Features

• SMS Messaging: Dispatch SMS messages through a RESTful API.
• Message Status: Retrieve status for sent messages.
• Device Management: View information about connected Android devices.
• Webhooks: Configure webhooks for event-driven notifications.
• Health Monitoring: Access health check endpoints to ensure system integrity.
• Access Control: Operate in either public mode for open access or private mode for restricted access.

Prerequisites

• Go (for development and testing purposes)
• Docker and Docker Compose (for Docker-based setup)
• A configured MySQL/MariaDB database

Quickstart

The easiest way to get started with the server is to use the Docker-based setup in Private Mode. In this mode device registration endpoint is protected, so no one can register a new device without knowing the token.

1. Set up MySQL or MariaDB database.
2. Create config.yml, based on config.example.yml. The most important sections are database, http and gateway. Environment variables can be used to override values in the config file.
   1. In gateway.mode section set private.
   2. In gateway.private_token section set the access token for device registration in private mode. This token must be set on devices with private mode active.
3. Start the server in Docker: docker run -p 3000:3000 -v ./config.yml:/app/config.yml capcom6/sms-gateway:latest.
4. Set up private mode on devices.
5. Use started private server with the same API as the public server at api.sms-gate.app.

See also docker-composee.yml for Docker-based setup.

Work modes

The server has two work modes: public and private. The public mode allows anonymous device registration and used at api.sms-gate.app. Private mode can be used to send sensitive messages and running server in local infrastructure.

In most operations public and private modes are the same. But there are some differences:

• POST /api/mobile/v1/device endpoint is protected by API key in private mode. So it is not possible to register a new device on private server without knowing the token.
• FCM notifications from private server are sent through api.sms-gate.app. Notifications don't contain any sensitive data like phone numbers or message text.

See also private mode discussion.
