Hi. I have been desperately looking for a non-phone app Cryptocurrency portfolio tracker that allows the import of previous trades from major exchanges. I don't see where CSV files from those exchanges can be uploaded, so I created the necessary API keys in hopes they would work. My Bittrex API is still "loading" after 15 hours, but since I'm just trying to test on a free account this may be normal. I have noticed that when I view the transactions that are already uploaded from Binance and Coinbase, the screen seems to be limited to only the most recent 50
An external API is a third-party service which provides balances and/or transaction data, that can be used in other applications. API stands for "Application Programming Interface".
Using external APIs, you can develop your own web services to expose your financial data, without needing to provide CryptFolio with any of your own credentials.
For example, you could specify an external API "https://example.com/my_btc_balance", which returns the number "1.0" - signifying that you want to add 1.0 BTC to your portfolio.
The technical specifications for the range of supported External API formats is now available.
