Calling Rest API from AX 2012

AX 2012 supports system.Net namespace interface. This interface provides simple programming interface for many of the protocols used on the networks today. Herewith i am sharing a simple example to call a rest API asynchronously.  it is very lightweight and has hardly an impact if you are calling asynchronously.

 

static void CallRestAPISample(Args _args)
{
 System.Net.WebHeaderCollection headers ;
 System.Net.WebClient webclient;
 System.Uri uri;
 
 // Create XML msg or string message as parameter to call the Rest API. 
 str msgstring = '<?xml version="1.0"?> ';
 
 msgstring += '<LogRequest>' ;
 
 msgstring += '<ApplicationName>AX Error Tracking</ApplicationName>';
 msgstring += ' <Date>06-22-2017 12:58:22 PM</Date>';
 msgstring += '<ThreadID>0</ThreadID>';
 msgstring += '<LogLevel> <INFO>false</INFO> <DEBUG>false</DEBUG> <ERROR>true</ERROR> <FATAL>false</FATAL> <WARN>false</WARN> </LogLevel>';
 msgstring += '<LogDetails> <ExceptionMessage>Test Exception</ExceptionMessage> <Message>This is test message from AX Logging Call.</Message> </LogDetails> ';
 msgstring += '<Metadata> <Data> <Name>ENV</Name> <Value>DEV</Value> </Data> <Data> <Name>Server</Name> <Value>AX AOS 1</Value> </Data> <Data> <Name>Source</Name> <Value>DAX</Value> </Data> </Metadata>';
 msgstring += '<Email> <From>FromAddr@Fromserver.com</From> <To>toaddrr@toserver.com</To> <Subject>AX Logging Test</Subject> <Message>This is test message</Message> <HasAttachments>false</HasAttachments> <IsBodyHtml>true</IsBodyHtml> <IncludeLogDetails>true</IncludeLogDetails> </Email>';
 msgstring += '</LogRequest>';
 
 
 info(strFmt("%1",time2str(timeNow(),1,1)));
 // initilizing host URI
 uri = new System.Uri("http://LogginServiceHost/api/Log/LogRequest");// FAKE SERVICE HOST ADDRESS
 // initializing webClient
 webclient = new System.Net.WebClient();
 headers = webclient.get_Headers();
 // Set header content type
 Headers.Add(System.Net.HttpRequestHeader::ContentType, "text/xml;charset=utf-8");
 // call API asynchronously
 webclient.UploadStringAsync(uri,msgstring);
 
 info(strFmt("%1",time2str(timeNow(),1,1)));

}
