+### Proxy support
+
+This action relies on Node.js native proxy support.
+
+If you set `HTTP_PROXY` or `HTTPS_PROXY`, also set `NODE_USE_ENV_PROXY: "1"` on the action step so Node.js honors those variables. If you need proxy bypass rules, set `NO_PROXY` alongside them.
+
+```yaml
+- uses: actions/create-github-app-token@v3

+  env:
+    HTTPS_PROXY: http://proxy.example.com:8080
