This help page explains how to obtain transaction history.
There are three methods to obtain (prepare) transaction history (four for those with the Advanced Plan or higher):
① Exchange file How to get trade histories from exchanges
② API integration Exchange API Connection
③ Wallet address How to upload a trade history of Metamask wallet?
For customers engaged in DeFi transactions, subscribing to the Advanced Plan or higher allows the upload of wallet transaction history through wallet address integration.
④ Custom trade
Transaction histories outside supported exchanges, peer-to-peer transactions, or transactions not obtainable through files or APIs may require the creation of custom files as needed.
