What is a match?
A match is any API response that returns additional data. For example, a match for People Append means CircleBack will return additional information based on a matched email or phone number. A match for Company Append means CircleBack will return additional information based on a matched domain. A match in the Search API means that CircleBack provides net new search results based on search criteria submitted by the user.
