Endpoint "/sapi/v3/asset/getUserAsset" stop returning balances after a while

API Spot/Margin API
1

Q: What are you trying to do?
A: Fetch balances of an account

Q: What have you done so far?
A: Query get user asset endpoint using binance-connector-ruby gem, following the guidance here: binance-connector-ruby/get_user_asset.rb at master · binance/binance-connector-ruby · GitHub

Q: What endpoints are you trying to hit?
A: /sapi/v3/asset/getUserAsset

Q: What responses are you receiving?
A: At first, the endpoint returns the balances as expected, but after a while, it returns an empty array. I checked and see the balance on the network is still there, so it seems that the problem is from the endpoint.
Here is the balance on the network: TRONSCAN | TRON BlockChain Explorer | 波场区块链浏览器

Additional info: The account I’m trying to fetch the balances for is a sub-account, created by a broker account from the Binance Exchange Link program.

Thanks for the feedback.

  1. what’s the parameters sent to the endpoint “sapi/v3/asset/getUserAsset” when it returns empty array?
  2. When returning empty array, please try to call “/api/v3/account” and see if you have balance. The method for this endpoint is available in the library.
  3. Is it easy to reproduce the issue?

thanks

Hi,

  1. There is no parameter, although I understand that timestamp is required, it seems the library automatically adds that parameter, so it works without specifying it from my end.
  2. I did, it also returns the balance as 0 (which is not correct).
  3. To reproduce this, you can do the following:
  • generate a sub-account from the broker account
  • generate the API key/ API secret for that sub-account
  • generate a deposit address
  • deposit some money into the address
  • query the balance
