Data extraction from online event-based social network (Meetup Website)

I need to extract data from the Meetup website for three major cities (Delhi, Mumbai, Bangalore) for the year 2018. There are three types of elements in the Meetup: Groups, Events, and Users. Details of the data that I want to extract: 1) For each active and public Group in three major cities in the given year: id, name, description, tags, #members, category id & meta-category id, organizer id & name. 2) For each Event organized in three major cities in the given year: id, name, description, tags, organized by which group, organizer id & name, category id & meta-category id, venue/location, date, time, # participants, events with similar tags organized a week before and two weeks after the current event's date. 3) For each user of the three major cities in the given year: id, name, registered geographical location, tags, member of groups, events attended, events organized (if any), friends or members follow him.
