The Pushover Open Client API allows advanced users to write their own native clients for receiving push notifications. Developers will need to either have or purchase a Pushover for Desktop license for their Open Client device within 5 days of activation. While the Pushover Open Client API is in beta, it may go through small changes to server responses or recommended behaviors, but there are unlikely to be any major backwards-incompatible changes.
Fourteen APIs have been added to the ProgrammableWeb directory in categories including Sports, Machine Learning, and News Services. Highlights include the Feedster API for integrating applications with RSS feeds and the Ricoh THETA API for programmatic access to 360 degree camera imagery.
