📱 SMS Gateway for Android™ Python API Client

A modern Python client for seamless integration with the SMSGate API. Send SMS messages programmatically through your Android devices with this powerful yet simple-to-use library.

📖 About The Project

The Python client for SMSGate provides a clean, type-safe interface to interact with the SMSGate API. It's designed specifically for Python developers who need to integrate SMS functionality into their applications with minimal setup and maximum reliability.

Key value propositions:

• 🐍 Pythonic API - Designed with Python conventions and best practices in mind
• 🛡️ Robust Security - Guidance for secure credential handling and optional end‑to‑end encryption
• 🔄 Flexible Architecture - Supports both synchronous and asynchronous programming patterns
• 💻 Type Safety - Full type hinting for better developer experience and fewer runtime errors
• 🔗 Webhook Integration - Simplified webhook management for event-driven architectures

This client abstracts away the complexities of the underlying HTTP API while providing all the necessary functionality to send and track SMS messages through Android devices.

📦 Installation

Basic Installation

pip install android-sms-gateway

Installation with Specific HTTP Client

# Choose an HTTP client:
pip install android-sms-gateway[requests]    # For synchronous use
pip install android-sms-gateway[aiohttp]     # For asynchronous use
pip install android-sms-gateway[httpx]       # For both synchronous and asynchronous use

Installation with Encryption

# For encrypted messages:
pip install android-sms-gateway[encryption]

# Or install everything:
pip install android-sms-gateway[requests,encryption]

🚀 Quickstart

Initial Setup

1. Configure your credentials:

   export ANDROID_SMS_GATEWAY_LOGIN="your_username"
   export ANDROID_SMS_GATEWAY_PASSWORD="your_password"

2. Basic usage example:

import asyncio
import os

from android_sms_gateway import client, domain

# Configuration
login = os.getenv("ANDROID_SMS_GATEWAY_LOGIN")
password = os.getenv("ANDROID_SMS_GATEWAY_PASSWORD")

# Create message
message = domain.Message(
    "Hello! This is a test message.",
    ["+1234567890"],
    with_delivery_report=True
)

# Synchronous Client
def sync_example():
    with client.APIClient(login, password) as c:
        # Send message
        state = c.send(message)
        print(f"Message sent with ID: {state.id}")
        
        # Check status
        status = c.get_state(state.id)
        print(f"Status: {status.state}")

# Asynchronous Client
async def async_example():
    async with client.AsyncAPIClient(login, password) as c:
        # Send message
        state = await c.send(message)
        print(f"Message sent with ID: {state.id}")
        
        # Check status
        status = await c.get_state(state.id)
        print(f"Status: {status.state}")

if __name__ == "__main__":
    print("=== Synchronous Example ===")
    sync_example()
    
    print("\n=== Asynchronous Example ===")
    asyncio.run(async_example())

Encryption Example

from android_sms_gateway import client, domain, Encryptor

# Encryption setup
encryptor = Encryptor("my-super-secure-secret-passphrase")

# Encrypted message
message = domain.Message(
    "This message will be encrypted!",
    ["+1234567890"],
    is_encrypted=True
)

# Client with encryption
with client.APIClient(login, password, encryptor=encryptor) as c:
    state = c.send(message)
    print(f"Encrypted message sent: {state.id}")

JWT Authentication Example

import os
from android_sms_gateway import client, domain

# Option 1: Using an existing JWT token
jwt_token = os.getenv("ANDROID_SMS_GATEWAY_JWT_TOKEN")

# Create client with JWT token
with client.APIClient(login=None, password=jwt_token) as c:
    message = domain.Message(
        phone_numbers=["+1234567890"],
        text_message=domain.TextMessage(
            text="Hello from JWT authenticated client!",
        ),
    )

