## What to do [#what-to-do]

FACTURIA FILES IT (ruling 1 of the 2026-09-04 audit), with the certificate it holds in custody — which authenticates its HOLDER, the representante legal, and is the same mechanism that ran a whole boleta certification from code. What is owed is the titular's DECISION about when: postulating costs an empresa on the Sistema de Facturación Gratuito its «calidad de usuario activo» the moment the SII authorizes it, so the moment is theirs to choose. `onboarding.steps[]` carries the approval page for it; once approved we run it and the step moves without anybody logging in anywhere.

## The envelope [#the-envelope]

```json
{
  "error": {
    "type": "unprocessable_error",
    "code": "postulacion_required",
    "message": "…",
    "hint": "FACTURIA FILES IT (ruling 1 of the 2026-09-04 audit), with the certificate it holds in custody — which authenticates its HOLDER, the representante legal, and is the same mechanism that ran a whole boleta certification from code.

Program against `code`, never against `message` — the prose can be rewritten, the code cannot (§5.8).

`hint` and `retriable` arrive in the response with these exact values: they are a function of `code` and come from the same dictionary `GET /v1/error_codes` serves, so the envelope and the dictionary cannot disagree. Both are English on the wire by design — one registry, one language. More in [The error envelope](/en/docs/errores).
