问题
I have looked all over the internet and have not found an answer.
I admin a buy and sell group on facebook and am querying the group/feed through the facebook graph api. If I post in the group as a 'discussion' post it shows up in the query results, but anything I post as a 'buy/sell' post does not come through in the query results. Is there anything in the graph API for querying buy/sell posts in a group?
回答1:
I have same problem now. Before query with field 'feed' gave me all type of post from group, but now only discussion appear in response. Did you use 'posts' field?
回答2:
This is still a problem as of April 2020. Posts to a group which have a sale_post_id in the query string on their detail page come back from the /feed endpoint without any content, only an id and an updated_time parameter.
No documentation referencing Sales Posts appears to exist in the Group Feed graph API documentation.
As far as I can tell, there is no present solution for programmatic access to these post types.