# Option 2: Generate a new JWT token with Basic Auth
login = os.getenv("ANDROID_SMS_GATEWAY_LOGIN")
password = os.getenv("ANDROID_SMS_GATEWAY_PASSWORD")

with client.APIClient(login, password) as c:
    # Generate a new JWT token with specific scopes and TTL
    token_request = domain.TokenRequest(
        scopes=["sms:send", "sms:read"],
        ttl=3600  # Token expires in 1 hour
    )
    token_response = c.generate_token(token_request)
    print(f"New JWT token: {token_response.access_token}")
    print(f"Token expires at: {token_response.expires_at}")
    
    # Use the new token for subsequent requests
    with client.APIClient(login=None, password=token_response.access_token) as jwt_client:
        message = domain.Message(
            phone_numbers=["+1234567890"],
            text_message=domain.TextMessage(
                text="Hello from newly generated JWT token!",
            ),
        )
        state = jwt_client.send(message)
        print(f"Message sent with new JWT token: {state.id}")
        
        # Revoke the token when no longer needed
        jwt_client.revoke_token(token_response.id)
        print(f"Token {token_response.id} has been revoked")

🤖 Client Guide

Client Configuration

Both clients (APIClient and AsyncAPIClient) support these parameters:

Parameter	Type	Description	Default
login	str	API username	Required (for Basic Auth)
password	str	API password or JWT token	Required
base_url	str	API base URL	"https://api.sms-gate.app/3rdparty/v1"

Authentication Options:

1. Basic Authentication (traditional):

   client.APIClient(login="username", password="password")

2. JWT Token Authentication:

   # Using an existing JWT token
   client.APIClient(login=None, password="your_jwt_token")
   
   # Or generate a token using Basic Auth first
   with client.APIClient(login="username", password="password") as c:
       token_request = domain.TokenRequest(scopes=["sms:send"], ttl=3600)
       token_response = c.generate_token(token_request)
       
       # Use the new token
       with client.APIClient(login=None, password=token_response.access_token) as jwt_client:
           # Make API calls with JWT authentication
           pass

🌐 HTTP Clients

The library automatically detects installed HTTP clients with this priority:

Client	Sync	Async
aiohttp	❌	1️⃣
requests	1️⃣	❌
httpx	2️⃣	2️⃣

Using Specific Clients

from android_sms_gateway import client, http

# Force httpx usage
client.APIClient(..., http=http.HttpxHttpClient())

# Force requests usage
client.APIClient(..., http=http.RequestsHttpClient())

# Force aiohttp (async only)
async with client.AsyncAPIClient(..., http_client=http.AiohttpHttpClient()) as c:
    # ...

Custom HTTP Client

Implement your own HTTP client following the http.HttpClient (sync) or ahttp.AsyncHttpClient (async) protocols.

🔒 Security

Best Practices

⚠️ IMPORTANT: Always follow these security practices:

• 🔐 Credentials: Store credentials in environment variables
• 🚫 Code: Never expose credentials in client-side code
• 🔒 HTTPS: Use HTTPS for all production communications
• 🔑 Encryption: Use end-to-end encryption for sensitive messages
• 🔄 Rotation: Regularly rotate your credentials

JWT Security Best Practices

When using JWT authentication, follow these additional security practices:

• ⏱️ Short TTL: Use short time-to-live (TTL) for tokens (recommended: 1 hour or less)
• 🔒 Secure Storage: Store JWT tokens securely, preferably in memory or secure storage
• 🎯 Minimal Scopes: Request only the minimum necessary scopes for each token
• 🔄 Token Rotation: Implement token refresh mechanisms before expiration
• 🛑 Revocation: Immediately revoke compromised tokens using revoke_token()

Secure Configuration Example

import os
from dotenv import load_dotenv

# Load environment variables
load_dotenv()

# Secure configuration
login = os.getenv("ANDROID_SMS_GATEWAY_LOGIN")
password = os.getenv("ANDROID_SMS_GATEWAY_PASSWORD")

if not login or not password:
    raise ValueError("Credentials not configured!")
