Library to interface with per-state online voter registration APIs
State Registration APIs
This repo contains:
VoteAmerica's documentation on how to work with states' online voter registration system.
ovrlib, a python library to interact with state APIs
Most states in the US provide online voter registration (OVR) systems (you can find links to all of these systems in our Election Information API).
If you are building a website or a system to direct voters to these registration systems, a few states have gone beyond just letting you link to their OVR website, and provide some additional capabilities:
Tracking Links: Your organization can be issued a unique partner code. Then, you pass this partner code in the URL parameters when directing voters to the state OVR website. The state will then give you some information about the voters who register using your link -- sometimes just aggregate statistics, and sometimes individual voter file entries.
Prefilling Links: If you already have some information about the voter, some states will allow you to pre-fill some information about the voter so they don't have to re-enter it on the state website. For some states, you'll just pass this information in the URL parameters when sending them to the state OVR site. For some states, you'll call the state's API with the pre-filled information, get back a token from the state, and then pass that token in the URL.
Full Registration API: A small number of states offer full-features APIs to submit voter registrations directly to the state. This means that voters never need to leave your website -- they can enter in all their information directly on your site, and you can submit the information to the state on their behalf. Many of these APIs also support batch submissions -- so if you collect voter information offline, you can submit that noninteractively. These APIs tend to be complex, and the state usually has to review and approve your website or application before you can use them.
While these tools are very useful, it's difficult to find good information on them. Often, they're not mentioned on the state websites at all and you have to know the right person to call or email about them. In addition, the APIs often have tricky requirements or other challenging aspects to implement.
This repository is an attempt to make this process easier to navigate. It includes:
- A listing of which states have systems you can integrate with
- Details instructions on how to get access to these systems -- who to call or email, what approvals you'll need, and how long it typically takes.
- ovrlib, a clean, readable Python library for interacting with the Full Registration APIs and the prefilling token APIs that you can use as-is, or read the source code of to understand how the systems work. For many of these systems, there are not official reference implementations so we are trying to provide good reference implementations here.
A Word of Warning
While we do our best to keep this information up-to-date, this is not an authoritative source. Any information you get from the states supersedes anything in this repository. You are responsible for reading, understanding, and complying with any agreements you make with the states while setting up these integrations.
We provide the software in this repository as-is, without warranty of any kind, as laid out in the LICENSE file. While we hope that the code in the repository is useful, you are ultimately responsible for any systems you build using this code, and for complying with all local, state, and federal regulations around election and voter registration systems.
This table lists all the states with any sort of API or integration. You can find a separate markdown file in this repository for each state with more information.
