Add option to JSON datasource to deny POST requests

Would like to attach some APIs as data source, which I think is a very helpful feature. But would like to prevent users from doing “POST” requests. It looks like redash already only allows GETs and POSTs.

Hey @tomwganem this is an interesting idea. We’d definitely review/merge a PR implementing this as a setting on the data source setup screen. Would you be interested in implementing?
