Call to undefined function etsy_get_object() in etsy_shop.module

I activated "Etsy Shop Details" block and got a fatal error. I assume this function is supposed to fetch information from the webservice.
I'd like to help out here (have a little time during Christmas). Would you like to point me in the direction of your planned solution?
Is it supposed to happen through *_etsy_service_call* or *rest_api_query* somehow?
