Python client for SGC (SMS Gateway Center) API. Send SMS, manage account, sender IDs, schedules. Works with Unify SMS Gateway Center.

SGC Python SDK

Python client for the SGC (SMS Gateway Center) API. Send SMS, manage account, sender IDs, schedules, contacts, groups, and more. Works with Unify SMS Gateway Center.

Requirements: Python 3.7+, requests>=2.28.0

---

Prerequisites: Get Your API Credentials

You must have a registered account and API credentials from Unify SMS Gateway Center before using this SDK.

1. Register or log in at https://unify.smsgateway.center.
2. After login, get your API credentials from your account/settings (username, password, and API key).
3. Create or use an existing Sender ID for sending SMS (required for the send API).

Without valid credentials from Unify, all API calls will return authentication errors (e.g. invalid credentials).

Installation

From PyPI

pip install sgc-python-sdk

From GitHub

pip install git+https://github.com/smsgatewaycenter/sgc_python_sdk.git

Local / development

cd /path/to/parent-of-sgc_python_sdk
pip install -r sgc_python_sdk/requirements.txt

To use the package from your code, set PYTHONPATH to the parent directory of sgc_python_sdk:

export PYTHONPATH=/path/to/parent-of-sgc_python_sdk
python -c "from sgc_python_sdk import sgc_auth, sgc_account; print('OK')"

---

Configuration

Set these environment variables with your Unify credentials:

Variable	Required	Description
SGC_API_BASE	No	API base URL. Default: https://unify.smsgateway.center
SGC_USER	Yes	Your Unify username
SGC_PASS	Yes	Your Unify password
SGC_APIKEY	Yes	Your API key from Unify

Optional (for sending SMS and debugging):

Variable	Description
SGC_SMS_PHONE	Recipient number for the test script (e.g. 919876543210)
SGC_SMS_SENDER	Your Sender ID for the test script (e.g. SMSGAT)
SGC_SMS_TEXT	Message text (default: Test from SGC Python SDK)
SGC_SMS_TEST	Set to true for test mode (no real delivery when supported)
SGC_DEBUG	Set to 1 to print full request URL and parameters (sensitive values masked)
SGC_USE_INDEX_PHP	Set to 1 if Send SMS returns 404 (uses index.php?url=... style URL)

---

How to Test

After installing and setting your credentials, run the included test script to verify account, profile, sender IDs, schedule, and (optionally) send SMS.

1. Set your Unify credentials and API base:

   export SGC_API_BASE="https://unify.smsgateway.center"
   export SGC_USER="your_unify_username"
   export SGC_PASS="your_unify_password"
   export SGC_APIKEY="your_api_key_from_unify"
   

2. Run the test script:

   • If you installed via pip (PyPI or GitHub):

     python -m sgc_python_sdk.test_sdk
     

     Or from the repo root:

     python sgc_python_sdk/test_sdk.py
     

   • If using locally with PYTHONPATH:

     export PYTHONPATH=/path/to/parent-of-sgc_python_sdk
     python sgc_python_sdk/test_sdk.py
     

3. What the test does:

   • 1) Account ReadAccountStatus – checks your account status.
   • 2) Account ReadProfile – fetches your profile.
   • 3) SenderId Read – lists your sender IDs.
   • 4) Schedule Read – lists scheduled messages.
   • 5) Send SMS (batch) – only runs if you set SGC_SMS_PHONE and SGC_SMS_SENDER (see below).

4. To test sending an SMS, set the recipient and a valid Sender ID from your account:

   export SGC_SMS_PHONE="919876543210"
   export SGC_SMS_SENDER="YourSenderId"
   python sgc_python_sdk/test_sdk.py
   

   Use SGC_SMS_TEST=true for test mode (no real delivery when the API supports it). Use SGC_DEBUG=1 to see the full request URL and parameters.

If you see invalid credentials (216), double-check your username, password, and API key from Unify SMS Gateway Center.

Quick Start: Use in Your Code

from sgc_python_sdk import sgc_auth, sgc_user, sgc_account, sgc_senderid, sgc_sms, sgc_sms_send

# Use your Unify credentials
auth = sgc_auth()
auth.setUsername("your_unify_username")
auth.setPassword("your_unify_password")
auth.setApiKey("your_api_key_from_unify")

# Account status
user = sgc_user("json")
acc = sgc_account(auth, user)
print(acc.ReadAccountStatus())

# Send SMS (batch)
sms = sgc_sms("json")
sms.setSenderId("YourSenderId")   # Must exist in your Unify account
sms.setText("Hello from SDK")
sms.setPhone("919876543210")
sms.setMsgType("text")
sms.setTestMessage("false")       # "true" for test mode
sms.setDuplicateCheck("true")
sender = sgc_sms_send(auth, sms)
print(sender.batch())

You can also use environment variables and leave credentials out of code:

import os
from sgc_python_sdk import sgc_auth, sgc_user, sgc_account

auth = sgc_auth()
auth.setUsername(os.environ.get("SGC_USER", ""))
auth.setPassword(os.environ.get("SGC_PASS", ""))
auth.setApiKey(os.environ.get("SGC_APIKEY", ""))

user = sgc_user("json")
acc = sgc_account(auth, user)
print(acc.ReadAccountStatus())

API Overview

Area	Class / module	Main actions
Account	sgc_account	ReadAccountStatus, ReadProfile, etc.
Sender ID	sgc_senderid	Read, Create, Update, Delete
Schedule	sgc_schedule	Read, Update, Delete
Send SMS	sgc_sms_send	batch(), phonebook(), file()
API Key	sgc_apikey	Create, Read, Update, Delete
Contact	sgc_contact	CRUD
Group	sgc_group	CRUD
Password	sgc_password	Change
Reseller	sgc_reseller_user_api, sgc_credit_management	User and credit management

Boolean parameters such as testMessage and duplicateCheck must be "true" or "false"; the SDK normalizes them for you.

---

Troubleshooting

• Invalid credentials (216)
  Ensure you are using the correct username, password, and API key from https://unify.smsgateway.center.

• Send SMS returns 404
  Set SGC_USE_INDEX_PHP=1 so the client uses the index.php?url=... style URL.

• Parameter testMessage / duplicateCheck error (147)
  The SDK sends "true" or "false" automatically; ensure you are on a recent SDK version.

• See exact request URL and parameters
  Set SGC_DEBUG=1 and run your script again; the full URL and body params will be printed (sensitive values masked).
