Ccxt: How to get Binance listenKey by sending POST request (browser javascript)?

Created on 1 Apr 2018 · 3Comments · Source: ccxt/ccxt

Hi, as Binance userDataStream requires listenKey (POST data), is it possible to obtain the key using ccxt existing functions with browser javascript? Or is it possible to add and extend ccxt functions to get the listenKey? Thanks a lot for the help.

Reference:
Binance API userDataStream: https://github.com/binance-exchange/binance-official-api-docs/blob/master/user-data-stream.md

OS: MacOS
Programming Language version: browser javascript (using localhost proxy)
CCXT version: any
Exchange: Binance
Method: (looking for a method)

is it possible to obtain the key using ccxt existing functions

Yes, by means of implicit methods – privatePostUserDataStream.

with browser javascript?

Because Binance does not have CORS support yet, you will have to use a CORS proxy: https://github.com/ccxt/ccxt/wiki/Install#cors-access-control-allow-origin

Or is it possible to add and extend ccxt functions to get the listenKey?

We already support all endpoints out of the box, no need to add anything.

Hope it answers your questions. Thx!
