Notes
- Real-Time Data: Once subscribed, you will start receiving real-time data updates based on your subscriptions. The received data will be in JSON format and will contain the relevant information for the subscribed event.
- Close Connection: When you’re done receiving updates or want to close the WebSocket connection, you can gracefully close the connection.
- Security Considerations: Ensure that you keep your Pro-API key secure and do not expose it publicly in your code or any public repositories.
Connection Handling
To provide you with the most reliable and efficient experience, please be aware of the following regarding our WebSocket connections:-
Connection Liveliness (Ping/Pong Mechanism):
- To ensure your connection remains active and healthy, we send a “ping” signal every 10 seconds.
- If we do not receive a “pong” response from your client within 20 seconds of sending a ping, we will automatically disconnect the connection.
- Action Required (Client-Side): Your WebSocket client must be configured to respond to our ping messages with a pong. Most WebSocket libraries handle this automatically, but please verify your implementation to ensure it’s sending pong responses. This is critical for maintaining your connection.
-
Planned Disconnections (Deployments & Reboots):
- Purpose: From time to time, we will perform system reboots or deploy new versions of our service to implement updates, bug fixes, and improvements. These actions require a graceful restart of our servers.
- Impact: During these periods, your active WebSocket connections might be temporarily disconnected.
- Action Required (Client-Side): It is essential that your application is designed to automatically attempt to re-establish the WebSocket connection if it detects a disconnection. Implementing an exponential backoff strategy for reconnection attempts is highly recommended to avoid overwhelming our servers during a widespread disconnection event.
