fiscal_profiles

Create a fiscal profile

Register an issuer RFC with its CSD (and optionally FIEL). The simplest way is to upload the raw files via multipart/form-data — curl -F csd_cer=@csd.cer -F csd_key=@csd.key -F csd_password=... -F legal_name=... -F tax_regime=601 -F zip=06000. Sending base64 in a JSON body is the alternative. Private keys are AES-256-GCM encrypted at rest and never returned; the RFC is derived from the certificate. A new profile is created on hold (status: "requires_action") until its carta manifiesto is signed — but if you also send the fiel and a manifest_email, the manifiesto is signed automatically here and the profile comes back active, ready to stamp.

Authorizations

Authorization

string

header

required

API key: Authorization: Bearer sk_test_... or sk_live_....

Headers

Invoice-Version

string

Pin a dated API release (Stripe-style). Omit to use the current version. An unknown value returns 400 request.invalid_version. Echoed back on every response.

Example:

"2026-07-10"

Invoice-Account

string

Connect: act on behalf of one of your connected accounts (its acct_…/org_… id). Omit to act as your own organization. Not honored on /v1/api_keys.

Example:

"org_2P9connectedacct"

Idempotency-Key

string

Safely retry any POST. The first response is stored for 24h and replayed byte-for-byte for identical retries (the replay adds an idempotent-replayed: true header). Reusing the key with a different body is 409 idempotency.key_reuse; an in-flight duplicate is 409 idempotency.key_processing. This makes retrying a 502/429 safe — no duplicate stamp.

Example:

"a1b2c3d4-e5f6-4789-8abc-1234567890ab"

string

required

Issuer legal name (razón social).
