<a name="grid-bidder-config"></a>

### Bidder Config

You can allow writing in localStorage `pbjs.setBidderConfig` for the bidder `grid`

```javascript
pbjs.setBidderConfig({
    bidders: ["grid"],
    config: {
        localStorageWriteAllowed: true
    }
})
```

If it will be "true" this allow TheMediaGrid Bid Adapter to write userId in first party localStorage

<a name="grid-first-party"></a>

### First Party Data

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

Global site or user data using `setConfig()`, or Bidder-specific using `setBidderConfig()` supports following fields:

- `ortb2.user.data[]`: Standard IAB segment taxonomy user data
- `ortb2.user.ext.device`: Non standard arbitrary user device
- `ortb2.user.keywords`: Standard IAB OpenRTB 2.5 user.keywords field. It will be included in ext.keywords.user.ortb2
- `ortb2.site.keywords`: Standard IAB OpenRTB 2.5 site.keywords field. It will be included in ext.keywords.site.ortb2
- `ortb2.site.cat[]`: Standard IAB OpenRTB 2.5 site.cat field. It will be sent as part of site.cat array
- `ortb2.site.pagecat[]`: Standard IAB OpenRTB 2.5 site.pagecat field. It will be sent as part of site.cat array
- `ortb2.site.content.genre`: Standard IAB OpenRTB 2.5 site.content.genre field

AdUnit-specific data using `AdUnit.ortb2Imp` supports following fields:

- `ortb2.imp[].ext.data.*`
- `ortb2.imp[].instl`

      "assets": [
        {
          "id": 1,
