Streamline Bulk SMS Sending with JSON: A Guide to Using MySMSGate API

For businesses and developers, efficiently sending large volumes of SMS for customer notifications, promotions, or authentication codes is essential. In this guide, we will explain how to achieve simple and cost-effective bulk SMS sending using JSON format, focusing on the MySMSGate API. Learn how to turn your Android smartphone into a powerful SMS gateway without complex configurations or high costs.

Step 1: Create a MySMSGate Account and Get Your API Key

MySMSGate is an innovative SMS gateway service that utilizes your Android smartphone as an SMS sending and receiving device. It eliminates the need for complex sender registration (e.g., 10DLC in the US) or expensive monthly fees, making it simple and affordable to implement SMS services. Start by creating an account and obtaining your API key.

The biggest advantage of MySMSGate is that it uses your existing Android smartphone and SIM card, allowing you to send SMS at local rates from anywhere in the world. This ensures high delivery rates and cost efficiency, especially in markets with strict carrier regulations like India or Southeast Asia. Furthermore, as it functions as an Android App SMS API, developers can leverage their existing infrastructure while enjoying the robust features of MySMSGate.

Account creation is very easy. Visit the MySMSGate website via the link below, enter the required information, and complete your registration. After registering, an API key will be issued immediately, which you can find in your dashboard. This API key is required for subsequent API requests.

Step 2: Install the Android App and Connect Your Device

Once you have your API key, the next step is to install the MySMSGate app on your Android smartphone and connect it to your account. This app is the key to linking your smartphone with the MySMSGate platform.

• App Installation: Search for the "MySMSGate" app in the Google Play Store and install it on your smartphone.
• Easy Connection via QR Code: After launching the app, simply scan the QR code displayed on the MySMSGate web dashboard to instantly connect your smartphone to your account. There is no need to enter the API key manually.
• Multi-Device and Dual SIM Support: MySMSGate allows you to connect unlimited Android devices to a single account. For example, a business with multiple store locations can connect smartphones from each store, send and receive SMS from their respective phone numbers, and manage everything centrally. Additionally, if you have a dual-SIM smartphone, you can use both SIM slots to send SMS.
• Auto Wake-up Feature: Connected smartphones maintain their connection via push notifications even in sleep mode. This ensures you can send SMS whenever needed.

Once this stage is complete, your Android smartphone is ready to accept JSON SMS sending requests through MySMSGate and deliver messages to the specified recipients.

Step 3: API Basics for Sending Bulk SMS in JSON Format

The MySMSGate API is extremely simple, allowing you to send SMS using just one endpoint: POST /api/v1/send. To meet bulk SMS JSON requirements, the request body is structured in JSON format.

In this section, let's look closer at the basic API request structure and key parameters. Understanding how to use the JSON SMS sending API is the first step toward building an efficient system.

API Endpoint and Request Headers

All API requests are made to the following endpoint:

POST https://mysmsgate.net/api/v1/send

The request headers must include your API key for authentication:

• Content-Type: application/json
• Authorization: Bearer YOUR_API_KEY

JSON Request Body Structure

The JSON body for sending an SMS consists of the following main fields:

• to (Required): The recipient's phone number. Specify in international format (e.g., +8190xxxxxxxx). To send to multiple numbers, provide an array.
• message (Required): The text of the SMS message to be sent.
• device_id (Optional): Specify if you want to send the SMS from a specific Android device. Use the device ID found in the dashboard. If not specified, an available device is selected automatically.
• sim_slot (Optional): For dual-SIM devices, specify 0 (SIM1) or 1 (SIM2) to choose the SIM slot. Default is 0.
• webhook_url (Optional): A URL to receive real-time SMS delivery status updates.

Single SMS Sending Example (JSON)

Below is an example of a basic JSON request body for sending a single SMS:

{
  "to": "+819012345678",
  "message": "Hello, this is a test message from MySMSGate!"
}

Bulk SMS Sending Example (JSON)

To send the same message to multiple recipients, specify an array of phone numbers in the to field.

{
  "to": ["+819011112222", "+818033334444", "+817055556666"],
  "message": "There is an important update. Please check here for details!"
}

This allows you to request the same message for multiple recipients at once in a bulk SMS JSON format. The MySMSGate API queues these messages and sends them efficiently through your connected Android devices.

API Request Example Using Curl

You can use the curl command to easily test the API. Replace YOUR_API_KEY and YOUR_PHONE_NUMBER with actual values.

curl -X POST \
  https://mysmsgate.net/api/v1/send \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{
    "to": "+819012345678",
    "message": "Test from MySMSGate."
  }'

This simple API design allows developers to quickly integrate SMS sending functionality into their applications without complex setups.

Step 4: Python Sample Code for Implementing JSON SMS Sending

The MySMSGate API can be easily used from any programming language. Here, we present Python sample code for JSON SMS sending using the highly popular Python language to explain the specific implementation.

By using Python's requests library, you can easily construct HTTP requests and send JSON data. The following examples show a basic script for sending a single SMS and a script for sending multiple SMS messages.

Python Sample Code: Single SMS Sending

import requests
import json

API_KEY = "YOUR_API_KEY"  # Replace with your API key
TO_NUMBER = "+819012345678" # Replace with the recipient's phone number
MESSAGE = "MySMSGate Python test message!"

url = "https://mysmsgate.net/api/v1/send"
headers = {
    "Content-Type": "application/json",
    "Authorization": f"Bearer {API_KEY}"
}
payload = {
    "to": TO_NUMBER,
    "message": MESSAGE
}

try:
    response = requests.post(url, headers=headers, data=json.dumps(payload))
    response.raise_for_status() # Raise an exception for HTTP errors
    print("SMS sending request successful!")
    print("Response:", response.json())
except requests.exceptions.RequestException as e:
    print(f"An error occurred during the SMS request: {e}")
    if response is not None:
        print("Error response:", response.text)

Python Sample Code: Batch Sending Multiple SMS

This Python code uses the bulk SMS JSON feature to send messages to multiple recipients at once.

import requests
import json

API_KEY = "YOUR_API_KEY"  # Replace with your API key
TO_NUMBERS = ["+819011112222", "+818033334444", "+817055556666"] # Replace with the list of recipient numbers
MESSAGE = "Important notice from MySMSGate!"

url = "https://mysmsgate.net/api/v1/send"
headers = {
    "Content-Type": "application/json",
    "Authorization": f"Bearer {API_KEY}"
}
payload = {
    "to": TO_NUMBERS,
    "message": MESSAGE
}

try:
    response = requests.post(url, headers=headers, data=json.dumps(payload))
    response.raise_for_status() # Raise an exception for HTTP errors
    print("Bulk SMS sending request successful!")
    print("Response:", response.json())
except requests.exceptions.RequestException as e:
    print(f"An error occurred during the bulk SMS request: {e}")
    if response is not None:
        print("Error response:", response.text)

These code snippets demonstrate how simple the MySMSGate API is. With just a few lines of code, you can integrate powerful SMS sending functionality into your application.
