Add full API #5
Description
Currently this Java library supports only the Notifications API (i.e. sending push messages). This covers 90% of use cases.
Moreover, if you need advanced integrations not covered by this library, you can also use the REST API directly.
However the new Pushpad libraries released for other languages (including Ruby, PHP, Node.js, Python, Go) offer more features, advanced integrations and cover the entire Pushpad API.
It would be nice to add support for the full API also to this Java library.
