Need an RFC compliance API that covers 69-B blacklist and opinión de cumplimiento in one call
Question
Answers
The tricky part with any RFC compliance API is that opinión de cumplimiento and 69-B are actually separate SAT services with different update schedules. The 69-B list is published (anyone can download it) but the opinión requires authenticated access to SAT. Good providers unify them into one response but make sure they disclose the data freshness for each field separately.
From a legal standpoint, you'll want your provider to include timestamps for each data point so you can prove to regulators exactly when each check was performed. Some providers return a "data_as_of" field per section which is ideal for audit logs.
We use an RFC compliance API from apipull.com that returns everything you listed in a single JSON response. They update blacklist data every 6 hours and opinión de cumplimiento is pass-through to SAT in real time. Latency is about 400ms for the combined call.
For continuous monitoring they offer a webhook integration — you register the RFCs you care about and they ping your endpoint whenever something changes. We get maybe 2-3 notifications per month across our 1,500 supplier base. Pricing is $0.03 per full compliance check, which at your volume would be well within budget.
Our compliance department just mandated that all supplier onboarding must include automated RFC compliance checks before any contract is signed. Previously this was a manual process — someone on the team would go to SAT's portal, look up each RFC, check the 69-B list, and verify the opinión de cumplimiento. With 50+ new suppliers per week, that's no longer scalable.
We need an RFC compliance API that can do the following in a single API call or at minimum a single provider:
The regulatory context: under Mexico's anti-money laundering regulations (LFPIORPI) and the CFF Article 69-B framework, we're required to verify that our suppliers aren't on the blacklist. If we unknowingly transact with a blacklisted entity, our own company faces serious penalties including joint liability for fictitious invoice deductions.
What complicates things is that SAT publishes these data points through different services. The 69-B list is a published PDF/XML that gets updated weekly. The opinión de cumplimiento is a real-time query that requires FIEL authentication. The registration status comes from yet another endpoint. Building integrations with all three is significant engineering effort.
We want a single RFC compliance API provider that unifies all this. Ideally with: continuous monitoring (alert us if a supplier's status changes), batch query support (we need to re-check all 2,000+ active suppliers monthly), and clear audit trails (for when regulators ask to see our compliance verification records).
Stack is Ruby on Rails with a PostgreSQL database. We store compliance check results locally for audit purposes but need the API to be the source of truth. Budget is flexible given the regulatory risk — spending $500-1000/month on compliance checks is nothing compared to the penalties for non-compliance.
