SAT Catalogs

SAT catalogs define the codes used in CFDI invoices, payments, retentions, and related SAT data. Syntage returns many SAT fields as catalog codes, so these tables help you interpret common values in API responses. This page includes the SAT catalogs most commonly used when reading invoice and retention data through the API. It is not a replacement for the official SAT catalog files, which may include additional codes and validity rules.

​

How to use these catalogs

Use the code from the API response to look up its meaning in the relevant catalog. For example, an invoice with paymentType: "PUE" uses c_MetodoPago, where PUE means payment in one installment. Some SAT catalog values are only valid for specific CFDI versions, dates, taxpayer regimes, or document types. When you need complete validation rules, use the official SAT catalog for that field.
