HTX Will Add a “Serial Number of Account Change” Parameter for Spot API

Dear Valued Users,

HTX plans to add a Serial Number of Account Change parameter for spot API users at 8:00 am on Aug. 19, 2021 (UTC).


The involved interfaces are as below:


  • Interface Name: Query the specific account balance (Added return      parameter seq-num)
  • Interface Type: private
  • Interface URL: GET /v1/account/accounts/{account-id}/balance


  • Interface Name: Subscribe Account Change (Added return parameter seqNum)
  • Interface Type: private
  • Subscription Topic: accounts.update#${mode}


Please note there is a unique serial number for each HTX account change, that is to say, for the same account change, the seq-num recorded in REST interface will be consistent with “seqNum” of WS push. When the WS is unexpectedly disconnected, the data can be retrieved by querying the REST interface.


Thank you for your support!
