A callback URL is the endpoint in your application where the platform will send real-time data. For example, once you’ve subscribed to events or markets, the platform will send relevant data to this URL whenever changes occur. You need to configure your server to handle these callbacks and process the incoming data for use in your application.
The callback should be set up as a POST HTTP call, as the platform will send the data as part of the request body.
Example:
POST <https://localhost:8000/api/callback/market-update>
Make sure your server is capable of handling POST requests at this URL to receive and process the data appropriately.
