If you add a contact via the API is it passed through any of the de-duplication rules? I.e. if I add a contact that matches an existing record will it create a new record or merge with the existing record?
If the contact is passed through the de-duplication rules how can you control which rule applies?
I am wondering if I need to create the necessary logic in my code to test if a new contact is a duplicate or if I can rely on the de-duplication process to take care of this.
