I'd like to be able to create a node out of a webform submission in Drupal 8. It can happen either on successful submission or as an additional task after the webform has been submitted. I've seen some info on creating content entities via REST/GET (https://www.drupal.org/docs/8/core/modules/rest/3-post-for-creating-content-entities) and I know that you can post a webform submission to a URL with Webform (yamlform) using either x-www-form-urlencoded or JSON, but I'm not sure if this is even the right thing to be looking at.
The webform, submissions, and content type I'd like to use are all on the same site.
I know this question came up for Drupal 7 and the direction was to have them use a content type, but we're not able to allow the submitters to use content types at this time because of the way the site is setup.
