Both work, but each has quirks. SFTP is simple and reliable for batch files, but delays data until the next drop. APIs are closer to real time but depend on rate limits and uptime.
Whichever you use, monitor for missing files and duplicates. This page on SFTP integration explains the batch approach. Which do you prefer?
