If you trade actively on Deribit, API sync is faster and more complete than CSV export. A read-only API key pulls trades automatically — including funding payments, settlement events, and all instrument types — without manual exports.
Deribit's API key system supports fine-grained permissions. You only need read access to account and trade data — no trading, withdrawal, or account modification permissions.
CSV export is best for one-time historical backfill. For ongoing journaling, API sync removes the friction of repeated manual exports.
