# Error Codes

In general, we recommend that you build your application's error-handling logic around `code` values and `details` payload properties. These properties and their values better reflect the underlying error. As `message` is part of the value, the code name does not have a dedicated property in the API error response payload. However, we recommend that you do not rely on the code name to build error-handling logic, because the code name will eventually be deprecated.
