Sharing Expertise: Tech Insights and Case Studies

Secured 3G/4G SMS Gateway with HTTP API

Constructed by our expert team in Singapore, this industrial-grade SMS Gateway boasts a minimum of 8 channels, expandable to 32 channels, ensuring high speed and exceptional availability.

Our software gateway solution seamlessly integrates with the hardware gateway device, allowing for independent deployment from physical devices. For instance, a customer can install the gateway device in Singapore while users from any location with an internet connection can access the gateway.

We utilize an HTTP API (JSON web service) as opposed to the conventional COM Port API, enabling any legacy system to easily send SMS messages to recipients.


Secure API and Encrypted Communications

SMS_Encrypted

All system and API access are encrypted via HTTPS, ensuring that communications between user PCs and servers remain secure.

For enhanced PDPA compliance, optional table-level encryption is available for mobile numbers and contact names.

Our API is safeguarded by a 30-character random text string, and multiple API keys can be generated for distinct applications. Each API key can be assigned start and expiry dates for added security.

Strong passwords are provided to users for logging into web interfaces, ensuring a higher level of protection.

Our API supports a priority-based SMS queue with six levels, capable of handling a large volume of incoming sending requests and organizing SMS messages based on priority.
