# Errors

> Common error response patterns for the YouNegotiate API 2.0 reference.

API error responses should use JSON and preserve Laravel validation behavior where applicable.

Common response patterns:

| Status | Meaning                                       |
| ------ | --------------------------------------------- |
| `400`  | Invalid request state                         |
| `401`  | Missing or invalid authentication             |
| `403`  | Authenticated user cannot access the resource |
| `404`  | Resource not found                            |
| `422`  | Validation failed                             |
| `500`  | Unexpected server error                       |

Validation errors include a top-level message and field-level errors.
