How to download my Apple Card transactions?

See if this helps:

Download or export your Apple Card statements and transactions - Apple Support

Note that only monthly “batch downloads” are available.

very frustrating- no way to download current transactions- have to wait until they are in a statement. Should be able to download them before. Ridiculous

Several budgeting and finance cards support Apple Card and syncing with the card, Monarch, Copilot and YNAB are several and there may be more.
