E-Receipts IT API

The E-Receipts IT API is organized into two logical suites: endpoints under the /mf1 prefix handle Merchant and Cashier operations, while those under /mf2 are dedicated to Supplier functionalities. Specifically, fiscal operations within the /mf1 suite (such as commercial document issuance and cash closure) require mutual TLS (mTLS) authentication and must be accessed via port 444.
