API v1 Error Codes

You are here:

The API will return an Error code and in some cases an error message if there was something wrong with your call. All uamplified API error codes are distinguishable by them always starting with a capital U followed by a three digit number. Note that these are errors related to the API and differ from regular Server Response Codes e.g. 404 file not found.


All requests must be made over HTTPS! All other calls are ignored by the service!
