To search your existing Person record database for records with a particular email address use the 'searchParams' in a GET query.

Example

URL : https://apis.connective.com.au/mercury/v1/:token/contacts?search=true&searchParams=%7B%22email%22%3A%22[email protected]%22%7D

The above GET query when used with your corresponding API Key and Token will search the Contacts database for the email address "[email protected]" and return a list of those records in the response.
