+### `servicenow()`
+
+With the `migrate.servicenow()` procedure, you can access [ServiceNow REST API](https://developer.servicenow.com/dev.do#!/reference/api/xanadu/rest/) and transfer your data to Memgraph.
+The underlying implementation is using the [`requests` Python library] to migrate results to Memgraph. The REST API from 
+ServiceNow must provide results in the format `{results: []}` in order for Memgraph to stream it into result rows.
