Response codes

OpenNode uses conventional HTTP response codes to indicate the success or failure of an API request. Codes in the 2xxrange indicate success, in the 4xxrange indicate an error that failed given the information provided (usually a required parameter was omitted or incorrectly sent), in the 5xxrange indicate an error with OpenNode's servers.

{ success: false,
  message: 'Error details' }

{ success: false,
  message: 'Error details' }

{ success: false,
  message: 'Error details' }

Our official API libraries raise exceptions when errors are thrown. We recommend writing code that gracefully handles all the possible API exceptions.
