Hi, I am trying to authorize my application using API Key from a PHP application . I have the below code. What else am i missing below as its asking for credetails. `$search_host = 'lux.es.eastus2.azure.elastic-cloud.com'; $search_port = '9243'; $index = 'testing12'; $doc_type = '_doc'; $doc_id = 1; $json_doc = array( "user" => "kimchy", "post_date" => "2012-11-15T14:12:12", "message" => "trying out Elastic Search021" ); $json_doc = json_encode($json_doc); $baseUri = 'https://'.$search_host.':'.$search_port.'/'.$index.'/'.$doc_type.'/'.$doc_id; $ci = curl_init(); curl_setopt($ci, CURLOPT_URL, $baseUri); // $headers = array(); // $headers[] = 'Content-Type: application/json, Authorization: WXV3dHUzd0JaUTFVSEYwVDBqZmI6MTVjSjl5bFdUdjZQWm1oZHJMaGhGZw=='; $apiKey = ''; curl_setopt($ci, CURLOPT_HTTPHEADER, array( 'Authorization: ' . $apiKey, 'Content-Type: application/json' )); //curl_setopt($ci, CURLOPT_HTTPHEADER, $headers); curl_setopt($ci, CURLOPT_PORT, $search_port); curl_setopt($ci, CURLOPT_TIMEOUT, 200); curl_setopt($ci, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ci, CURLOPT_FORBID_REUSE, 0); curl_setopt($ci, CURLOPT_CUSTOMREQUEST, 'POST'); curl_setopt($ci, CURLOPT_POSTFIELDS, $json_doc); $response = curl_exec($ci); if ($response === false) { $info = curl_getinfo($ci); curl_close( $ci); die('error occured during curl exec. Additioanl info: ' . var_export($info)); } curl_close( $ci); $decoded1 = json_decode($response,true); if (isset($decoded1->response->status) && $decoded1->response->status == 'ERROR') { die('error occured: ' . $decoded1->response->errormessage); } echo 'response ok!'; var_export($decoded1);` ---

Sorry, your code doesn't have any new lines in it, so it's impossible to read. And you've commented out some parts of the code with `//` so we need the newlines in order to know where the comments end and the code starts again. ---

The API Keys that you generate in the Cloud UI will only provide access to the Elastic Cloud API (`api.elastic-cloud.com`). You cannot use them to access a deployment. For access to individual deployments, you need to [create an API key](https://www.elastic.co/guide/en/elasticsearch/reference/current/security-api-create-api-key.html) within that deployment. ---
