Direct API

Powerful, flexible messaging. Delivered through a single API.

Boomerang’s direct API provides access to a robust, feature-rich messaging platform, enabling both one-way and two-way communication across SMS, Email, Voice and WhatsApp. It supports advanced capabilities including RCS, AI-driven workflows, and global delivery—giving you the flexibility to build communication into any process, at scale.

Built for developers, the API is designed to be practical, consistent and easy to work with. It supports multiple languages, includes developer shortcuts, and is backed by strong security, high-speed data transfer, and enterprise-grade reliability.

You’ll also benefit from detailed delivery intelligence, including sent, delivered and failed notifications—enabling effective data management, cleansing and optimisation of your communication workflows.

To get started, you’ll receive access to a dedicated sandbox environment, along with complimentary message credits for testing and development. We can also provision multiple accounts under a single developer profile, making it easy to manage environments, clients or use cases.

Beyond the core API, you’ll have access to proven patterns, operational expertise, and ongoing support to help you move quickly from concept to production.
