+### Custom Environment Variables
+
+You can pass custom environment variables to the Heroku Review App by using the custom-env-vars input in your workflow file. This allows you to set specific environment variables for your review app, which can be useful for testing different configurations.

 - `create` will trigger a Review App creation for the current PR, will fail if the Review App already exists
 - `destroy` will trigger a Review App destroy for the current PR, if any
+- `custom-env-vars` (optional) This input allows you to define environment variables to be passed to the Review App. The format should be a multiline string where each line represents a variable (VAR_NAME=value).
