DrillDown

Drill down further into search results

Live Demo

To connect to this service you'll need to use one of these endpoints:

JSON

Open API

SOAP

Description

The drill down method should be used to further narrow down container level results such as towns or streets etc.

Parameters

The following parameters can be supplied to this method

username	username See the available authentication methods. If you are using username & password authentication, specify the username to authenticate as. If you are using API Key authentication and you are not using the JSON, Javascript or ADO APIs, use your API Key here with the prefix `apikey-`, e.g. `apikey-ABCD-1234-EFGH-5678`
password	password If you are using username & password authentication, specify the password to use for authentication. Otherwise leave this blank.
country	country The ISO 2-character country code of the search i.e. "GB"
id	id The `value` property from the response of previous requests from either the Search or DrillDown methods should be supplied here.
options	options An array of options that control further details of how this method operates. See the Advanced Options section below for more information.

Advanced Options

The following options can be specified as part of the option parameter. Each option is specified as a key/value pair. The list of available names is shown below, along with a description of the allowable values for that name.

Common Options
Name	Description
ApplicationName	ApplicationName Gives the name of the calling application - used to break down usage by application in the usage reports on the dashboard
Service-Specific Options
Name	Description
IncludeMR	IncludeMR Includes addresses from the Multiple Residency database in the results (requires additional licensing).
IncludeNYB	IncludeNYB Includes addresses from the Not Yet Built database in the results (requires additional licensing).
PreferredLanguage	PreferredLanguage Set this to `cy` to retrieve addresses in Welsh where available, or `en` to prefer English. Addresses are returned in English when this option is not specified.

Results

This method returns an object containing the following fields:

Status	Status Indicates whether the method call was successful, or if some error occurred. If the `Success` field is `true`, the other results described below can be used to get the results of the method. If `Success` is `false`, some error occurred in calling the method, such as the authentication failed or the account is out of credits. The details of the error can be obtained from the `ErrorMessage` field, and any other results should be ignored
Results	Results A list of possible matches. Each one has the following properties: `label` - the value to show to the user. `value` - a unique identifier for the match that can be supplied to the `DrillDown` or `Retrieve` endpoints. `container` - indicates if this match is a container for other addresses (e.g. a town, street etc.). If this is true, the `value` should be supplied to the `DrillDown` endpoint to get the details of the addresses in the container record. If it is false, the `value` should be supplied to the `Retrieve` endpoint to get the full details of the address.
Count	Count The number of matches found based on the information provided.
SessionID	SessionID A SessionID is also included in the response. This should be included in any subsequent calls to the `Search` endpoint.
