[ckan-dev] CKAN as an API Proxy

Fri Jan 9 12:09:05 UTC 2015

Hi Andy,

I quite sure this does not yet exist in the context of CKAN, but there are
a lot of similar solutions for API proxies.
Your use case sounds like you need an external API proxy, which handles
requests by the "outside world". The authentication could be done via CKAN,
but I'm not sure why you need it anyway. Is this a private instance of
CKAN? If so, it makes sense, if the data is open, I wouldn't implement the
authentication part.

Apart from the API proxy you want to extend the data model to store two
URLs, one for the proxy and one for the "real" API. This should be doable.
The API proxy can then use the information saved on the CKAN resource to
route the requests. I personally would use something like hapi.js to build
the proxy.
