sai sankar 4 Webservice class real time example
Hi All,
Why do we write webservice classes when there is enterprise and partner wsdl? I would like to know in what scenario we write webservice classes instead of enterprise and partner wsdl. Can anyone explain me with real time example.

salesforce provides enterprise and partner wsdl for integration. But you have to write your own web service class when we need to expose a business logic that can be called by the other system.
For ex: consider you wrote a class for adding two numbers in apex and now this method should be called by an external system. so in that you will make it as a web service.
and another scenario where you need to send the customized response to the caller rather than what is provided by using standard salesforce wsdl and sometimes you need to access multiple objects to do the calculations which is not provided by standard WSDL.
Hope it gives you an idea about why we are wrtiting custom webservices.
Thanks

I have already gone through all those trailhead modules. In these they have explained how to do only. but, my doubt is why we should write Apex webservice calsses when there is enterprise/partner wsdl?

This gives me clear idea when to write webservice classes. So if we need any standard operations like update, delete, insert... sharing standard wsdl is enough?
Please correct me, if i am wrong. Otherwise, please explain me with example, where only sharing standard wsdl is enough for integration?
