This post have over 300000 comments and I want to filter which has my key. I use this api to get all comment, then filter in local, but the maximum comments I receive is 5000.
graph.facebook.com/{post_id}/comments?fields=id&limit=1000000
How can I get all comments without limit (for post page have over million comments)?
Thank
Use a lower limit and use paging instead: https://developers.facebook.com/docs/graph-api/using-graph-api/#paging
You need to be careful with API limits though.
