Apex class methods can be exposed as custom SOAP Web service calls.
This allows an external application to invoke an Apex Web service to perform an
action in Salesforce. Use the webservice
keyword to define these methods. For
example:
global class MyWebService {
webservice static Id makeContact(String contactLastName, Account a) {
Contact c = new Contact(lastName = contactLastName, AccountId = a.Id);
insert c;
return c.id;
}
}
A developer of an external application can integrate with an Apex class containing
webservice methods by generating a WSDL for the
class. To generate a WSDL from an Apex class detail page:
- In the application from Setup, enter “Apex Classes” in the Quick
Find box, then select Apex Classes.
- Click the name of a class that contains webservice methods.
- Click Generate WSDL.
