Request GET /.json
Response 200

Body:

Polling Station Finder 

The /postcode and /address endpoints find a user's polling station based on their home address. This allows you to leverage Democracy Club's data to integrate a polling station finder into your website or app.

A 200 OK response from /postcode or /address is an object containing the following top-level keys:

  • polling_station_known: (boolean) - Do we know where this user should vote?

  • postcode_location: (object, nullable) - A GeoJSON Feature containing a Point object describing the centroid of the input postcode.

  • polling_station: (object, nullable) - A GeoJSON polling station feature

  • addresses: (array) - An array of address objects listing the addresses applicable to this request (if necessary).

  • council: (object, nullable) - A Council object describing the local authority which covers this postcode. If we do not know the user's polling station, this can be used to provide contact info for their local council. Council may be null if we are not able to determine the user's council.

  • custom_finder: (string, nullable) - If we don't know a user's polling station, sometimes we can provide the URL of a polling station finder provided by their local council.

  • report_problem_url: (string, nullable) - If we provide a polling station result, this URL may be used to provide a user with a back-channel to report inaccurate data.

  • metadata: (object, nullable) - This field may be used to supply additional information about an election, particularly if there is some unusual condition or event for voters to be aware of.

  • ballots: (array) - An array of ballot objects listing the elections applicable to this request. It is possible for more than one ballot to occur on the same date. For example, a user may vote in a local council election and mayoral election on the same day. If ballots is an empty array [], there are no upcoming elections in this area.

The entry point to a polling station search is a call to the /postcode endpoint. A valid postcode search may result in one of 3 outcomes:

  • Result found: We hold data for this area and all voters with this postcode vote at the same polling station.

  • Address picker: We hold data for this area but voters with this postcode don't all vote at the same polling station. To find the user's polling station, we must make a second API call to the /address endpoint.

  • Result not Found: We do not hold data for this area.

Postcode search: Result found 

/postcode/{postcode}.json
Example: https://wheredoivote.co.uk/api/beta/postcode/SW1A1AA.json

Parameters

  • postcode string ( required )

    Whitespace in postcodes is ignored, so format may be SW1A1AA or SW1A 1AA

    Example: SW1A1AA

Response 

When we hold data for this area and all voters with this postcode vote at the same polling station, the following conditions can be observed in the response body:

Postcode search: Address picker 

/postcode/{postcode}.json
Example: https://wheredoivote.co.uk/api/beta/postcode/SW1A1AA.json

Parameters

  • postcode string ( required )

    Whitespace in postcodes is ignored, so format may be SW1A1AA or SW1A 1AA

    Example: SW1A1AA

Response 

When we hold data for this area but voters with this postcode don't all vote at the same polling station, the following conditions can be observed in the response body:

  • polling_station_known is false

  • polling_station is null

  • addresses is an array of address objects covered by the input postcode. This can be used to request the user's address and make a second API call to the /address endpoint.

Address search 

/address/{uprn}.json
Example: https://wheredoivote.co.uk/api/beta/address/60017559.json

Parameters

  • uprn string ( required )

    A unique uprn describing a residential address

    Example: 60017559

Response

When we make a valid call to the /address endpoint, the following conditions can be observed in the response body:

  • polling_station_known is true

  • polling_station is a GeoJSON polling station feature

  • addresses is an array of length one containing a single address object describing the requested address

Northern Ireland 

WhereDoIVote will sometimes hold polling station data for Northern Ireland.

If we hold data then the postcode and address endpoints will behave the same for locations in Northern Ireland as those in England, Scotland and Wales.

If we don't have information about polling stations in Northern Ireland we provide an external link to the polling station finder service run by the Electoral Office for Northern Ireland run their own service. e.g:

{
...
  "custom_finder": "http://www.eoni.org.uk/Offices/Postcode-Search-Results?postcode=BT28%202EY"
}

ID Requirements

All voters in Northern Ireland must present photo ID to vote at a polling station.

This information will be provided in all responses from the /address and /postcode API endpoints, even if we are not able to provide a polling station result.
