I'm trying to get the number of fans that a music artist has on their Facebook page, but it's not working. I've combed through the FBAPI docs as well as Stack Overflow and still nothing. Here's my code:
func getHolychildInfo() {
//Make request
let newGraphRequest: FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "/holychildmusic/insights/page_fans", parameters: ["period" : "lifetime", "show_description_from_api_doc" : "true", "fields": "read_insights"], httpMethod: "GET")
newGraphRequest.start(completionHandler: { (connection, result, error) in
if ((error) != nil) {
print("Holychild error getting insights: \(error.debugDescription)")
} else {
print("\nHolychild insights result:\n\n\(result)")
}
})
}
Here's my result:
data = (
);
paging = {
next = "https://graph.facebook.com/v2.8/holychildmusic/insights/page_fans?access_token=EAAIB5k3aWEEBAHBD9lZC5AAzZAVV8K8CGBfqaxcrLdZA7oZB2Gdar8cQphXj4VciloZAnZBKp5ZA59BmGloSNz847nFqZCTVsYZCl9rrOk88OnfCnDwwADKnkOO5EUhGumEbW96riHplgfBLdnZAEYmB2Qz4ZAH1sWbuftmGKDqPft4l5QAHSZAimIyI6sOHaKWiurRK201Af6NQCXGliZBsZAUYosUHttkUbo4CQZD&fields=read_insights&format=json&include_headers=false&period=lifetime&sdk=ios&show_description_from_api_doc=true&since=1487457711&until=1487716911";
previous = "https://graph.facebook.com/v2.8/holychildmusic/insights/page_fans?access_token=EAAIB5k3aWEEBAHBD9lZC5AAzZAVV8K8CGBfqaxcrLdZA7oZB2Gdar8cQphXj4VciloZAnZBKp5ZA59BmGloSNz847nFqZCTVsYZCl9rrOk88OnfCnDwwADKnkOO5EUhGumEbW96riHplgfBLdnZAEYmB2Qz4ZAH1sWbuftmGKDqPft4l5QAHSZAimIyI6sOHaKWiurRK201Af6NQCXGliZBsZAUYosUHttkUbo4CQZD&fields=read_insights&format=json&include_headers=false&period=lifetime&sdk=ios&show_description_from_api_doc=true&since=1486939311&until=1487198511";
};
As you can see, there is nothing in the "data" part of the response. The "page_fans" insights metric is supposed to return a number - among other things - but instead returns nothing.
All insights metrics besides the two public ones (page_fans_country and page_storytellers_by_country) require admin access to the page (admin user or page access token with read_insights permission.)
But the fan_count field of the page object is public, so just request that:
