Connecting to CloudSignal
How to connect your apps and services to the CloudSignal MQTT broker.
CloudSignal uses standard MQTT protocols. Any MQTT client can connect using the broker URL and your organization credentials.
Broker endpoints
| Transport | URL |
|---|---|
| MQTT over TLS | mqtts://mqtt.cloudsignal.app:8883 |
| MQTT over WSS | wss://connect.cloudsignal.app:18885/ |
Authentication
Every connection requires a username and password:
- Username format:
your_username@org_short_id. - Password: the password set when creating the MQTT client.
Your org_short_id is shown in the dashboard under Settings → Organization. It looks like org_k7xm4pqr2n5t.
Connection methods
There are three ways to authenticate MQTT connections:
Auth providers
Use your existing identity provider (Supabase, Firebase, Auth0, Clerk) for zero-password MQTT authentication
Token auth
Generate temporary server-side tokens with 60-minute TTL for client connections
Client credentials
Create static username/password pairs for dedicated services
