When developing Webpages, they say you should use POST for "destructive" actions, and GET for actions that only retrieve information.
Is the same true for apps? Is it a total no-no to use GET for sending requests from an iPhone app over HTTPS to a Web server for actions such as:
- Creating games
- Updating scores
- Sending messages
(None of the actions are actually "destructive", none of the server functions DELETE anything, though some UPDATE things like high scores, which may be considered destructive since they overwrite stuff.)
I have backups in case of data loss, but I'm asking regardless of this.
