method of setting [First Party Data](https://docs.prebid.org/features/firstPartyData.html).
