Error Codes

Error Codes

SymXchange implements a structured error-handling framework that returns an error code and a corresponding response message for each request.

Error codes are generally composed of two elements:

  • Prefix – Indicates the broad category of the detected issue.
  • Status Code – Identifies the specific error or condition that caused the request to fail.

In certain situations, only the status code may be returned.

Together, these values provide both high-level and detailed information about the encountered error, facilitating troubleshooting and resolution.
