Deploy and Host Secured Signal Rest API on Railway

Secured Signal Rest API is a lightweight authentication proxy for signal-cli-rest-api. It adds bearer token authentication to protect your Signal messaging API, allowing you to safely expose Signal messaging capabilities to your applications without exposing the underlying API directly.

About Hosting Secured Signal Rest API

Hosting Secured Signal Rest API requires deploying two services: the signal-cli-rest-api backend (which handles actual Signal protocol communication) and the secured-signal proxy (which adds authentication). The signal-cli-rest-api service needs persistent storage to maintain your Signal account registration and encryption keys. The proxy sits in front, validating bearer tokens before forwarding requests to the backend. Railway's internal networking allows the backend to remain private while only the authenticated proxy is publicly accessible.

Common Use Cases

Adding Signal notifications to web applications or services
Building chatbots or automated responders on Signal
Integrating Signal messaging into business workflows (alerts, OTP delivery, customer communication)

Dependencies for Secured Signal Rest API Hosting

signal-cli-rest-api (backend Signal messaging service)
Persistent volume for Signal account data and encryption keys

Deployment Dependencies

signal-cli-rest-api - The underlying Signal messaging API
secured-signal-api - Authentication proxy

Implementation Details

Configure the secured-signal service with these environment variables:

API__URL=http://signal-api.railway.internal:8080
API__TOKENS=[your-token-1, your-token-2]

Keep the signal-cli-rest-api service private (no public domain) and only expose the secured-signal proxy publicly. Requests require a bearer token in the Authorization header.
