Hi @matthewmcneely , thanks for your quick reply. Sorry I was not clear.
Well, I aim to do a REST API call and that the reponse data will be stored persistently in my database. This to make relationships between nodes I created myself in the database and nodes that are response data from my REST API calls. So basically the same what is shown in the youtube video except for that fact that the responded data does get added to the database. Thanks again.
