RFC business verification API options for Mexico?
Question
Answer
Answer
Data freshness varies by provider — some cache for 24h, others query SAT on demand. Loan origination generally needs live lookups, which trades some latency for accuracy.
btw does anyone have experience with rfc business verification APIs? trying to build a quick check in our loan origination system — before we lend to a company we want to confirm their RFC is legit and active with SAT.
the flow is simple: we get the RFC from the loan application, hit an API, and either get a green light (RFC valid, business active) or a red flag. we don't need tons of details, just enough to know the business actually exists in SAT's registry.
worried about data freshness — SAT updates their registry periodically but not always in real time. how stale can RFC business verification data be from third-party providers? and is there usually a webhook or refresh option to get the latest data?
