I know JSON is the returned value structure from REST calls but I want to go the other way... I want to create a list from a JSON blob using REST. Is it possible?
Edit 1: I was pretty vague above so let me elaborate. What I'm asking is could I query a source with REST (doesn't have to be SharePoint; could be anything with a REST endpoint), save its raw JSON, and then turn around and run some JavaScript to create a SharePoint list based on the original list's JSON (complete with site columns and data)?
I expect to have to massage the JSON into a SharePoint-ready format and I know I could hack out an iterator where I send a REST POST to make a list, send more POSTs to make each column, and then yet more iterations for populating data... but I'm just curious if there is even a RESTful way to import JSON as a complete SP list in one swoop.
