Thought Leadership February 16, 2026 CRiskCo The SAT web service is a powerful tool that allows businesses and developers to automate the querying and downloading of fiscal information directly from Mexico's Tax Administration Service systems. Maximizing this tool can transform the operational efficiency of any business in Mexico. ## What is the SAT web service? The SAT web service is a programming interface (API) that enables automated communication between external systems and the SAT platform. Through this interface, companies can perform queries, validations, and downloads of fiscal information without manually accessing the SAT portal. For a broader overview of all available APIs, see our guide on [SAT APIs for business](/en/blog/sat-apis-negocios). Main available services include: - **Bulk CFDI download:** Automated retrieval of all issued and received tax receipts - **Receipt validation:** Verification of electronic invoice status - **RFC lookup:** Federal Taxpayer Registry validation - **List verification:** Query of SAT lists 69 and 69-B ## Ways to maximize the web service \### 1. Accounting automation Connect your accounting system directly to the web service to automatically download all received CFDIs. This eliminates the need to manually request invoices from suppliers and ensures your accounting reflects all fiscal transactions. \### 2. Real-time fiscal reconciliation Use bulk downloads to compare CFDIs registered in your system with those appearing at the SAT. This helps detect discrepancies, missing invoices, or canceled receipts that could affect your declarations. \### 3. Automated credit analysis Financial institutions can use the web service to obtain a complete picture of a credit applicant's fiscal activity. CFDIs reveal actual sales volume, client concentration, revenue seasonality, and commercial relationships. \### 4. Supplier due diligence Automate supplier verification by checking their RFC status, presence on blacklists, and validity of invoices they issue. This is fundamental for anti-money laundering compliance. \### 5. Continuous portfolio monitoring Set up periodic queries to monitor changes in the fiscal status of clients and counterparties. A status change, appearance on 69-B lists, or decrease in invoicing can be early warning signs of risk. ## Technical requirements To use the SAT web service you need: - **CIEC or e.firma** of the taxpayer (with their consent) - **Digital seal certificate** for authentication - **Technical infrastructure** capable of handling SOAP/REST protocols - **Secure storage** for downloaded data - **Regulatory compliance** with data protection regulations ## Common challenges and solutions - **Service intermittency:** Implement retry mechanisms and processing queues. Check our [SAT availability monitoring](/en/sat-service-status-mexico) for current data. - **Download limits:** Schedule downloads during low-demand hours - **Data volume:** Use asynchronous processing to handle large volumes of CFDIs - **API changes:** Keep your integration updated with the latest versions ## CRiskCo's approach CRiskCo has built a robust platform on top of the SAT web service that doesn't just download data — it transforms it into actionable intelligence. Our analysis engine processes thousands of CFDIs in seconds to generate the FinScore, identify risk patterns, and provide insights that go far beyond the SAT's raw information. * * * ## Access SAT Data Through CRiskCo Did you know you can connect to the SAT web service without building your own infrastructure? **CRiskCo is your gateway to the SAT API.** By registering on our platform, you get automated access to SAT fiscal data — including bulk CFDI downloads, RFC validation, and continuous monitoring — all through a modern, reliable API.
