If your company has an active subscription, you may use the credentials from that account for testing and development with the API. Email us at info@mrmailtracker.com to get an API key. In this case, you'll be testing with live actual tracking data from your account.
        If you do not have an active subscription, a testing account is
        available for developers to use when building applications that use the
        Mr Mail Tracker API.  This test account will allow access to dummy data
        that you can use for testing.

Requests to the API are sent as an HTTP GET request. Data is served back to the client as JSON.
        Each request uses a specific path in the url.  The type of data being
        requested determines which path to use.
        For example, the request for a list of mailings in the system is sent to:
        https://MrMailTracker.com/api/mailings
        The request for details about a particular mailing is sent to:
        https://MrMailTracker.com/api/track_mailing
    
        The specifics of the request are added to the url in a query string.
        Here is an example of a full url to request a list of mailings in the
        system:
        
            https://MrMailTracker.com/api/mailings?login_id=11&user_id=12&search_string=null&key=GsF6CkPmErRh&search_field=null
