Error codes

We use standard HTTP error codes to indicate success or failure of a request. Any request that returns HTTP 200 indicates success. Any HTTP 50x indicates that something failed server-side. If you see persistent HTTP 50x errors please contact us.

HTTP 40x errors indicate that something is wrong with your request. For instance:

Code	Meaning
400	Your request is missing a required parameter
401	Your API key is invalid
403	Your API key does not permit access to the resource
404	The resource (session, KM etc.) could not be found
