Error Responses

Standard Error Responses

The API uses standard HTTP status codes to indicate the outcome of an API request.
  • A status code in the 2xx range indicates that the operation was completed successfully.
  • A status code in the 3xx range indicates a redirect. This is only used for specific calls, for example for fetching attachments.
  • Any other status code indicates that the operation has failed:
  • A status code in the 4xx range indicates that invalid input from your side is responsible for the error.
  • A status code in the 5xx range indicates that an internal server error on the JourneyApps side is responsible for the error.
In addition to the HTTP status, a JSON error response is returned, with the following fields:
An unique identifier for the type of error. The type and/or the HTTP status code should be used by the client to determine the type of error.
A short human-readable title for the error. This can change at any time, and should never be used by a client to determine the type of error.
Gives more information on what went wrong. This can change at any time, and should never be used by a client to determine the type of error.
An URL with more information on the error.
