I have a 3rd party api https://api.twelvedata.com/time_series?symbol=TEST_SYMBOL&interval=1day&apikey=YOUR_API_KEY I have displayed stock price list in the cards. Now I have to show the real time data of each card with each sec changes how do i do that. i have tried many ways but entire api is getting fetched instead of updating data of single card.

CodePudding user response：

Yes, the api provided supports websocket configuration. but if the api is loaded it does not change price i have to refresh the browser and check the price change

CodePudding user response：

Does your API support WebSockets?

What are WebSockets? Websocket is a full-duplex protocol that allows real-time communication between client and web server through emitting and listening for events.
