Each user interface has different fields pertinent to their unique purpose. For example, we have a Property Details Layout for Conveyancing Matter Types:

Data Mapping

How to get a list of layout fields that you can set up a mapping for:
  1. Get a reference for the layout design ID by querying a matter type.
GET https://api.smokeball.com.au/mattertypes/{matterTypeId}
Example response: 
{

  "href": "https://api.smokeball.com.au/mattertypes/9c6f59b6-3871-4fbd-a508-8fc43f03c6b4",

  "items": [
    {
      "href": "https://api.smokeball.com.au/layouts/b571beb4-9175-436c-a70e-e70acb0f4ed2",
      "rel": "layouts",
      "id": "b571beb4-9175-436c-a70e-e70acb0f4ed2",
      "providerId": "LayoutProvider",
      "name": "Workers Comp Details"
    }
  ],
  "id": "9c6f59b6-3871-4fbd-a508-8fc43f03c6b4",
  "versionId": "1bd57eaa-089c-4a92-8136-aed74bf5c389",
  "name": "Workers Compensation",
  "category": "Personal Injury",
  "representativeOptions": [
    "Worker",
    "Employer"
  ],
  "location": "NSW"
}
In this example, /items/0/id contains the layout design ID and /items/0/href contains a full URL to use in the next step.
  1. Retrieve the full list of fields for the given layout design.
GET https://api.smokeball.com/layouts/{layoutDesignId}
Example response: 
{
  "id": "b571beb4-9175-436c-a70e-e70acb0f4ed2",
  "href": "https://api.smokeball.com.au/layouts/b571beb4-9175-436c-a70e-e70acb0f4ed2",
  "fields": [
    {
      "name": "Matter/WorkersCompDetails/BodyPartInjured",
      "type": "Text"
    },
    {
      "name": "Matter/WorkersCompDetails/DateOfInjury",
      "type": "DateTime"
    },
    {
      "name": "Matter/WorkersCompDetails/DescriptionOfInjury",
      "type": "Text"
    }
  ],
  "name": "Workers Comp Details"
}
In this example, /fields/*/name contain the layout fields that you can set up a mapping for.
