This example runs an uploaded CSV file containing contact information through a data cleansing process that uses the Whitepages Pro Find Person API to obtain the most recent information for a given person, given an old address. The use of the is_historical flag on the API request allows you to query the Whitepages databases using out-of-date information.
Create a simple CSV file on your computer with the following eight columns of information: Last Name, First Name, Middle Name or Initial, Street Address 1, Street Address 2, City, State, Postal Code. Then select that file using the HTML file upload component. A cleansed CSV file containing the same number of records, but with updated address and phone information, is sent back and available as a file download.
This example uses the Find Person Whitepages Pro API. It was written in C# using Visual Studio 2013, and runs on the .NET Framework 4.5 and the ASP.NET MVC web framework.
