Hi Justyy, thanks for the reply. Actually the 1.0.19 version of the plugin was updated 2 days ago. I hope it can still qualify for the utopian reward!
Thanks for the tip regarding the real-time transaction records. This is what I originally hoped to do, but could not find an API that I could call via PHP. Essentially I would love an API that I could call from PHP to match a transaction by payee, memo, amount and currency. The best I could find was your transaction history API! Is there an API you have in mind that you can point me to?
Good suggestion about caching data. Yes the data is cached, but not with transients - it is held in memory. I will look into that for a future update.
Thank you very much.
