This document was generated from CDN thread Created by: Jason Shaffer on 25-06-2013 08:47:16 AM Hi Cisco Dev Peeps,We are doing POST to our MCU and can not get any repsonse but a fault code 201.Here is what we send:$command = "<methodCall><methodName>participant.add</methodName></methodCall>";$command .= "<params><param><value><struct><member><name>conferenceName</name><value><string>Test</string></value></member><member><name>participantName</name><value><string>William</string></value></member></struct></value></param></params>";$command .= "</struct></value></param></params></methodCall>";$ch = curl_init();curl_setopt($ch, CURLOPT_URL, "http://192.168.12.14/RPC2");curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);curl_setopt($ch, CURLOPT_POST, true);$data = array("xmldoc" => $command);curl_setopt($ch, CURLOPT_POSTFIELDS, $data);$output = curl_exec($ch);$info = curl_getinfo($ch);curl_close($ch);Here is our error back:SimpleXMLElement Object ( => SimpleXMLElement Object ( => SimpleXMLElement Object ( => SimpleXMLElement Object ( => Array ( [0] => SimpleXMLElement Object ( => faultCode => SimpleXMLElement Object ( => 201 ) ) [1] => SimpleXMLElement Object ( => faultString => SimpleXMLElement Object ( => operation failed ) ) ) ) ) ) )Since the falut code is a generic one it's obviously hard to troubleshoot. Its also the same error if I just open the page in the browser.One thought is authentication, but we've tried this via URL String http://user:passwd@ipAddress/RPC2. User has admin privs.Can anyone tell use what we are doing wrong?Thanks,-jasonSubject: RE: MCU API Replied by: Jason Shaffer on 25-06-2013 10:26:04 AMWell Made just a little more progress, but are now running into Auth Fault code with verified accounts creditials.Here is what we are sending now: 1$request = xmlrpc_encode_request("participant.add", array("conferenceName"=>"Studio01","participantName"=>"william" ));
2$headers = array();
3array_push($headers,"Content-Type:text/xml");
4array_push($headers,"Content-Length: ".strlen($request));
5array_push($headers, '\r\n');

From the log:479 10:16:50.565 API Warning unable to handle XML RPC request participant.add from 192.168.14.5:60979 - invalid user / passwordIs there anything special that has to be done to the API user?Thanks!Subject: RE: MCU API Replied by: Thomas Bonhomme on 25-06-2013 11:11:05 AMHi Jason,Have a look at the doc, page 7 :The controlling application must authenticate itself to the MCU. Also, because the interface is stateless, every call must contain authentication parameters.
http://www.cisco.com/en/US/docs/telepresence/infrastructure/mcu/api_guide/MCU_API_2-9.pdfHappy coding!ThomasSubject: RE: MCU API Replied by: Jason Shaffer on 25-06-2013 01:23:38 PMHi Thomas,Thanks for the prompt response. Duh, so the Auth is XML Params, not HTTP Auth... Not sure how we missed that one. BTW, it's working now. =)Since the Auth is sent in CLEAR TEXT, is the only way to do HTTPS is via encryption key?Thanks,-jason
Subject: RE: MCU API Replied by: Thomas Bonhomme on 25-06-2013 03:29:40 PMGlad this is now working and yeah, you need either the Secure management (HTTPS) or Encryption key to get https enabled. Check with your Cisco Rep. but I believe those keys are free of charge.
