When using json_encode, you should provide an associative array or an object to be encoded to JSON, not a string. In your case you are providing a string and you are mixing the headers and post data in the $headers array. I've added the missing CURLOPT_POSTFIELDS option to include JSON encoded post data in the cURL request, allowing the API to receive the query correctly.
<?php $MY_ACCESS_TOKEN = "your_access_token"; $MY_ADSET_ID = "your_adset_id"; $MY_API_ENDPOINT = "your_api_endpoint"; $postdata = json_encode([ '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}}}}' ]); $endpoint = $MY_API_ENDPOINT; $headers = array( "Content-Type: application/json", "Authorization: Bearer " . $MY_ACCESS_TOKEN ); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $endpoint); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $server_output = curl_exec($ch); curl_close($ch); $json = json_decode($server_output, true); var_dump($json); ?>
