Hello,

I wanted to ask here since I wasn't sure whether the API query test only returned a limited number of responses. Does the API provide historical data on polling locations for a given address? And how far does the historical data go, and for which jurisdictions? Is the data overwritten and updated whenever new data becomes available, or can I get both the current and previous polling locations for a given address? 

Also, let me know if I can find more documentation on the API that goes into more detail about data availability. 

Sincerely,
Diego

Hi Diego,

No, the API doesn't include historical data. The data served is our most recent snapshot of polling location information.
You can learn more about the API and the data it serves from our developer documentation.
