Description: The subscription payload is the information sent to clients when a subscription event occurs. In the context of GraphQL, it refers to the data transmitted to clients in real-time through a persistent connection, such as WebSockets. This feature allows developers to create interactive and dynamic applications where users can receive instant updates without needing to refresh the page or make new requests. The subscription payload is structured in a specific format that includes the event type, relevant data, and often a unique identifier to facilitate connection management. This ability to receive real-time data is especially valuable in applications that require high interactivity, such as online chats, real-time change tracking applications, and collaboration platforms. The subscription payload enhances the user experience by providing up-to-date information immediately and optimizes resource usage by reducing the need for repeated requests to the server.
