Where Do I Vote?

wheredoivote.co.uk Beta API ¶

Open access to the data powering wheredoivote.co.uk: A website to help people in the UK find their polling station, built by Democracy Club.

More information about the project is available on our website

Note this API is currently in beta and outputs are subject to change.

Usage restrictions

Anonymous users are limited to 1,000 requests per day. If you need a higher limit, please contact us to discuss your usage and obtain an API key.

API Root ¶

/.json

Example: https://wheredoivote.co.uk/api/beta/.json

The initial API entry point for discovering endpoints.

Retrieve the Entry Point ¶

Request GET /.json

Response 200

Headers:

Content-Type: application/json

Body:

{
  "councils": "https://wheredoivote.co.uk/api/beta/councils.json",
  "pollingstations": "https://wheredoivote.co.uk/api/beta/pollingstations.json",
}

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

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:

polling_station_known is true
polling_station is a GeoJSON polling station feature
addresses is an empty array

Postcode search: Result found ¶

Northern Ireland ¶

WhereDoIVote will not hold any polling station data for Northern Ireland in 2019.

If we don't know a user's polling station, sometimes we may provide an external link for more info in the custom_finder key. This will always be populated for users in Northern Ireland where 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.
