Technical Integration for International SMS Messaging Between SMS Aggregators

Protocols/Interfaces used when you send SMS messages

Since one SMS aggregator cannot be linked with telecommunication companies in 220 countries, it is necessary to link with an SMS aggregator that provides international message transmission services in each country. 

International messaging between SMS aggregators involves the integration of technical systems for seamless communication between different countries. This integration includes setting up gateways for sending and receiving messages, configuring SMS routing, and establishing connections between the SMS aggregators. 

The technical integration must also ensure that the messaging platform is compliant with the local laws, regulations, and policies in each country. The process involves integrating with different carriers and mobile networks, converting messages into the appropriate format, and ensuring proper encoding, decoding, and routing of messages. The technical integration for international messaging between SMS aggregators must be secure, reliable, and efficient to ensure seamless communication.

In this post, we will be looking in detail about the methods of integration for international message transmission between SMS aggregators.

SMS Gateway Protocols/Interfaces

The SMS gateways of SMS service providers support several protocols or interfaces including HTTP, SMPP, REST API, HTTPS (HTTP + SSL encryption), XML over HTTP / HTTPS, and FTP. Here, we will cover HTTP/s, Rest API, SMPP which are most commonly used. 

  1. HTTP/S

HTTP/S (Hypertext Transfer Protocol/Secure) is a protocol for transmitting data over the internet and is often used in relation to SMS gateways. HTTP/S is used to transfer SMS messages from an application or website to the SMS gateway for delivery to the recipient.

HTTP/S is a secure protocol, with the “S” standing for secure, and provides encryption for the data being transmitted. This makes it an ideal protocol for transmitting sensitive information, such as SMS messages, over the internet. The SMS gateway acts as a bridge between the application or website and the mobile network, using HTTP/S to transfer the SMS message to the mobile network for delivery to the recipient.

In terms of coding, sending SMS messages using HTTP/S is relatively simple, as it is based on standard HTTP methods, such as GET and POST. This means that developers can use existing libraries and frameworks to create applications that use SMS messaging, without having to learn a new protocol.

For example, a simple PHP script could be used to send an SMS message using HTTP/S:

  1. Rest API

REST API (Representational State Transfer Application Programming Interface) is a standard for creating web-based APIs and is often used in relation to SMS gateways. REST APIs provide a way for applications to communicate with each other and with the SMS gateway, making it easy to send SMS messages and receive delivery reports.

With a REST API, applications can use standard HTTP methods, such as GET, POST, PUT, and DELETE, to communicate with the SMS gateway. This makes it easy to integrate the SMS gateway into existing systems and applications, as well as to create new applications that utilize SMS messaging.

In the context of SMS gateways, a REST API can be used to send SMS messages, manage contacts, and retrieve delivery reports. The API provides a simple and straightforward way for applications to communicate with the SMS gateway, making it easy to send and receive SMS messages.

Here is an example of sending an SMS message using a REST API in Python:

This code uses the requests library to make an HTTP POST request to the SMS gateway’s API endpoint with the message text and recipient information in the request body. The response from the API is stored in the response variable, and the status code of the response is checked to determine the success or failure of the message delivery.

Note that this is just a simple example and actual REST API implementations may vary depending on the specific SMS gateway and the requirements of the integration.

  1. SMPP

SMPP (Short Message Peer-to-Peer) is a telecommunications industry protocol for exchanging SMS messages between Short Message Service Centers (SMSCs) and External Short Messaging Entities (ESMEs). SMPP is commonly used by SMS gateways to send and receive SMS messages.

In the context of an SMS gateway, SMPP provides a way for external systems to send SMS messages and retrieve information about messages, such as delivery reports, through a binary protocol over TCP/IP. SMPP is widely used in the telecommunications industry and provides many advanced features, such as delivery receipts, message concatenation, and support for different message encoding schemes.

Coding for SMPP involves creating binary messages that conform to the SMPP protocol specification and parsing binary responses to interact with the SMS gateway. This can be done in any programming language that supports low-level socket programming, such as C, C++, Java, Python, or Ruby.

The coding for SMPP is different from REST APIs, as it uses a binary protocol and requires a deeper understanding of the SMPP protocol specification and its various commands and parameters.

Here is an example of sending an SMS message using SMPP in Python:

Pros and Cons of HTTP/S, REST API, and SMPP

HTTP/S, REST API, and SMPP are different protocols used for SMS messaging.

HTTP/S is a simple, widely supported protocol that is easy to implement and integrates well with web applications. It is commonly used for low-volume messaging and provides basic functionality.

REST API provides more advanced functionality than HTTP/S, such as support for complex message types and delivery receipts. It also offers a more flexible and scalable architecture, making it a good choice for large-scale messaging applications. However, REST APIs can be more complex to implement than HTTP/S and may require more development effort.

SMPP is a powerful, high-performance protocol that is specifically designed for SMS messaging. It provides advanced features such as message concatenation, delivery receipts, and support for different message encoding schemes. SMPP can handle large volumes of SMS traffic, making it a good choice for high-volume messaging applications. However, SMPP can be complex to implement and may require more development effort compared to HTTP/S and REST API.

In conclusion, the choice between HTTP/S, REST API, and SMPP depends on the specific requirements of your SMS messaging application, such as volume, complexity, performance, and scalability.

Important Factors to Consider When Choosing a Protocol/Interface

  • There are several important factors to consider when choosing a protocol or interface for an SMS gateway:
  • Compatibility: Ensure that the protocol or interface is compatible with your SMS gateway provider and the devices or systems that will be using the SMS gateway.
  • Functionality: Consider the functionality required for your use case, such as message concatenation, delivery receipts, and support for different message encoding schemes.
  • Performance: Ensure that the protocol or interface provides adequate performance for your requirements, such as message throughput and latency.
  • Scalability: Consider the scalability of the protocol or interface, particularly if you expect to handle large volumes of SMS traffic.
  • Security: Ensure that the protocol or interface provides adequate security measures, such as encryption and authentication, to protect against unauthorized access.
  • Development Effort: Consider the development effort required to integrate with the protocol or interface, including the ease of use of the API and the availability of libraries and sample code.
  • Cost: Consider the cost of using the protocol or interface, including licensing fees, and the cost of any required hardware or software.
  • It’s important to carefully evaluate each of these factors to ensure that you choose a protocol or interface that meets your specific requirements.
