 Base URL of your Sentry instance. **Only needed for [self-hosted Sentry](./self-hosted/).** SaaS users (sentry.io) should not set this.
 
 ```bash
-export SENTRY_URL=https://sentry.example.com
+export SENTRY_HOST=https://sentry.example.com
 ```
 
 When set, all API requests (including OAuth login) are directed to this URL instead of `https://sentry.io`. The CLI also sets this automatically when you pass a self-hosted Sentry URL as a command argument.
