I am using Feedly API to access feeds from a particular rss feed. Take a look at this link (1). As you see, it only returns newest 20 items but I think it provides sort of a link to paginate to the next result. There is 'continuation' key provided in the result but it is a string and not a link.
How can I use that to fetch the next result? Is this even possible?
See http://developer.feedly.com/v3/streams/
You can pass the continuation key to get the next batch of results.
For example: https://cloud.feedly.com/v3/streams/contents?streamId=feed/http://feeds.engadget.com/weblogsinc/engadget?continuation=14de41de03e:f7bda:87649ed8
