Way to find Facebook reach from my app posts? - facebook

Question

Is there a way to retrieve the reach from my App posts?
Example:
My app posts photos on a specific fan page, I would like to retrieve the reach that my app provided to that fanpage in order to show them how awesome my app is.

Answer 1

Using the page access token for the page you manage, (with read_insights Permission).
You can then access /POST_ID/insights to retrieve insights information about that post.
For a sample post on my page, this returns the impressions data for the post.
Excerpt:
{
"id": "[ID REMOVED]/insights/post_story_adds_by_action_type/lifetime",
"name": "post_story_adds_by_action_type",
"period": "lifetime",
"values": [
{
"value": {
"like": 20,
"comment": 3,
"share": 1
}
}
],
"title": "Lifetime Post Stories by action type",
"description": "Lifetime The number of stories created about your Page post, by action type. (Total Count)"
},
{
"id": "[ID REMOVED]/insights/post_impressions_unique/lifetime",
"name": "post_impressions_unique",
"period": "lifetime",
"values": [
{
"value": 936
}
],
"title": "Lifetime Post Total Reach",
"description": "Lifetime The number of people who saw your Page post. (Unique Users)"
},
{
"id": "[ID REMOVED]/insights/post_impressions/lifetime",
"name": "post_impressions",
"period": "lifetime",
"values": [
{
"value": 2936
}
],
"title": "Lifetime Post Total Impressions",
"description": "Lifetime The number of impressions of your Page post. (Total Count)"
},
The blog post from when this was launched is here: https://developers.facebook.com/blog/post/573/
And the insights connection is mentioned in the Post documentation
