Sometimes there is a case where a settlement numbered in your Main Registry does not have the documentation to download. Really in many of these cases it is because the settlement was made in the EACAT Auxiliary Register, which is why we have prepared a FAQ where we want to explain a good practice that you should implement in your applications that interact with our MUX service to resolve these situations.
Details on this FAQ can be found in the MUX integration documentation at the following link: https://consorciaoc.github.io/MUX/FAQ/FAQ.html
