Get more than 200 group members from the Meetup API

Using the Meetup API, I'm able to successfully get exactly 200 members from any given group. There are a lot of groups that have more members than that. I want to know how to get them all.

The issue
I haven't been able to find where &page=### is documented. I'm assuming it sets how many results are returned in the response from Meetup.

I have tried using, for example, &page=1000, but I still only get 200 members back.

The request URL
I'm using this URL to request the data:

let meetupReqUrl = "https://api.meetup.com/2/members?&sign=true&group_id=" 
                  + groupId 
                  + "&key=" 
                  + apiKeys.meetup
                  + "&order=joined"
                  + "&page=1000"

This variation also returns exactly 200 members:

let meetupReqUrl = "https://api.meetup.com/2/members?&sign=true&group_id=" 
                  + groupId 
                  + "&order=joined"
                  + "&page=1000" 
                  + "&key=" 
                  + apiKeys.meetup

It may be worth noting that &order=joined is not sorting the results at all. This leads me to believe I am doing something wrong in forming the URL.

Solution

  • It seems the maximum number of results you can get at once through the API is 200 - see https://github.com/jkutianski/meetup-api/wiki#limits.

    You can however make multiple requests as per http://www.meetup.com/meetup_api/#making_request. It says you need to use the page and offset parameters. From the meetup.com link:

    page -- the page size (maximum number of results in each response) to use on the results

    offset -- the starting page for results to return. For example, when page = 10, specifying "offset=0" will bring back records 1-10, "offset=1" will bring records 11-20, etc.
