## GrowthCode User ID Submodule

GrowthCode provides Id Enrichment for requests.

## Building Prebid with GrowthCode Support

First, make sure to add the GrowthCode submodule to your Prebid.js package with:

```
gulp build --modules=growthCodeIdSystem,userId
```

The following configuration parameters are available:

```javascript
pbjs.setConfig({
  userSync: {
    userIds: [{
      name: 'growthCodeId',
      params: {
          customerEids: 'customerEids',
      }
    }]
  }
});
```

### Sample Eids
Below is an example of the EIDs stored in Local Store (customerEids)
```json
[
   {
      "source":"domain.com",
      "uids":[
         {
