API pagination best practices

The Solution to API pagination best practices is

I'm not completely sure how your data is handled, so this may or may not work, but have you considered paginating with a timestamp field?

When you query /foos you get 100 results. Your API should then return something like this (assuming JSON, but if it needs XML the same principles can be followed):

    "data" : [
        {  data item 1 with all relevant fields    },
        {  data item 2   },
        {  data item 100 }
    "paging":  {
        "previous":  "http://api.example.com/foo?since=TIMESTAMP1" 
        "next":  "http://api.example.com/foo?since=TIMESTAMP2"


Just a note, only using one timestamp relies on an implicit 'limit' in your results. You may want to add an explicit limit or also use an until property.

The timestamp can be dynamically determined using the last data item in the list. This seems to be more or less how Facebook paginates in its Graph API (scroll down to the bottom to see the pagination links in the format I gave above).

One problem may be if you add a data item, but based on your description it sounds like they would be added to the end (if not, let me know and I'll see if I can improve on this).
