Transfer funds from SPOT to ISOLATED_MARGIN

trying to transfer fudns from spot to isolate margin using following api request →

There is my query string

I get response - Mandatory parameter ‘amount’ was not sent, was empty/null, or malformed.

What’s wrong with amount??


Try again but format the amount as a decimal, eg. 15.00

I’ve found bug. There is the solving -
“amount” => round($amount,8)
