Configure your app with environment variables. All values are encrypted at rest.
Setting Variables
Go to Services > PaaS > [Your App] > Env Vars.
Click Add Variable, enter the key and value, and save. Your app will restart automatically.
System Variables
These are set automatically and cannot be modified:
| Variable | Description |
|---|---|
PORT | The port your app must listen on |
DATABASE_URL | PostgreSQL connection string (if database provisioned) |
Best Practices
- Never commit secrets to git — use env vars instead
- Use descriptive key names:
STRIPE_SECRET_KEY, notKEY1 - Values are masked in the dashboard (only last 4 characters shown)
- Admins can see full values in the admin panel
Bulk Import
You can set multiple variables at once via the API:
curl -X POST https://your-domain.com/api/client/paas/{appId}/env \
-H "Content-Type: application/json" \
-d '{"vars": {"KEY1": "value1", "KEY2": "value2"}}'
