How this service works
Verifies a Mexican electronic invoice (CFDI) with SAT (JSON body, not query params): status (vigente/cancelado), cancelability, and EFOS validation. Requires a real CFDI's UUID, issuer and receiver RFCs, and total; the example values are illustrative and return 404 (not charged).
Output
Returns the CFDI's SAT status (vigente or cancelado), whether it can be cancelled, and EFOS validation results for both the issuing and receiving RFC — confirming the invoice's authenticity and fiscal standing with Mexican tax authorities.
Example use cases
Supplier invoice approval workflow
“Before I approve this supplier payment, can you check the CFDI with UUID 9a3f1c22-1d45-4b78-83e0-1a2b3c4d5e6f? The issuer RFC is SUP123456AB1, receiver is our company RFC EMP890101AA2, and the total is 58300.50 — I need to confirm it's vigente and not flagged on EFOS.”
Accounts payable audit validation
“I'm auditing a batch of invoices and need to verify this one with the tax authority: CFDI UUID 7b2e9d14-3f56-4c89-a012-b3c4d5e6f7a8, issued by RFC VEN980901BC3 to RFC CLI760203DE4, for a total of 120000.00. Is it active, cancellable, and is the issuer clean on EFOS?”
Fraud detection on received invoice
“A vendor just sent me an invoice and I want to make sure it hasn't been cancelled or faked — UUID is 3c4d5e6f-7a8b-9c0d-e1f2-a3b4c5d6e7f8, RFC emisor is FRA010101GH5, RFC receptor is REC550615IJ6, total is 8750.00. Please check it with SAT and tell me the EFOS status.”

Use this endpoint when you need to programmatically verify the legitimacy and status of a Mexican CFDI invoice against SAT, especially in accounts payable automation, compliance auditing, or fraud detection workflows where confirming vigente status and EFOS clearance is required before processing payments to Mexican suppliers.
Side effects
- 404 returned for non-existent or illustrative UUIDs not found in SAT records
- Invalid RFC format causes validation rejection
- Malformed UUID format returns an error
- SAT service unavailability may cause timeouts
- Mismatched total or RFCs not matching SAT records may return not-found or mismatch errors
