I've been looking around the Internet trying to investigate how to publish a blog post via either rest APIs or other command line tools. However, I have not found a way to do this. How can I publish a blog post (or node) either through a command line, rest APIs, or another way programmatically?
Drupal 6 has a module to publish to a site via external GUI applications. It supports different XML-RPC based blogging APIs, such as the Blogger API, the new Blogger Data API, the MetaWeblog API, and most of the Movable Type API.
In Drupal 7, the module has been removed from core, and it is now a third-party module.
