Me estoy confundiendo acerca de esta cURL de Instagram al convertirla en PHP, vea a continuación:

 curl -F 'client_id=CLIENT_ID' \ -F 'client_secret=CLIENT_SECRET' \ -F 'grant_type=authorization_code' \ -F 'redirect_uri=AUTHORIZATION_REDIRECT_URI' \ -F 'code=CODE' \ https://api.instagram.com/oauth/access_token

aquí está mi código actual con un error

 { "error_type": "OAuthException", "code": 400, "error_message": "You must provide a client_id" }

código actual con valor de muestra:

 $client_id = "7d60c47cdwe249069cdb07a0f28e19cb"; $client_secret = "de5awwe3ebf1443d8dcf0fbc88e5ab1b"; $grant_type = "authorization_code"; $redirect_uri = "http://sexample.net/create-code.php"; $code ="y23d86c19b4c3b0a8b561e64c93f2b3f"; $ch = curl_init(); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); //format URL to grant access to email and sitename passed $data = '{"client_id":"'.$client_id.'","client_secret":"'.$client_secret.'","grant_type":"'.$grant_type.'","redirect_uri":"'.$redirect_uri.'","code":"'.$code.'"}'; curl_setopt($ch, CURLOPT_URL, 'https://api.instagram.com/oauth/access_token'); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json')); curl_setopt($ch, CURLOPT_POSTFIELDS, $data); curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST"); //execute cURL call and get template data $output = curl_exec($ch); curl_close($ch); echo $output;
