Auto-Invest Unknown Error

API Spot/Margin API
1

Hello everyone, and good evening from Korea!

I’ve been using Binance API for years and haven’t encountered circumstances like today’s.
The main reason might be that I started to using the Auto-Invest API endpoints.

Today, I spent several hours very focused and tried to resolve the issue myself, and now I’m here, just after signing up for this community. It’s great to be a member here.

I faced two types of troubles:

  1. Converting parameters into a querystring format from a nested object.
  • Nodejs doesn’t have built-in functions that can do this, so I created a function with outputs like this: details[0][targetAsset]=BTC&details[0][percentage]=100
  • This attempt seems to have ended ok, I believe.
  1. I believe my request was made correctly after encoutering various errors, but it still doesn’t work.
    Please review my request and the Unknown error response.

Thanks for the feedback, please find the document for how to pass the parameters.

I think for the details, they should be passed as: details[0].targetAsset=
