Server-Sent Events

Server-Sent Events (SSE) is a first-class request type: a streaming GET over the HTTP engine, so it reuses auth, TLS, query parameters, and {{variable}} substitution.

Creating an SSE request

You can start a new SSE request from the sidebar, the tab bar, or the command palette. It operates as a standard GET request configured to handle a continuous stream of data.

Inspecting the event stream

Upon connecting, the in-pane session view will log incoming events in real time. Impostor automatically parses the text/event-stream response, breaking down each message into its constituent parts, such as the event: type, the id:, and the data:. It gracefully handles multiline data and comments.

You can monitor the connection status at a glance and manually disconnect the stream whenever you are finished inspecting the events.
