Read this thread in its entirety (well, except the parts where my eyes glazed over) yesterday.  I didn't see my question addressed so I'll ask...

Have you approached Hashnest/Bitmain about getting transaction information?

The transaction log entry types include at least:

• deposit
• withdrawal
• hash shop purchase
• hash buy
• hash sell
• hash mining payout for block
• hash maintenance fee for block
• LuckyHash ticket(s) purchase
• LuckyHash win
• PACMIC purchase
• PACMIC payout
• PACMIC reinvest

The transaction log columns are:

• Date (UTC timestamp)
• Amount (+/- up to 8 decimal places, trailing zeros omitted)
• Balance (+/- up to 8 decimal places, trailing zeros omitted), then spacing, then one of { BTC, LTC, ANTL3, ANTS9, ... }
• Type (Contract, Deposit, Trade, Withdrawal, etc.)
• Comment - multiple formats (less than 30 though)

My transaction log as of now has over 1.3 million entries.

I'm hoping that either (a) Hashnest/Bitmain will work with you to directly integrate or (b) at least provide data exporting that you can use.

For the latter, their HTML transaction log is very quick for the most recent 20 transactions but reaching backwards through older pages (including jumping to the last page) is incredibly slow and often times out.

They also have a "Download Report" button that almost always fails/times out -- but when it does work it gives you an Excel (xlsx file).

AFAIK, they've never upgraded their API to allow transaction data downloading directly.  I've also tried using the filtering on the Transactions page to download, for example Jan 1 2017 to Jan 1 2017, and even that small slice of data times out consistently.

Thanks for your time and efforts.
