create_invoiceIssue a Mexico CFDI 4.0 electronic invoice (factura electrónica, stamped/timbrada through a SAT-certified PAC) via Facturapi. Bring your own Facturapi secret key via header x-facturapi-key — sk_test_ keys are free (sign up at facturapi.io) and never reach SAT; sk_live_ keys stamp real CFDIs. The merchant's CSD certificate lives in their own Facturapi account; this server never sees or stores it. Sensible defaults are applied for SAT catalog fields: product_key 01010101 (generic), payment_form 03 (bank transfer), use G03 (general expenses) — override per item/invoice if the buyer needs specific codes. For a buyer without RFC use tax_id XAXX010101000 with tax_system 616 and use S01.
query_invoiceCheck a Mexico CFDI invoice created by create_invoice. Status values: VALID (stamped and fiscally valid — uuid is the SAT folio fiscal), CANCELED (voided at SAT); cancellation_status pending means SAT is still processing a cancellation. Safe to call anytime.
cancel_invoiceCancel (void) a stamped Mexico CFDI at SAT. SAT requires a cancellation motive code: 01 replaced-with-corrected, 02 issued-in-error-no-replacement (default), 03 transaction-did-not-happen, 04 related-to-global-invoice. Some cancellations need the buyer's acceptance — status stays pending until SAT resolves it.
send_invoiceEmail the stamped CFDI (PDF + XML) to the buyer via Facturapi. Uses the email stored on the invoice unless a different one is passed.
