This integration uses the Ideal Postcodes Extension which can be downloaded from the Chrome or Firefox Extensions marketplaces.

See our Browser Extension guide for more information.

Custom Objects

Creating Custom Objects

  1. On the Contacts page click 'Actions'.

  2. Choose edit properties.

  3. Create a property.

  4. Choose the object type and group.

  5. Name your object - this will be used to reference the object in the JSON configuration editor.

Creating Custom Objects


If you are looking to add additional address elements, you will need to assign a custom object for line_1.
It will not work otherwise.

Setting up

The Browser Extension also allows you to bind Address Finder to additional address attributes. To do this you will need to map an address field to a Custom Object Field Name using our JSON configuration editor.

"line_1": "textarea[data-selenium-test='property-input-line_one']",
"line_2": "textarea[data-selenium-test='property-input-line_two']",
"line_3": "textarea[data-selenium-test='property-input-line_three']",
"post_town": "textarea[data-selenium-test='property-input-city']",
"postcode": "textarea[data-selenium-test='property-input-zip']",
"uprn": "textarea[data-selenium-test='property-uprn']",
"organisation": "textarea[data-selenium-test='property-input-organisation-name']"

The complete list of address fields (e.g. line_1, post_town, postcode) is available in our data documentation.
