+title: Refreshing Content
+---
+
+During local development, it can be useful to refresh sourced content without restarting the development server. To facilitate this, Gatsby exposes an environment variable called `ENABLE_GATSBY_REFRESH_ENDPOINT`.
+
+If set to `true`, this will expose a `/__refresh` webhook that can receive POST requests to refresh the sourced content. This exposed webhook can be triggered whenever remote data changes.
+
+You can trigger this endpoint locally, for example, on Unix-based operating systems (like Ubuntu and macOS) using `curl -X POST http://localhost:8000/__refresh`.
+
+Additionally, the sourced content can also be refreshed with the "Refresh Data" button in the [GraphiQL explorer](/docs/running-queries-with-graphiql). This button is only visible if `ENABLE_GATSBY_REFRESH_ENDPOINT` is set to `true`.
+
+Securing the refresh endpoint is possible by supplying a value for the environmental variable `GATSBY_REFRESH_TOKEN`, which will cause Gatsby to only accept requests with a matching authorization header. For example `GATSBY_REFRESH_TOKEN=12345` would require a request with header: `authorization: 12345`.
