I am trying to read custom object data through WSDL. Could you please suggest me how to get the WSDL link for custom objects.
Are you looking for the attached ones ?
Will give you all the object wsdls available:
Wsld for the CustomObjectInstances:
I normally use us the Object WSDL to just create records and the Query WSDL to read records. When creating new object and using Auto Number, you are going to need a way to find the object you just created as the Write doesn't return any id values. On trick I done in the past is to push a GUID into a text field and used that to find it then overwrite the text field with the correct result later.
