# Proposed Lead Data

Given the opaque nature of JSON data the following could work nicely as an alternative allowing effective introspection.

```gql
type Lead {
  ...
  data: LeadData
}

interface LeadData {
  firstName: String
  lastName: String
  email: String
  phone: String
}

type Buyer implements LeadData {
  firstName: String
  lastName: String
  email: String
  phone: String
}

type Seller implements LeadData {
  firstName: String
  lastName: String
  email: String
  phone: String

  address: String
  city: String
  state: String
  zip: String
  numBedrooms: Integer
  numBathrooms: Integer
}
```

This would allow us to query like so:

```gql
query {
  lead(nodeId: "123") {
    data {
      firstName
      lastName
      email
      phone
    }
    ... on Seller {
      address
      city
    }
  }
}
```
