Not getting all asset balances in derivatives API

Hi All:

I want to integrate binance futures through API key and when I use fapi/v2/account API, it returns all asset balances zero except USDT balance. Even I did three buy trades on XRPUSDT pair. So It must shows balance for XRP wallet but it shows zero.

See if those BUY orders were indeed successful and use Website or other method to see if the account has indeed non zero balance for XRP (just to be 100% sure).
