Date filter for facebook conversation/messages using graph API

Question

I am using facebook graph API for reading facebook conversation messages using the following url

https://developers.facebook.com/docs/graph-api/reference/v2.8/conversation/messages/

like- t_mid.1466951718460:2af7cf802579518c97/messages But a conversation may have many messages that are already downloaded. Is there any way to add date filter while reading messages for a conversation? If it is possible, can you please share what should be the querystring for that

Answer 1

like:

/conversation/messages?since=10 March 2015&until=10 March 2016

summary:
since and until must have time format which can converted with strtotime()
