<p>I have a function that calls the API using JavaScript and it works fine: </p> <p><br /></p> <pre class="brush:js;toolbar:false;">var headers = { Authorization: "Bearer" MY_ACCESS_TOKEN }; var requestParams = { method: "POST", contentType: "application/json", headers: headers, payload: JSON.stringify({ query: 'query {adSet(id: "' MY_ADSET_ID '") {insights(timeRange: {from: "2023-08-01T00:00:00Z", until: "2023-08-10T23:59:59Z"}timeIncrement : DAILY) {timestamps reports {impressions conversions offerwallImpressions offerwallAverageRank spend}}}}' }) var response = UrlFetchApp.fetch(MY_API_ENDPOINT, requestParams); var data = JSON.parse(response);</pre> <p><br /></p> <p>When I try to convert this to PHP, I just get a blank response from the API. What did i do wrong? </p><p> Please note that when I use my_curl() to retrieve $MY_ACCESS_TOKEN from the API, it works fine. </p> <pre class="brush:php;toolbar:false;">$postdata = json_encode('query: query {adSet(id: "' . $MY_ADSET_ID .
