Best approach for RFC vendor verification via API?

We cache RFC vendor verification results for 24h with a TTL. On timeout we allow the invoice but flag it for manual review next business day. Keeps AP moving without compliance gaps.
C
Add a circuit breaker — if the RFC API is down, queue verifications and process once it recovers. Don't hard-block payments on infra issues.

I need to build RFC vendor verification into our accounts payable system. Before we pay a vendor invoice, we want to confirm: their RFC is valid and active, the invoice issuer RFC matches the vendor on file, and neither is on the SAT sanctions list.
Right now this is a manual process — our AP team checks SAT's portal. We want to automate it. The tricky part is we need to verify at invoice time, not just at vendor onboarding, because RFC status can change.
Has anyone built a real-time RFC vendor verification integration? What's the typical latency and what do you do if the verification API times out mid-payment-process?
