Create an invoice

Build and stamp a CFDI 4.0 from friendly JSON. The issuer comes from `fiscal_profile_id` (the only body field the schema hard-requires); every other field is validated in the service, which returns a precise error with remediation if something is missing or wrong. Required for type I (ingreso) and E (egreso): `customer` and at least one `items` line, each with `product_key`, `unit_key`, `quantity`, and `unit_price`, plus `payment_form` and `payment_method` (PUE|PPD; PPD forces payment_form "99"), and a `use` (invoice-level or `customer.use`). Type E (nota de crédito) also requires `relation` ({ type "01" or "03", uuids }). Type P (pago): omit `items`/`payment_form`/`payment_method` and supply `payments` (complemento de pagos 2.0). Set `draft: true` to hold a signed draft and stamp it later. Send an Idempotency-Key to make retries safe.

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"
