Purchase an address for a UPRN

Note: Applies to client version 1.1.X

Ordnance Survey UPRN is a unique identifier for all addressable properties in the UK.

In order to purchase the available variables from the catalog for a particular address, you first need that Postal Address.

Use UPRN to purchase a Postal Address:

// 10 Downing Street, London, SW1A 2AA
var postalAddresses = await client.PurchasePostalAddressesAsync(new UniquePropertyReferenceNumber(100023336956));

Once you have a Postal Address you can then purchase variables from its catalog:

var variableIdentifiersToPurchase = new List<VariableId>
{
    new VariableId("...first variable identifier..."),
    new VariableId("...second variable identifier...")
};
var purchasedVariables = await client.PurchaseVariablesAsync(postalAddress.CatalogId, variableIdentifiersToPurchase);
