Using Certificates with SOAP Services

To integrate the certificate with your Apex:

1. Receive the WSDL for the web service from the third party, or generate it from the application you want to connect to.
2. Generate Apex classes from the WSDL for the web service. See SOAP Services: Defining a Class from a WSDL Document.
3. The generated Apex classes include a stub for calling the third-party web service represented by the WSDL document. Edit the Apex classes, and assign a value to a clientCertName_x variable on an instance of the stub class. The value must match the Unique Name of the certificate that you generated on the Certificate and Key Management page.

This example illustrates editing the Apex classes and works with the sample WSDL file in Generated WSDL2Apex Code. The example assumes that you generated a certificate with the Unique Name of DocSampleCert.

docSample.DocSamplePort stub = new docSample.DocSamplePort();
stub.clientCertName_x = 'DocSampleCert';
String input = 'This is the input string';
String output = stub.EchoString(input);
