Following that standard, the field for a machine-readable "error code" in API v0 is `type`. In our future API v1, we are phasing out RFC 7807 and adopting a custom error format. That format will be documented in our API v1 spec. But you may see some v0 error responses with a machine-readable `code` field while we are making the transition from v0 to v1. properties: code: description: >- An optional “sneak preview” of our future API v1 error responses. This is provided to give integrators a chance to work with our future error codes. Error codes for the same error may change between v0 and v1. example: BAD_REQUEST_BODY type: string detail: description: | A human-readable string explaining this particular error. example: 'missing required fields: first_name, dob' type: string status: description: the HTTP status code for this response example: 400 type: integer title: description: > A human-readable string for this general category of error, which corresponds 1-to-1 with error types (`title` is the human-readable version of `type`). There can be multiple distinct titles for the same HTTP status code, and the same `title` can result in many different `detail` strings. This field will be removed in API v1. example: Bad Request Body type: string type: description: > A machine-readable string that identifies the error for programmatic use. This is a URI, i.e. a globally unique identifier. It is _not_ necessarily a URL, so do not expect it to resolve to a web page. You can use this whole string as an error code, or just everything after the last slash.
