A Sri Lankan business SMS platform that unifies campaigns, sender identities, contacts, delivery reporting, and developer integrations.
InstSMS is a business messaging platform operated by Inst Technologies (Pvt) Ltd for organizations sending promotional, transactional, notification, alert, and OTP messages across Sri Lankan mobile networks.
The product brings the operational messaging workflow into one workspace. Teams can organize contacts and groups, prepare campaign messages, send immediately or schedule delivery, manage approved sender identities, maintain account credit, and review message outcomes through delivery reporting.
InstSMS also treats messaging as an integration capability rather than only a dashboard task. Its REST API and developer documentation support server-side applications, enterprise systems, automation, and mobile backends. The public developer experience includes implementation paths for PHP, JavaScript, Node.js, Python, Java, .NET, Go, TypeScript, Android, Swift, and iOS, together with an official Node.js SDK.
Account setup follows a guided business workflow: create the workspace, prepare and request the sender identity, then launch messaging through campaigns or API integration. Billing, API-key management, account controls, documentation, and support are presented as connected parts of the same product rather than separate tools.
The result is a focused platform for businesses that need both accessible campaign operations and a programmable SMS gateway, with clear separation between message creation, submission, scheduled delivery, sender management, and delivery visibility.
