Response format and conventions

This page describes some common conventions we use in the API.


When a request succeeds, the format used in the response depends on the requested one. We strongly encourage you to use JSON, i.e. ask for http://.../../<something>.json in your requests.

For instance, if you ask for http://your-cartoque-server/servers.json, you'll get a list of your servers in json format.

Other formats are natively supported by the applications but should not be used within the API :

  • html : it's for humans, hey!
  • pdf : same here.
  • csv : only used for /servers and /applications for now, might disappear in the future ; NOT DOCUMENTED
  • xml : same as csv, most likely to be removed in the next release since the world now has json :)

HTTP Response code

We'll use the same HTTP status code as everywhere. Here's a list of the subset we'll use, found in the great Stripe's API :

  • 200 OK - Everything worked as expected.
  • 400 Bad Request - Often missing a required parameter.
  • 401 Unauthorized - No valid API key provided.
  • 402 Request Failed - Parameters were valid but request failed.
  • 404 Not Found - The requested item doesn't exist.
  • 500, 502, 503, 504 Server errors - something went wrong on Cartoque's side.

Namespacing conventions

About namespacing objects, we follow the same conventions as, documented here, if I quote John Nunemaker:

Again, we decided on a rule. In this case, all top level objects should be name-spaced, but objects referenced from a top level object or a collection of several objects did not require name-spacing.
