Facebook API Marketing with UrlFetchApp

_x000D_ This sounds like you actually made a POST request, and not a GET - because posting to this edge is supposed to trigger creation of a report in the background, https://developers.facebook.com/docs/marketing-api/reference/ad-campaign-group/insights/#Creating: When posting to this edge, an AdReportRun will be created. https://developers.google.com/apps-script/reference/url-fetch/url-fetch-app#fetchurl-params, says in the description of the payload parameter, Certain HTTP methods (for example, GET) do not accept a payload. So because you supplied a payload, that probably makes it use POST, and ignore that you tried to specify 'method' : 'get' Don’t supply a payload, append your access token directly to the URL as a query string parameter instead. var url = "https://graph.facebook.com/v4.0/CAMPAIGNID/insights?access_token=…" (You can probably remove the options object completely then, and call fetch with just the URL as single parameter, because GET is the default anyway.)
