Using the APIΒΆ

The RESTFul application programming interface is the best way to interact with Clowder programmatically. Much of the web frontend and the extractors use this same API to interact with the system.

Following is a brief description of all the available endpoints. For more information take a look at the source under app/api. All routes are defined in conf/routes. For methods that write to the system a key is required. The default key is available in conf/application.conf under commKey. Please change this to a very long string of characters when deploying the system. The key is passed as a query parameter to the url. For example ?key=sdjof902j39f09joahsduh0932jnujv09erjfosind.

You can use curl to test the service. If you are on Linux or MacOSX you should have it already. Try typing curl on the command prompt. If you are on windows, you can download a build at http://curl.haxx.se/. If you want a more rich GUI experience most web browsers have extensions that can be used instead. For example for Chrome you can try cREST client.
