missing_mode

Minting a key from an account session requires the Facturia-Mode header.

What to do

Send Facturia-Mode: test for an sk_test_ sandbox key or live for a real one. It is not defaulted on this route: a key's mode is immutable (§3.1), so a silent guess hands back a credential that cannot be corrected. An sk_ key inherits its own mode and never sees this.

The envelope

{
  "error": {
    "type": "invalid_request_error",
    "code": "missing_mode",
    "message": "…",
    "hint": "Send `Facturia-Mode: test` for an `sk_test_` sandbox key or `live` for a real one. It is not defaulted on this route: a key's mode is immutable (§3.1), so a silent guess hands back a credential that cannot be corrected. An `sk_` key inherits its own mode and never sees this.",
    "retriable": false,
    "doc_url": "https://docs.facturia.cl/errors/missing_mode",
    "request_id": "req_01K2R7Q9M4T2VB"
  }
}

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.
