I am using API version 2.9 I would like to be able to get the the following values.
Currently I am only able to retrieve comments and shares 'On Post' using
FACEBOOK_ROOT_URL/POST_ID?fields=shares,comments
In contrast I am able to get the total and 'On Post' values on reactions with which I can calculate the 'On Shares' value. For example in the context of likes...
The query: FACEBOOK_ROOT_URL/POST_ID?fields=reactions.type(LIKE).summary(total_count),insights.metric(post_reactions_by_type_total)
The post_reactions_by_type_total lists all of the reactions types and their totals while reactions.type(LIKE).summary(total_count) returns the 'On Post' likes. Are there a similar metrics related to comments and shares providing either the total or 'On Shares' value?
