What is lead generation? 
Lead generation is the process of online recording of a patient for an appointment with a doctor at a clinic on the site of a Lead Generator and transferring the patient's contacts to the clinic
A lead generator is the owner of a site (application/website) that offers visitors to its resource to make an appointment with a doctor through integration with Medflex.
A lead is a potential client of the clinic (a patient) who has expressed interest in making an appointment with a doctor and has left his contact information indicating the date and time of the appointment, which allows him to be contacted for further interaction.
Online appointment with a doctor is a functionality that allows clients to independently choose a clinic, doctor, appointment time and make an appointment with a selected doctor via the Internet (on the website or in a mobile application) without calling the clinic.
