Adding security on transport layer level

Question

Is there any documentation or reference on how to add username and password to the transport layer when making an apex callout to consume a SOAP based service?

Answer 1

You can add custom headers as described in SOAP Services: Defining a Class from a WSDL Document, as demonstrated below:

docSample.DocSamplePort stub = new docSample.DocSamplePort();
stub.inputHttpHeaders_x = new Map<String, String>();

//Setting a basic authentication header

stub.inputHttpHeaders_x.put('Authorization', 'Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==');

//Setting a cookie header
stub.inputHttpHeaders_x.put('Cookie', 'name=value');

//Setting a custom HTTP header
stub.inputHttpHeaders_x.put('myHeader', 'myValue');

String input = 'This is the input string';
String output = stub.EchoString(input);
