The task that you want to achieve theoretically can be achieved using a business process that is triggered upon adding record to the contacts section and you need to specify "open edit page" element that will open created record. Also on contact's page you need to add a checkbox which should be checked and it should be defined in conditions which fit created record. For example create a checkbox that is called "Created bia webservice" and when creating a record via webservice you need to transfer the parameter "true" for this checkbox so the record is created with checked checkbox and triggers business process execution that will open edit page of this record.
