Error Response

Code: 400 Bad Request

{
  "code": "bad_request",
  "message": "Validation failed",
  "errors": [
    {
      "field": "patient_id",
      "message": "must be a string"
    }
  ]
}

Every error has the same shape — a machine-readable code, a message, and an errors[] array that's empty when there's nothing field-specific to report. The HTTP status is authoritative.

Status	code	Meaning
400 Bad Request	bad_request	The request body or parameters failed validation. errors[] names the offending fields.
401 Unauthorized	unauthorized	The access token is missing, malformed or expired.
403 Forbidden	forbidden	The request references a resource outside the token's organisation or clinic scope.
404 Not Found	not_found	No such resource, or it's outside your scope.
429 Too Many Requests	rate_limited	Rate limit exceeded. Back off and retry.
500 Internal Server Error	internal_error	Unexpected server error.
502 Bad Gateway	upstream_error	Upstream service failed or timed out.

Notes

• PATCH is a JSON Merge Patch (RFC 7386): an omitted field is left alone, an explicit null clears it, and an array replaces the existing one wholesale.
