API5.1 Errors

Ampache's API errors are loosely based around the HTTP status codes. All errors are returned in the form of an XML/JSON Document however the string error message provided is translated into the language of the Ampache server in question. All services should only use the code value.

For Ampache5 error codes are changing and expanding on the information available to the user/client/application that caused the error.

An Ampache5 error has the following parts:

• errorCode: numeric code
• errorAction: method that caused the error
• errorType: further information such as the type of data missing or access level required
• errorMessage: translated error message

Rules Regarding errors

• XML and JSON errors are always in an 'error' object.
• Errors will always provide a code
• The data names user in the error must use names that don't conflict with other data objects
• Allow the ability to drill down even further using the action and type of error
  • errorAction will return the method used that caused the error
  • Use errorType 'system' for things users can't change / server config
  • Use errorType 'account' for user issues (password, perms, auth, etc)
• errorMessage must be a translated string to allow devs to show things for the user in their language.

Error Codes

All error codes are accompanied by a string value for the error and derived from the HTTP/1.1 Status Codes

To separate Ampache from the http codes it's been decided to prefix our codes with 47 to allow clear differentiation

• 4700 Access Control not Enabled
  • The API is disabled. Enable 'access_control' in your config
• 4701 Received Invalid Handshake
  • This is a temporary error, this means no valid session was passed or the handshake failed
• 4703 Access Denied
  • The requested method is not available
  • You can check the error message for details about which feature is disabled
• 4704 Not Found
  • The API could not find the requested object
• 4705 Missing
  • This is a fatal error, the service requested a method that the API does not implement
• 4706 Depreciated
  • This is a fatal error, the method requested is no longer available
• 4710 Bad Request
  • Used when you have specified a valid method but something about the input is incorrect, invalid or missing
  • You can check the error message for details, but do not re-attempt the exact same request
• 4742 Failed Access Check
  • Access denied to the requested object or function for this user
